Why use this magnetic stainless steel?
Stainless steel grade 430 is a non-hardenable steel containing
straight chromium, and belongs to the ferritic group of steels.
All ferritic grades, such as stainless steel grade 430, have
excellent stress corrosion cracking resistance. Grade 430 has good
corrosion resistance to numerous substances, such as certain
organic acids and nitric acid.
Stainless steel grade 430 is capable of resisting oxidation up to
870°C (1598°F) in intermittent usage, and up to 815°C (1499°F) in
continuous usage. At room temperature, it has the tendency to
become brittle, especially when it has been heated for a long time
in the 400-600°C (752-1112°F) range. This issue can be overcome
with annealing.
For sub-critical annealing, heating should be performed to
760-815°C (1400-1499°F), followed by air-cooling or water
quenching.
This stainless steel cannot be hardened by thermal treatment.
