in 2009, JP Industries of Cleveland revived it as Crucible Specialty Metals Division to continue producing specialty steels at its original site. Some of Crucible's products were manufactured using a powder metallurgy process (their CPM process), resulting in steels with superior mechanical properties. These steels found specialized scientific and industrial applications and were also favored by knife makers for the production of blades which are tough, hard and corrosion resistant.


History

The Crucible Steel Company of America was formed from the merger of thirteen crucible-steel companies in 1900. This, known as "the great consolidation of 1900", inspired other steel companies to form U.S. Steel a year later. From 1900 through the 20th century, Crucible developed and patented new steels, and brought new steel-production methods to the United States. C. H. Halcomb, Jr. was Crucible's first president and general manager. Two years later, he left Crucible, building the Halcomb Steel mill next door (where he installed the first electric-arc melting furnace in the U.S.). In 1911 Crucible acquired Halcomb Steel, merging the Halcomb plant with the new Sanderson plant to form the Sanderson-Halcomb Works. In 1955, it began producing vacuum-arc-remelted steels, becoming the first company to use this process commercially. By 1939, Crucible was the largest producer of

In 1946, the Sanderson and Halcomb steelworks were renamed the Sanderson-Halcomb Works, later becoming the Syracuse Works of Crucible Steel. In 1968, Crucible became Colt's Crucible Specialty Metals Division. Colt consolidated its basic-materials group into the Crucible Materials Corporation in 1983.


Founding companies

According to ExplorePAHistory.com, "By 1877, the region's fourteen medium-scale crucible steel factories produced nearly three-fourths of the nation's output. Metal-shaping factories across the country depended on cutting tools made of crucible steel through the 1920s, when electric steel furnaces gained prominence." Three companies which merged to form Crucible into the largest U.S. crucible-steel-producing company were: * ''Sanderson Brothers'' began producing steel in Sheffield, England in 1776. In 1873, it was using a gas-fired crucible melting furnace. Sanderson sold its Syracuse operation to Crucible, expanding its English company with the purchase of Samuel Newbould and Company. * Hussey, Wells and Company of

. Its partners were Curtis G. Hussey (who formed the Pittsburgh and Boston Mining Corporation to mine copper) and Thomas Marshall Howe (banker, investor, Congressman, assistant adjutant general of Pennsylvania and the first president of the Pittsburgh Chamber of Commerce. Thomas' son, George, helped form Crucible. Hussey and James M. Cooper formed C. G. Hussey and Company to roll and market copper. Before merging with Crucible, Hussey, Wells and Company became Howe, Brown and Company when George joined his father. * Park, Brother and Company of Pittsburgh, founded in 1860, was the second company to produce crucible steel in the U.S. James Park, Jr. and the elder David E. Park began the company after working with their father for twenty years. In 1857, James Jr. founded the Lake Superior Copper Works to sheath ship hulls. After encountering Hussey, Howe and Wells, he followed them into manufacturing crucible steel. Park built the Black Diamond (Park) Steel Works, and had interests in a suspension-bridge company and several banks. David's sons, David E. Jr., William G. and James H. Park, led in forming Crucible. In 1900, Park Steel was the largest producer of crucible and special-purpose open-hearth steels in the world. The other companies which formed Crucible were: * Aliquippa Steel Company, several miles north of Pittsburgh on the Ohio River * Anderson, DuPuy and Company * Beaver Falls Steel Works * Burgess Steel and Iron Works * Crescent Steel of Pittsburgh (founded 1865) * Cumberland Steel and Tin Plate Company * Isaac Jones' Pittsburgh Steel Works (later Anderson, Deputy and Company; founded 1845) * LaBelle Steel Company (formerly Reiter, Hartman and Company) of

Timeline

The following timeline provides references and events in the context of Crucible's history. Its primary source is the '' Syracuse Post-Standard'' archives, with other sources noted.


Sanderson Brothers and Company

''1776'': The Naylor and Sanderson Steel Mill was established in Sheffield, England, and began producing tool steel with the crucible method. By 1873 it was trading as Sanderson Brothers and Company, and using a gas-fired-crucible melting furnace. In 1876 Sanderson Brothers and Company bought Sweet Iron Works, which had been established in 1870 in Syracuse. Sheffield was known for its hard, durable steel, and Syracuse was known for its hard steel. Contemporary U.S. tariffs gave Sanderson an incentive for a U.S. operation. In 1878, Sanderson had $450,000 in capital and the following officers: Robert B. Campbell of New York, president; Samuel William Johnson of New York, secretary and William A. Sweet of Syracuse, general manager. In 1900, thirteen crucible-steel manufacturing companies formed the Crucible Steel Company of America. Sanderson divested itself of its American operation, offering 500,000 shares of stock for $50 million. Crucible's fifth annual report (published in 1905) showed debts of $3.6 million, $2.4 million less than the year before.


Halcomb Steel

In 1902 C. H. Halcomb Jr., Sanderson's president and general manager, left the company and built the Halcomb Steel mill next to the Sanderson mill. Halcomb installed the first

Hoyt-Noe Steel Company

By 1913, Thatcher Hoyt and Paul E. Noe formed the Hoyt-Noe Steel Company in Chicago. Hoyt had been representing crucible steels for twenty years; his previous companies included the Braeburn Steel Company, Singer, Nimick and Company and the Sanderson Brothers Steel Company.

mine. Now the company's chairman, Hufnagel brought in Raoul Eugene Desvernine as president. With a legal background, Desvernine focused on improving sales. The company had about 15,000 customers, net sales of $60 million and earnings of $4 million in 1937. The following year, Crucible lost $2 million as its sales halved during the recession of 1937–38. When Crucible sought to borrow money in 1940, the Mellon Security Corporation insisted on a full audit. This resulted in a $40 million revaluation of the company's property and plants (down to $81 million) and the loss of its fiscal surplus. On December 7, 1941, when the U.S. entered World War II, Syracuse was considered the Porretta Terme (Italy's gear-producing center) of America. In 1945 William P. Snyder Jr., president of Snyder Mining Company of Pittsburgh and a Crucible stockholder, brought in president William H. Colvin Jr. With the board's approval, Colvin closed four of the company's eleven operations and began a $46 million modernization. The Syracuse plants were consolidated in 1946 into the Sanderson-Halcomb Works. In 1949, Crucible began operations in an $18 million sheet and strip mill at the Midland works, becoming the first steel mill to use hot and cold rolling of stainless and high-alloy sheet and strip. Iron Age, manufacturer of the hot reversing mill, called this a transition from a curiosity to standard production practice; ovens on both sides of the rolls could better control the steel's temperature. When Crucible removed escape clauses from its employee contracts after the war, the company received approval from the United Steelworkers. During the 1950s, shortages of tungsten and vanadium caused by the wartime drive for cheaper alloying metals resulted in the development of AISI M2 high-speed steel. Colt Industries bought Crucible Steel Corporation of America in 1968, and the Syracuse works become Colt's Crucible Specialty Metals Division. In 1975, Crucible began marketing its products in the

. During the 1980s the AISI reported that more than 200,000 steelworkers in the U.S. had lost their jobs, and more than 400 mills and plant divisions were closing (including Crucible's Midland plant near Pittsburgh). Jones & Laughlin Steel bought the Midland plant and merged with Republic Steel to form the LTV Steel Corporation, which went bankrupt. In 1981 Colt moved the Crucible and Trent Tube Divisions to Syracuse from Pittsburgh, and the following year it began closing its Crucible Steel Plant (laying off 400 workers). In 1983 Colt Industries consolidated its basic-materials group into the Crucible Materials Corporation, with its headquarters in New York City. This was the last year that Crucible Specialty Metals negotiated union contracts without a strike. In 1984 Crucible manufactured the titanium alloy used in the

In 1988, Crucible Specialty Metals modernized its plant and the division employed 1,425 people worldwide. The Crucible Service Centers Division opened its Camillus, New York headquarters in 1989, marketing specialty steel products worldwide. That year, the workers struck; when a contract was signed, only 600 of 1,100 workers were called back to work. In 1991 Crucible Materials and

sued Crucible Materials Corporation over its pension plan for salaried employees. From 2001 to 2003, the corporation laid off 186 salaried and hourly workers on a rotating basis. CMC employed 1,209 workers, 722 union workers and 487 salaried workers in Geddes and its distribution center in Camillus. In 2004 Crucible Specialty Metals entered the knife market, moving its Camillus operation to the Geddes plant. The corporation filed for Chapter 11 bankruptcy in May 2009, and in October JP Industries (a private equity group in Cleveland) purchased the operating assets of the Crucible Specialty Metals Division and formed Crucible Industries. A month later, the Geddes steel mill was restarted. In 2010, Crucible partnered with Latrobe Specialty Steel Distribution to market its steels. According to Crucible president James Beckman, "Latrobe Distribution offers everything we wanted in a partner for our CPM grades of steel". Latrobe, with eight locations in North America, is a division of Latrobe Specialty Steel of Latrobe, Pennsylvania. That year Crucible partnered with Robert Zapp Werkstofftechnik, a division of the Zapp Group, to sell Crucible Particle Metallurgy products worldwide except for North America and Japan. In December 2024, Crucible Industries filed for Chapter 11 bankruptcy for the second time in 15 years. A number of Crucible's assets, including their inventories, intellectual property, and industrial equipment were purchased by Erasteel in February 2025.
