High speed steel ntawm muaj nplooj pu

Kev kub ceev (HSS) yog ib lub cav hlau uas muaj kev kub ntxhov, kev sib zog ua haujlwm thiab kev kub kub. Kev kub ceev muaj zoo kev ua tau zoo thiab zoo zog thiab toughness, yog li nws yog siv los ua txoj siv nyias cov hniav thiab tej yam tawv hlau tiv thaiv cov cuab yeej siv, thiab cov kub thiab txias extrusion tuag. Hauv kev tsim ntawm peb cov hniav tuaj yeem, cov neeg siv ceev ceev yog siv, xws li Guillotine riam rau ntawv cutter, txha caj dab, lub pob riam ... Ob qhov khoom HSS nrov yog W18Cr4V, W6Mo5Cr4V2, thiab W18Cr4V yog tib neeg feem ntau xaiv guillotine riam rau ntawv cutter.

Cov khoom lag luam ntawm W18Cr4V:

C: 0.7-0.8; Cr: 3.8-4.4; W: 17.5-19.0; V: 1.0-1.4; Mo≤0.30; Mn <> Si <> S≤0.03; P≤0.03

Hardness ntawm W18Cr4V: 66-68HRC
