SKD61 Tool Steel

SKD61 yog cov neeg sawv cev siv dav hlau hauv kev ua haujlwm kub tuag steel, uas tuaj yeem siv los tsim cov forging tuag, kub extrusion tuag thiab precision forging tuag nrog cov khoom loj. Aluminium, tooj liab thiab lawv cov alloys tuag casting. Nyob rau tib lub sijhawm, vim nws cov ntsiab lus vanadium siab dua, nws qhov kev ua tau zoo ntawm qhov nruab nrab kub (600 degree) zoo dua li SKD6 alloy hlau, uas tuaj yeem siv los ua cov khoom tseem ceeb hauv kev lag luam aviation.

Cov khoom xyaw tseem ceeb (%):

Cov pa roj carbon (C) {{0}}.35 ~ 0.42

Silicon (Si) 0.80 ~ 1.20

Manganese (Mn) {0}}.25 ~ 0.50

Phosphorus (P) Tsawg dua lossis sib npaug rau 0.030

Sulfur (S) Tsawg dua lossis sib npaug rau 0.020

Chromium (Cr) 4.80 ~ 5.50

Molybdenum (Mo)1.00 ~ 1.50

Vanadium (V) 0.80 ~ 1.15

Kev kho cua sov txheej txheem specification thiab kev ua tau zoo:

Kev kho cua sov txheej txheem specification: quenching, (790 ± 15) degree preheating, (1000 ± 6) degree (ntsev da dej) los yog (1010 ± 6) degree (kub tswj cua) cua sov, tuav 5-15min, cua txias, (550 ± 6) degree tempering.

Mechanical zog: 820 ~ 870 degree qeeb txias annealing, annealing hardness Tsawg dua los yog sib npaug rau 229HB; Qauv quenching hardness Ntau dua los yog sib npaug rau 50HRC.

SKD61 yog cov cuab yeej siv hlau, cua hardening kub ua haujlwm tuag steel, yog tam sim no siv dav thiab yog ib qho ntawm cov neeg sawv cev tshaj plaws kub ua haujlwm tuag steel, nws cov yam ntxwv tseem ceeb yog: 1) muaj zog hardenability thiab siab toughness; 2) Cov thermal tawg zoo heev, tuaj yeem ua dej txias hauv chaw ua haujlwm; 3) Nrog rau nruab nrab hnav tsis kam, cov txheej txheem carburizing lossis nitriding tuaj yeem siv los txhim kho qhov tawv tawv, tab sis me ntsis kom txo cov thermal cracking kuj; 4) Vim nws cov ntsiab lus tsis tshua muaj carbon, lub peev xwm thib ob hardening hauv tempering tsis zoo; 5) Nws muaj peev xwm tiv taus softening ntawm qhov kub thiab txias, tab sis lub hardness yuav txo tau sai heev thaum kub siab tshaj 540 degree C (1000 degree F) (uas yog, lub peev xwm ua hauj lwm kub yog 540 ° C); 6) Lub deformation ntawm kev kho cua sov yog me me; 7) Nruab nrab thiab siab machinability; 8) Nruab nrab tsis kam mus decarbonization.
