Cov khoom lays lub hauv paus, thaum tshav kub kev kho mob txiav txim hardness, toughness thiab kev pab cuam lub neej; tsuas yog thaum ob qho tib si zoo sib xws tuaj yeem ua rau cov nyhuv txiav.
I. Cov Khoom Siv (Cov Ntsiab Lus Tseem Ceeb)
1,65mn: ua.Tus nqi qis, zoo toughness, haum rau tsawg- ceev txiav ntawm cov ntaub ntawv mos (daim ntawv, zaj duab xis), tsis zoo liab hardness
2.SK5/T8 ~ T10:Siab hardness, nruab nrab nqi, rau nruab nrab nruab nrab - mus rau - tsawg ceev txiav, tsis tshua muaj kev cuam tshuam
3.9 TSI:Balanced hnav tsis kam thiab toughness, mainstream economical hom, haum rau ntev hniav, transverse / longitudinal txiav hniav
4.Cr12/Cr12MoV:High hardness thiab hnav tsis kam, me me deformation, sab saum toj xaiv rau siab - kawg daim ntaub ntawv, haum rau siab - ceev txiav cov tuab zaj duab xis / aluminium foils
5. SKD11/DC53:High hardness thiab siab toughness, siab -kawg lwm txoj rau cov ntaub ntawv txawv teb chaws, haum rau siab - ceev thiab siab - precision txiav
6.High -Speed Steel (M2):Cov tawv tawv liab zoo heev, rau ultra-siab- txiav ceev, tus nqi siab
Cemented Carbide: hnav heev-resistant (kev pab lub neej 10 ~ 30 npaug ntawm cov hlau zoo tib yam), haum rau cov khoom siv abrasive, nkig thiab kim
II. Core Heat Treatment (Yooj yim)
1. Kev sib tw:Yooj yim rau kev ua thiab txo cov kev ntxhov siab sab hauv
2.Quenching:Cua sov (800 ~ 1050 degree) + roj txias / cua txias los txhim kho hardness thiab hnav tsis kam
3. Tempering:Tsawg kub khaws cia hardness thiab txo brittleness; nruab nrab kub txhim kho toughness rau kev ua tau zoo
Cryogenic kev kho mob (-70 ~ -196 degree): Qhov tseem ceeb rau cov riam high-end, stabilizes qhov ntev, boosts hardness thiab hnav tsis kam
4.Fine sib tsoo:Xyuas kom meej thiab ntse txiav ntug
III. Core Xov Xwm
●65Mn/SK5:quenching + Tsawg-kub Tempering (HRC58-62)
●9CrSi:Quenching + Tempering (HRC60-63)
●Cr12MoV/SKD11/DC53:quenching + Cryogenic kho + Tempering (HRC61-65)
●High -Speed Steel:Siab -kub Quenching + Ntau Temperings (HRC64-67)
● Cemented Carbide:Hmoov Sintering (HRC80-90)
