CrWMn kub dov steel puag ncig tuav

CrWMn tuag steel phaj yog alloy cuab yeej hlau, roj quenching tsawg deformation txias ua hauj lwm tuag steel.The steel wearability, vim koom nrog cov loj feem ntawm 1.20% ~ 1.60% tungsten, daim ntawv carbides yog li tom qab quenching thiab tsis kub kom muaj ⼀hardness thiab tungsten pab ua kom cov nplej zoo los ntawm kev ua cov hlau ntau dua.Cov hlau yog rhiab rau cov pa roj carbon monoxide, uas tuaj yeem ua rau cov hniav tuaj yeem ua rau spilling.Txawm hais tias lub zog, hardness thiab toughness ntawm cov hlau yog siab dua li carbon steel, Nws muaj qhov tsis xws luag xws li tawg yooj yim thiab sib tsoo tawg vim yog carbide kev sib cais.Lub quenching nyhav rau cov pa roj carbon steel, thiab cov ntawv thov ntau yog txo.Qhov hardenability thiab abrasion kuj ntawm cov hlau nrog rau cov hardness ntawm chromium hlau thiab chromium silicon steel tom qab. quenching yog zoo, thiab lub toughness yog zoo.
CrWMn feem ntau yog siv rau cov cuab yeej carbon steel tsis tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm qhov loj hla ntu, ntau qhov zoo ntawm cov khoom tuag, yuav tsum muaj tsawg dua quenching deformation.
1) Cov hlau no tau siv dav hauv kev ua cov hlau nyias, cov hlau tsis muaj hlau, cov khoom siv yooj yim ntawm lub teeb thauj khoom thiab cov duab zoo nkauj txias stamping tuag, tshwj xeeb tshaj yog nyob rau hauv lub moos, ntsuas, khoom ua si thiab khoom lag luam, thiab lwm yam. hedging austenite steel phaj, silicon steel ntawv thiab siab zog steel phaj tsis zoo tagnrho.

2) lub thickness ntawm cov hlau yuav siv tau los ua cov khoom <1 hli ntawm blanking tuag complex zoo li punch, concave tuag, teem piece, thiab intensive ⼀ strands ntawm sib sib zog nqus nqus tuag. Punch ntau lawm pom zoo 58 mus rau 62 HRC hardness, thiab lub concave pwm ntau lawm qhia tias hardness 60 ~ 64 HRC.

3) Nws yog siv rau kev ntxig ntawm punch tuag nrog siab hnav tsis kam thiab cov duab nyuaj hauv dabtsi yog khoov tuag. Lub hardness ntawm punch tuag yog pom zoo kom yog 58 ~ 62HRC thiab 60-64hrc yog pom zoo kom 60-64hrc thaum ua cov punch tuag

4) Convex tuag thiab concave tuag rau txias extrusion tuag ntawm txhuas qhov chaw.Qhov hardness ntawm 60 ~ 62HRC yog pom zoo rau cov punch tuag thiab 62 ~ 64HRC yog pom zoo rau punch tuag.

5) Rau txias extrusion tuag ntawm tooj liab qhov chaw thiab txias extrusion tuag thiab tuag ntawm steel qhov chaw, qhov pom zoo hardness yog 62-64hrc.

6) Tom qab forged, nws tuaj yeem siv los ua cov pwm loj veneer uas siv rau ntawm cov tshuab siab ntau dua 1 hli, feem ntau ua rau cov hlau hardness nce mus txog 50-55hrc. Txawm li cas los xij, pom tseeb cov ntaub so ntswg tsis xws li cov qauv banded carbide lossis kua chromatography yuav tsum raug txo lossis zam.
