Khoom Description
M42 steel yog siab cobalt toughness high-speed steel, qhov loj feem ntawm vanadium nyob rau hauv M42 steel tsis siab (li 1%), qhov loj feem ntawm cobalt yog siab (li 8%), cobalt yuav txhawb carbide nyob rau hauv lub quenching cua sov ntau. yaj hauv matrix, kev siv cov matrix siab hardness los txhim kho hnav tsis kam. Lub hardness, thermal hardness, hnav tsis kam thiab grindability ntawm steel yog zoo heev.
Cov khoom xyaw tseem ceeb (%):
Cov pa roj carbon (C) 1.05 ~ 1.15
Manganese (Mn) {0}}.15 ~ 0.40
Silicon (Si) {{0}}.15 ~ 0.65
Phosphorus (P) Tsawg dua lossis sib npaug rau 0.030
Sulfur (S) Tsawg dua lossis sib npaug rau 0.030
Chromium (Cr) 3.50 ~ 4.25
Vanadium (V) 0.95 ~ 1.35
Tungsten (W) 1.15 ~ 1.85
Molybdenum (Mo) 9.00 ~ 10.00
Cobalt (Co) 7.75 ~ 8.75
Kev kho cua sov txheej txheem specification thiab kev ua haujlwm
Kev kho cua sov txheej txheem specification: quenching, 730 ~ 845 degree preheating, 1190 ~ 1210 degree (kub da dej rauv) los yog 1200 ~ 1220 degree (lub thawv rauv) cua sov, roj txias, 540 ~ 560 degree tempering ob zaug, txhua 2h.
Mechanical zog: annealing hardness Tsawg dua los yog sib npaug rau 269HBW, txias drawing annealing hardness Tsawg dua los yog sib npaug rau 277HBW, txias drawing hardness Tsawg dua los yog sib npaug rau 285HBW.
Thaum tshav kub kub kho hardness tuaj yeem ncav cuag 67-70HRC, tab sis kuj tseem muaj cov kev kho cua sov tshwj xeeb kom tau txais qhov tawv ntawm 67-68HRC, kom nws cov kev ua tau zoo (tshwj xeeb yog txiav tsis tu ncua) txhim kho, txhim kho qhov cuam tshuam toughness. Cov hlau tuaj yeem ua rau ntau yam cuab yeej, txiav nyuaj rau kev ua cov ntaub ntawv thaum cov nyhuv zoo heev, nrog rau cov hlau tsim cov cuab yeej txiav, tuaj yeem txiav hlau raws li superalloy, cam khwb cia superalloy, titanium alloy thiab ultra-siab zog steel, tab sis toughness yog me ntsis tsis zoo, quenching kub siv qhov kev txwv qis. Vim tias cov hlau muaj kev sib tsoo zoo, nws tuaj yeem ua rau ntau yam khoom siv high-precision complex.
