420J1 420J2 stainless hlau sawb
Lus piav qhia luv luv:
420J1 thiab 420J2 stainless hlau strips yog ob hom stainless hlau cov ntaub ntawv uas belongs rau martensitic stainless hlau series. Lawv muaj qee qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg thiab cov yam ntxwv. Nov yog ib lub ntsiab lus luv luv ntawm txhua tus:
1. 420J1 stainless hlau sawb: 420J1 yog ib qho tsis tshua muaj carbon stainless hlau nrog siab hardness thiab lub zog. Nws cov tshuaj muaj pes tsawg leeg feem ntau suav nrog 0.16-0.25% carbon, txog 1% chromium, thiab me me ntawm molybdenum. 420J1 muaj qhov zoo corrosion kuj, txiav kev ua tau zoo, thiab kev sib tsoo khoom. Nws feem ntau yog siv los ua riam, cov cuab yeej phais, cov khoom siv kho tshuab, thiab qee qhov kev siv hnav-tiv taus.
2. 420J2 stainless hlau sawb: 420J2 yog ib qho nruab nrab-carbon stainless hlau nrog siab hardness thiab hnav tsis kam. Nws cov tshuaj muaj pes tsawg leeg feem ntau muaj nyob ib ncig ntawm 0.26-0.35% carbon thiab txog 1% chromium. 420J2 muaj cov ntsiab lus carbon ntau dua piv rau 420J1, ua rau muaj zog ntxiv thiab txiav kev ua haujlwm. Nws yog feem ntau siv rau kev tsim riam, hniav, cov cuab yeej phais, qhov chaw, thiab qee qhov chaw siv tshuab.
