The supply of imported high quality SKH9 high speed steeland high wear resistance and high toughness of SKH9 high speed tool steel

SKH-9 specialty

The W-MO series (6-5-2) high speed tool steel is the mostcommon, especially SKH-9 (SKH51) is a lot of consumptionin the world, instead of on the W type high speed tool steel SKH2.

The carbide microstructure, neat, well distributed. But even organization. So the wear resistance and toughness is balanced. Especially as the only carbon content increases or decreases, so does not damage the high temperature characteristics, can be continuously and greatly change the steel properties. Low carbon steel for need toughness,hardness, wear resistance of under the condition ofsuitable for use in high carbon steel bell.

The rich hot work, cold plasticity, by cutting and grinding is also good.

SKH-9 uses

Cutting: drills, taps, reamers, circular saw, cutter, broach,cutter etc..

Die: all kinds of hot, cold die and punch, cutter, cutter,various gadolinium roller tools etc..

SKH-9 Japan Hitachi YSS Yasugi steel belongs to cold work tool steel is also called YXM1 tungsten amounted to more than 5.5% Japanese Hitachi SKH-9 special high quality die steel

Comparison of the standard and characteristics: M2chemical composition analysis results (%):

Steel characteristics: abrasion resistance, toughness, high speed steel

Steel for general use: suitable for manufacturing a powerful cutting wear, senior Heng die, die, than the required toughness and shape complicated tool, milling cutter, drilletc.

Factory state and hardness (surface): 255HB/60-64HRC

The process and characteristics of SKH-9 forging:

Forging: 1.100 ~ 900 ℃

Annealing: heating to 800-850 DEG C, the temperature fortwo to four hours, in the furnace as it is cold.

Quenching: pre heating to 550-600 Deg. C, heated to 950℃, and then heated to a:1220 ~ 1250 ℃; b:

1200 ℃ ~ 1230 ℃. In oil quenching,

But the oil must first moisturizing 40-60 ℃ (A. general tools;B. forms complex need resilience tools)

Tempering: heated to 550-570 DEG C, stay at this temperature, and then cooling in still air, tempering mustrepeat two times

Hardness: HRC63.

Use: This tungsten steel, high speed steel, suitable for manufacturing powerful cutting and abrasion resistance,impact resistance of various tools, advanced die, die,

Than the required toughness and shape complicated tool,milling cutter, drill etc..
