Alloy 254 Bar is a molybdenum-bearing austenitic stainless steel with greatly increased resistance to chemical attack as compared to the conventional chromium-nickel austenitic stainless steels such as Alloy 304. In addition, Alloy 440 offers higher creep, stress-to-rupture, and tensile strength at elevated temperatures than conventional stainless steels. It is a low carbon or "L" grade which provides resistance to sensitization during welding and other thermal processes.
Carey Alloys Metal is is a stock a full range of stainless round bars from 8mm diameter to 600 mm forged bars with 4 meters to 6 meters length. Nearly all grades of stainless steel are stocked in round bar, including 302, 303, 304/L, 304H, 309/S, 310/S,316/L,317/L, 321, 321/H, 347, 347H, 410, 416, 420, 440C,17-4PH,Duplex 2205 and Alloy 20. We manufacture products such as Steel Rounds, Squares, Hexagons, RCS and Bright Bars of various grades which are used as raw material by various manufacturers of Engineering, Forging, Bright Bars, Auto Components goods.
Alloy 254 Bar is a titanium stabilized austenitic stainless steel with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 – 1500°F (427 – 816°C). The alloy resists oxidation to 1500°F (816°C) and has higher creep and stress rupture properties than alloys 304 and 304L. It also possesses good low temperature toughness. It was developed for enhanced creep resistance and for higher strength at temperatures above 1000oF (537°C). In most instances, the carbon content of the plate enables dual certification.
