Stainless Steel Alloy 15-5 PH Bar

Specialist supplier of stainless steel 15-5 PH round bar. It can be supplied in a range of sizes and finishes with varying tolerances. Cold-finished stainless steel bar is usually supplied to meet the international standards of ASTM A276/A484 or A582/A484M.

Stainless Steel Alloy 15-5 PH 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, Stainless Steel Alloy 15-5 PH Bar 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.

Alloy 15-5 PH 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.

Applications

Aerospace – piston engine manifolds
Chemical Processing
Expansion Joints
Food Processing – equipment and storage
Petroleum Refining – polythionic acid service
Waste Treatment – thermal oxidizers

Benefits

Higher creep stress and rupture properties when compared with 304
Ideal for high temperature service
Overcomes sensitization and intergranular corrosion concerns
Can be used in elevated temperature applications for ASME Boiler and Pressure Vessel Code applications
Due to stabilisation the material offers better overall corrosion resistance when compared to 304/304L
Excellent mechanical properties
