ѕc - Ultimate short-term strength

sT - Limit of proportionality (yield strength for permanent deformation)

d5 - Tensile elongation at break

HB - Brinell hardness.

Corrosion resistance

The alloy was originally developed for use in industrial chemistry. It is more resistant to corrosion in aggressive industrial environments than other steels and is not prone to crevice corrosion and corrosion cracking. The molybdenum in the composition guarantees resistance to pitting and crevice corrosion.
