d5 — elongation at break
HB — Hardness Brinell.
Corrosion resistance
Initially, the alloy was created for use in industrial chemistry. It is more resistant to corrosion in aggressive industrial environments than other steels, are not susceptible to crevice corrosion and stress corrosion cracking. Part of the molybdenum ensures resistance to pitting and crevice corrosion.Percentage composition GOST 5632−72
