Description

A kind of mold special steel
Technical field
The present invention relates to field of alloy steel more particularly to a kind of mold special steels.
Background technique
Steel alloy is nation-building and essential valuable cargo of realizing the four modernizations, and is widely used, is various in style, according to disconnected The difference of face shape, steel are generally divided into profile, four major class of plate, tubing and metal product, for the ease of organizing the life of steel It produces, order goods and supply and do management and administration well, and be divided into heavy rail, light rail, heavy section steel, medium shape, light section, steel Cold-rolled forming section, high-quality shaped steel, wire rod, medium plate, sheet metal, electrician's silicon steel sheet, strip, seamless steel pipe steel, welding steel The kinds such as pipe, metal product.
Mold the processes such as beats for metal or the punching of nonmetallic materials, stretching, bending, extruding, upsetting.Mould steel requires to have Enough intensity, toughness, hardness, abrasion-resistance, anti-fatigue ability, resistance to deformation, Resisting fractre ability.Currently, mold materials market On the die steel material that is most widely used be high carbon and chromium mould steel.
Chinese Patent Application No.: 201711264677.6, a kind of high strength steel formula is disclosed, the raw material in formula is by weight Amount percentage composition is respectively: molybdenum 75-85%, manganese 1-5%, aluminium 1-10%, nitrogen 5-15%, iron 3-9%, carbon 3-5%.
Foregoing invention creates its intensity, hardness generally readily satisfies, but toughness is lower, is not able to satisfy machining needs.
