203L thiab 420J1H yog ob hom hlau nrog cov yam ntxwv tshwj xeeb.
203L steel yog ib tug tsawg-nickel, high-manganese austenitic stainless hlau uas muaj superior durability thiab corrosion kuj. Nws yog feem ntau siv rau hauv cov ntawv thov uas xav tau lub zog siab thiab tiv thaiv xeb, xws li cov khoom siv hauv hiav txwv, cov chaw ua tshuaj lom neeg, thiab cov tshuab ua zaub mov. Lub 203L steel qhov kev tiv thaiv corrosion yog txhim kho los ntawm nws cov ntsiab lus carbon tsawg, uas tiv thaiv carbide nag lossis daus hauv thaj chaw tshav kub. Qhov no txhais tau hais tias nws tseem nyob ruaj khov nyob rau hauv ib puag ncig uas muaj kev cuam tshuam rau acidic lossis ntsev.

Ntawm qhov tod tes, 420J1H stainless hlau yog cov tawv tawv thiab tempered stainless hlau nrog cov ntsiab lus siab carbon, uas ua rau nws tiv taus hnav thiab puas. Nws feem ntau yog siv rau cov cuab yeej txiav, pob bearings, thiab cov cuab yeej phais. Cov hlau cov ntsiab lus siab carbon muab nws lub zog siab thiab hardness, ntxiv rau nws cov kav ntev. 420J1H steel kuj muaj kev tiv thaiv corrosion zoo heev thiab tuaj yeem tiv taus ib puag ncig hnyav, ua rau nws tsim nyog siv rau hauv cov khoom siv hauv hiav txwv thiab lwm yam kev siv uas yuav tsum muaj kev tiv thaiv xeb.
Hauv kev xaus, ob qho tib si 203L thiab 420J1H steel muaj cov yam ntxwv tshwj xeeb uas ua rau lawv haum rau kev siv sib txawv. 203L steel paub txog nws cov kev tiv thaiv corrosion zoo heev, thaum lub 420J1H steel yog qhov ruaj khov thiab hnav-tiv taus. Lawv cov cwj pwm zoo ua rau lawv nrhiav tau zoo heev thiab tseem ceeb hauv kev tsim khoom ntawm ntau yam khoom.
