ASTM Stainless Steel Drawn Wire Rods A493 AISI 431 UNS S43100
ASTM A493 AISI 431 UNS S43100 Stainless Steel Drawn Wire And Wire Rods
Grade 431 is a nickel bearing stainless chromium steel which can be treated to exceptionally
high physical properties. In the heat treated conditions, its corrosion resistance is superior to
similar martensitic types. Stainless 431 is a high chromium, low nickel, martensitic stainless steel.
Type 431 stainless steel can be hardened through heat treatment processes.
431 stainless Provides improved corrosion resistance and toughness (impact strength) in a
quench-hardenable stainless steel. 431 stainless has been used for fasteners and fittings, structural
components exposed to marine atmosphere, and for highly stressed aircraft components.
