JIS Phil Pan Head Screws A2 Stainless Steel

JIS Phil Pan A2 Stainless

SUS304 (A2)
With Mo (molybdenum) added, which has good corrosion resistance.
In addition, corrosion resistance is improved by increasing the amount of Ni (8% for 304).
SUSXM7 (A2)
Stainless steel that is easier to process than SUS304.
　Cr18% + Ni9% + Cu3%
Cu (copper), a soft metal, is added to SUS304, which does not have good cold workability, to suppress work hardening and make it easier to cold work.
Corrosion resistance and strength are equivalent to SUS304.

SUS316 (A4)
Stainless steel has particularly good corrosion resistance among austenitic stainless steels.
　Cr18% + Ni12% + Mo2%
