Martensitic Stainless Steel Properties Chart
Minimum mechanical properties of the standard martensitic stainless steels — 403 through 440C, including the free-machining and specialty types. Rows are grouped by type; each row gives a product form and condition with its tensile strength, yield strength, elongation, hardness and governing ASTM specification.

테이블 노트
Minimum mechanical properties for the standard martensitic stainless types, grouped by type — each row pairs a product form and condition with the properties guaranteed or typically expected in that condition. MPa and ksi columns are the same value in two units.
Hardness is given as Rockwell B, Rockwell C or Brinell exactly as printed (c) values are typical rather than guaranteed minimums. The spec column lists the ASTM specification each row is drawn from (A 276, A 473, A 479, A 580, A 581 and others).
In the source, one specification cell reads “A 276, 479”; it is read here as A 276, A 479.
Reference data for comparison — confirm the applicable specification and finish condition on the mill certificate before ordering or designing.
