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.
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.
Solution annealing can be performed by heating stainless steel grade 430 to 815 – 845°C (1499-1553°F). Then it has to be slow furnace cooled to 600°C (1112°F) and followed by air-cooling in a quick manner – as slow cooling between 540 and 400°C (1004 and 752°F) tends to cause embrittlement.
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.
