Main Grades And Properties Of Austenitic Stainless Steel

Austenitic stainless steel mainly includes the following grades:

320HQ (0Cr18Ni9Cu3), SUS304 (0Cr18Ni9), 304M304J3 (304Hc), 316 (0Cr17Ni12M02), 316L (00Cr17Ni14M02).


Main steel characteristics:

302HQ: low carbon, low nitrogen, low sulfur, very low work hardening rate, excellent cold workability, suitable for complex shapes and difficult applications.

304: Moderate work hardening rate, suitable for general cold processing and drawing, and good cold working performance.

304M: Moderate work hardening rate, suitable for general cold processing and drawing.

304HC: The addition of copper to replace nickel reduces the work hardening rate of steel and maintains a low magnetic permeability.

SUS316: Add molybdenum, better pitting corrosion resistance. SUS316L: Substitute carbon, better corrosion resistance and better cold workability than 316.


The magnetic properties of the above materials are ranked from strong to weak: 304>304M>304HC>SUS316.
