3Cr13 steel yog martensitic stainless hlau nrog cov ntsiab lus carbon ntawm (0.26%) mus rau 0.35% thiab cov ntsiab lus chromium ntawm (12.00%) txog 14.00%. Nws muaj lub zog siab thiab hnav tsis kam, thiab tom qab kev kho cua sov, nws yog qhov zoo tagnrho rau kev tsim cov khoom siv tshuab uas xav tau cov khoom siv tshuab siab. Cov hlau no tsuas yog siv rau hauv kev tsim cov riam (xws li cutlery thiab scalpels), springs, li qub, bearings thiab cov cuab yeej kho mob.
3Cr13 steel sib npaug yog dab tsi?
Lub ntsiab sib npaug ntawm 3Cr13 steel yog 420 (US), X30Cr13 (EU) thiab SUS420J2 (Nyiv). Cov qhab nia no raug suav tias sib piv vim lawv cov khoom sib xws thiab cov khoom sib xws, txawm hais tias qhov sib txawv me me tuaj yeem tshwm sim nyob ntawm cov qauv tshwj xeeb hauv cheeb tsam thiab kev tswj kom zoo.

Kev kho cua sov
Annealing: Cov hlau yog rhuab mus txog 800-900℃thiab maj mam txias. Qhov no softens nws, ua rau nws yooj yim rau tshuab thiab tshuab.
Quenching: Rau quenching, nws yog rhuab mus rau 920-980℃thiab ces txias sai sai hauv roj los yog cua. Qhov no tsim cov qauv nyuaj martensitic.
Tempering: Tom qab tempering, cov hlau yog nkig. Tom qab ntawd nws yog rhuab mus rau qhov kub thiab txias (feem ntau yog 150 mus rau 350 degrees) thiab tuav nyob rau ntawd ib pliag kom txo brittleness thiab nce toughness.
Yog 3Cr13 magnetic?
3Cr13 yog martensitic stainless hlau, thiab nws cov qauv siv lead ua (martensite) yog ferromagnetic. Tsis zoo li austenitic stainless hlau xws li 304 lossis 316, 3Cr13 yog sib nqus nyob rau hauv ob qho tib si annealed thiab hardened xeev.
3Cr13 steel siv rau dab tsi? 3Cr13 steel yog ib qho kev lag luam martensitic stainless hlau, zoo tagnrho rau cov ntawv thov uas yuav tsum tau muaj qhov sib npaug ntawm lub zog, hnav tsis kam thiab nruab nrab corrosion kuj. Nws yog feem ntau siv rau kev tsim cov riam uas pheej yig, txiab, thiab cov cuab yeej yooj yim, nrog rau cov khoom lag luam xws li axles, bolts, thiab li qub. Nws lub ntsiab zoo yog nws cov hardness siab (54-56 HRC) thiab nws yooj yim ntawm sharpening, thaum nws lub ntsiab tsis zoo yog nws txwv ntug tuav thiab nruab nrab toughness piv rau high-end steels.
3Cr13 Hlau vs 440C stainless hlau
440C los yog 3Cr13? 440C muab cov hardness zoo dua, hnav tsis kam thiab ntug tuav. Siv rau kev ua haujlwm tseem ceeb. Xaiv 3Cr13 rau cov cuab yeej siv nyiaj txiag nrog kev ua haujlwm nruab nrab.
Yog tias koj xav tau 420 stainless hlau tuav rau koj qhov project, thov koj xav tso qhov kev txiav txim. GNEE muaj cov khoom muag loj ntawm cov khoom nrov rau koj xaiv.
