Q420D HSLA Steel Phaj
Q420D High-Strength Low Alloy (HSLA) Hlau PhajKhoom Description
Q420D alloy steel daim ntawv yog cov hlau tsis tshua muaj siab lub zog steel nrog zoo kub tsis tshua muaj kev cuam tshuam toughness, uas tuaj yeem ua tau raws li koj qhov tshwj xeeb engineering xav tau.
Q420D hsla cov qauv hlau muaj cov yas zoo thiab cov khoom ua haujlwm, thiab yooj yim rau kev txiav, khoov, stamp thiab lwm yam kev ua haujlwm. Nyob rau tib lub sijhawm, Q420D siab zog qis alloy steel kuj muaj qee yam corrosion kuj thiab kav ntev, thiab kev ua tau zoo tuaj yeem txhim kho los ntawm kev ntxiv cov ntsiab lus alloy thiab kev kho deg.
Q420D cov hlau tsis tshua muaj hlau tuaj yeem siv rau hauv cov tsev siab siab, cov phiaj xwm loj loj, kev sib tw loj thiab cov chaw thauj khoom hnyav, cov tshuab loj engineering, nkoj mus rau hiav txwv thiab cov chaw ua haujlwm hauv hiav txwv.
