Martensite stainless steel SUS431

Stainless steel SUS431 equal material: AISI431, ASTM 431, UNS S43100, X17CrNi16-2, 1.4057.

Stainless steel SUS431 comprehensive description
Stainless steel SUS431 won't produce corrosion, pitting, corrosion or wear and tear. Stainless steel or building one of the highest strength of metal materials in the material. Because the stainless steel has good corrosion resistance, so it can make structure parts permanently maintain the integrity of engineering design. Chromium stainless steel also has high mechanical strength and extensibility, easy processing and manufacturing of parts and can meet the needs of architects and structural designers.
