Dab tsi yog qhov sib txawv ntawm gb 5310 25 mng steel yeeb nkab thiab 20mng steel yeeb nkab
Ob qho tib si 25mng thiab 20mng hlau kav hlau yog seamless steel kav rau kev kub siab me ntsis hauv tshuaj lom neeg muaj pes tsawg leeg. Nov yog qhov sib txawv tseem ceeb ntawm ob:
Tshuaj lom neeg cov tshuaj:
25MNG: lub ntsiab muaj pes tsawg leeg suav nrog 0. 25% mandanese (mn), uas tseem yog lub hauv paus ntawm nws lub npe. Ib qho ntxiv, cov ntsiab lus ntau zaus feem ntau suav cov pa roj carbon (c) ncig {{}. 25%}. {}}}}}. {}}}.}}%. Qhov tshwj xeeb tshuaj lom neeg muaj pes tsawg leeg muaj cov tshuaj ntsuab qis dua (p) thiab sulfur (cov s), chromium (Nickel (NI)
2 {0 mng: lub ntsiab muaj pes tsawg leeg suav nrog 0. 20%}. {}}. 24%. Ib yam li ntawd, nws cov ntsiab lus phosphorus thiab cov Sulphur cov ntsiab lus tseem tswj tau nyob rau hauv qis dua, raws li cov kev txwv ntawm lwm cov ntsiab lus uas seem.
Siv thiab Qauv:
Ob lub kav dej steel ua raws cov GB 5310-2017 tus qauv thiab feem ntau yog siv rau hauv siab lub rwj. Lawv muaj cov txheej txheem siab thiab zoo qauv kev ruaj khov los hloov kho kom haum rau qhov kub thiab qhov chaw siab siab. Koj tuaj yeem xaiv ib qho khoom siv steel yeeb nkab tsim koj cov phiaj xwm, lossis koj tuaj yeem tiv tauj peb kom pom zoo cov khoom tsim qauv steel yeeb rau koj.
