T 20878 022Cr19Ni10

Equivalent Standards

ASTM 304L / GB 022Cr19Ni10

Equivalent Grades

Solution anneal 1010–1150 °C followed by rapid water quench to retain austenite; not hardenable by heat treatment. Sensitization avoided by low carbon or stabilizers (Ti/Nb).

Applications

低碳304，焊接后抗晶间腐蚀。,"Plate

Available Forms

Sheet

Uses

Bar

Heat Treatment

Tube"

Precautions

Austenitic stainless steel with excellent corrosion resistance, formability and weldability; non-magnetic in annealed condition. High nickel (≈10%) stabilises the austenite and improves toughness and pitting resistance. Used in food processing, chemical plant, architecture, heat exchangers, kitchenware and medical devices.
