We produce steel solids to a range of quality levels, including commercial, electric furnace, aircraft, bearing quality steel, and Parapremium steel.
Steels are typically produced to AISI standards, but we also melt non-standard steels produced to customer specifications.
Much of our special quality production goes into aircraft, anti-friction bearings, gun quality steel, missiles and steel with high transverse mechanical properties.
Aircraft
This quality level of steel is produced in accordance with the industry specification AMS 2301. It is generally used for important or highly stressed aircraft parts. It is also used in other applications involving additional stringent requirements such as magnetic particle inspection and macroetch limits. Exacting steelmaking, rolling and testing practices are employed to meet these requirements.
Bearing
Bearing quality generally applies to alloy steel bars and tubes intended for the manufacture of anti-friction bearings. This quality level is usually produced from standard alloy carburizing grades and high-carbon chromium grades.
These steels are produced in accordance with ASTM A 534, A 295, and A 485. Bearing quality steels are subjected to restricted melting and special teeming, heating, rolling and conditioning practices to meet the rigid quality requirements.
Commercial
Commercial quality refers to the basic or standard quality level for alloy steel bars and tubes. It is generally used for less critical applications.
This quality level of steel is melted to chemical ranges and limits, and inspected and tested to meet normal requirements for regular constructional alloy steel applications.
Parapremium™ (AMS 2304)
This quality level of steel is produced in accordance with industry specification AMS 2304. It is generally used for extremely critical or highly stressed parts. It is also used in other applications involving additional exceptionally stringent requirements such as magnetic particle inspection and macroetch limits.
To meet these requirements, exacting steelmaking, rolling and testing practices are employed.
Electric Furnace Quality
Our primary melting vessel is an electric-arc furnace. Steel scrap is melted by passing electricity through carbon electrodes. The primary advantage of this type of furnace is it permits the extremely close control of temperature, heat analysis, and refining conditions required in the production of standard carbon and alloy steels. Electric furnace quality refers to a restriction of .025 percent maximum sulfur content and .025 percent maximum phosphorous content for the grade specified.
