Qib 420 Stainless Hlau

Kev piav qhia

Qib 420 yog qib siab -carbon martensitic stainless hlau, muab lub zog siab dua, hardness, thiab hnav tsis kam tshaj qib 410 vim nws cov ntsiab lus carbon ntau ntxiv (0.15-0.30%). Nws muaj 12.0-14.0% chromium, muab kev tiv thaiv corrosion zoo dua li 410, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig me me mus rau nruab nrab corrosive. Zoo li lwm cov qib martensitic, 420 yog sib nqus thiab tuaj yeem kho cua sov (quenched thiab tempered) kom ua tiav cov khoom siv zoo heev, suav nrog cov hardness siab thiab toughness. Nws muaj qhov nruab nrab weldability, tab sis kev kho cua sov tom qab vuam yog tsim nyog los tswj nws cov corrosion kuj thiab txo brittleness . 420 yog siv dav hauv cov ntawv thov uas yuav tsum muaj ob qho tib si hnav tsis kam thiab corrosion kuj, xws li cov cuab yeej txiav, cov cuab yeej kho mob, thiab cov khoom lag luam. Nws muaj peev xwm yuav polished mus rau lub siab tiav kuj ua rau nws haum rau cov hniav thiab aesthetic daim ntaub ntawv.

Qhov zoo

Siab hardness thiab hnav tsis kam tshaj 410; corrosion kuj zoo dua 410; tshav kub- kho tau rau kev ua tau zoo dua; Sib nqus; tuaj yeem polished rau qhov ua tiav siab; haum rau daim ntawv thov uas yuav tsum tau muaj zog thiab corrosion kuj.

Daim ntawv thov

Riam, hniav, cov cuab yeej phais, cutlery, pwm qhov chaw, li qub, twj tso kua mis, lub zog, thiab cov khoom uas yuav tsum tau muaj kev hnav tsis kam thiab nruab nrab corrosion kuj.

Qib sib npaug
