420J1 420J2 stainless hlau sawb
Kev Piav Qhia Luv:
420J1 thiab 420J2 stainless hlau strips yog ob hom stainless hlau uas feem ntau yog cov martensitic stainless hlau series. Lawv muaj qee qhov sib txawv hauv cov tshuaj lom neeg thiab cov yam ntxwv. Nov yog cov lus piav qhia luv luv ntawm txhua tus:
1. 420J1 stainless hlau strip: 420J1 yog cov hlau stainless hlau uas muaj cov pa roj carbon tsawg uas muaj qhov tawv thiab lub zog siab. Nws cov tshuaj lom neeg feem ntau muaj li ntawm 0.16-0.25% carbon, li ntawm 1% chromium, thiab me me ntawm molybdenum. 420J1 muaj kev tiv thaiv corrosion zoo, kev ua haujlwm txiav, thiab kev sib tsoo zoo. Nws feem ntau yog siv rau kev ua riam, cov cuab yeej phais, cov khoom siv kho tshuab, thiab qee qhov kev siv uas tsis yooj yim hnav.
2. 420J2 stainless hlau strip: 420J2 yog cov hlau stainless hlau nruab nrab-carbon nrog lub zog siab thiab hnav tsis kam. Nws cov tshuaj lom neeg feem ntau muaj li ntawm 0.26-0.35% carbon thiab li ntawm 1% chromium. 420J2 muaj cov pa roj carbon ntau dua piv rau 420J1, ua rau muaj kev tawv thiab kev txiav zoo dua. Nws feem ntau siv rau kev tsim riam, hniav, cov cuab yeej phais, lub caij nplooj ntoos hlav, thiab qee qhov khoom siv kho tshuab.
