420J1 420J1 420J2 4T2 Stainless Hlau Sawb
Cov lus piav qhia luv luv:
420J1 thiab 420j2 thiab 420J2 stainless hlau stips yog ob hom stainless hlau cov ntaub ntawv uas yog cov martensitic stainless hlau series. Lawv muaj qee qhov sib txawv ntawm cov tshuaj lom neeg thiab cov yam ntxwv. Ntawm no yog cov lus qhia luv luv ntawm txhua tus:
1. 420j1 Stainless Hlau Sawb: 420J1 yog cov hlau roj carless cov hlau uas muaj zog hnyav thiab muaj zog. Nws cov tshuaj lom neeg muaj pes tsawg zaus suav nrog 0.16-0.25% carbon, txog 1% chromium, thiab me me ntawm molybdenum. 420J1 muaj cov tshuaj tiv thaiv zoo, txiav kev ua haujlwm, thiab kev sib tsoo cov khoom. Nws yog feem ntau siv rau kev ua kom riam, kev phais cov twj paj nruag, cov tshuab siv tshuab, thiab qee cov khoom siv uas tiv thaiv.
2. 420j2 Stainless Hlau Sawb: 420J2 yog ib qho nruab nrab-carbon stainless hlau nrog lub siab tawv thiab hnav tsis kam. Nws cov tshuaj lom neeg muaj pes tsawg leeg feem ntau muaj nyob ib ncig 0.26-0.35% carbon thiab txog 1% chromium. 420J2 muaj cov ntsiab lus muaj roj carbon ntau dua piv rau 420j1, ua rau muaj kev ua kom muaj zog ntxiv thiab txiav kev ua haujlwm. Nws yog feem ntau siv rau kev tsim khoom riam, txuas, phais cov twj, caij ntoo, thiab qee qhov chaw siv tshuab.
