Product Details
Alloy 321 (UNS S32100) 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.
Alloy 321H (UNS S 32109) is the higher carbon (0.04 – 0.10) version of the alloy. 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.
Alloy 321 cannot be hardened by heat treatment, only by cold working. It can be easily welded and processed by standard shop fabrication practices.
Shape: Round, Square, Rectangular, Hexagonal, Slot, Oval, etc
Outer Diameter:
Round pipe: 8mm to 680mm
Square pipe: 10x10mm to 300x300mm
Rectangular pipe: 10x20mm to 120x180mm
Thickness:
Seamless pipe: 0.6mm – 30mm
Welded pipe: 0.5mm – 25mm
Application: Decoration, construction, upholstery, industry instrument, medical equipment, seawater environment, petrochemical, fertilizer, oil refining, oil and natural gas, light/food, paper pulp and making paper, energy and environmental protection industry, ect
