Cr12MoV Steel | SKD11 alloy steel

Description

Cr12MoV steel is a kind of ledeburite cold work tool steel which developed from Cr12 steel, as the added content of Mo, V, and decrease of C, Cr12MoV have the advantage of Higher hardenability, hardness, wear resistance and small heat treatment distortion. It’s regularly be used in manufacturing cold mold with a heavy load, bulk production, and complex shape. Due to Cr12MoV is ledeburite steel, so its toughness is greatly influenced by the carbide morphology and distribution.

Cr12MoV Steel, steel hardenability, quenching and tempering the hardness, wear resistance and strength than that of high Cr12. Cross section used in the manufacture large, complex shape, working under arduous conditions, with a variety of Die and tools, such as die punching, trimming mold, piping die, deep drawing steel mold, circular saws, standards, tools and gauges, thread rolling die and so on.

Application

Cold work dies steel, steel hardenability, quenching, and tempering hardness, wear resistance, strength is higher than Cr12. Used in the manufacture of various cold stamping dies and tools with large cross- sections, complex shapes and heavy working conditions, such as punching die, trimming die, piping dies, deep drawing dies, circular saw, standard tools, and gauges Thread rolling die, etc.
