P235TR1 yog cov khoom siv steel hlau uas nws cov tshuaj muaj kuab lom feem ntau ua raws li EN 10216-1 tus qauv.Tshuaj Tsob Nroj, hlab ntsha, kev tsim kho kev siv hluav taws xob thiab rau ib qhoNeeg kho tshuab Engineering Lub Hom Phiaj.

Raws li tus qauv, cov tshuaj lom neeg muaj pes tsawg leeg ntawm P235tr1 suav nrog cov pa roj carbon (c) Cov ntsiab lus nce mus txog 0,30% Cov ntsiab lus tseem ceeb tshaj plaws 0.025% feem. Tsis tas li ntawd, raws li cov qauv kev cai, cov muaj pes tsawg leeg ntawm P235tr1 kuj tseem muaj cov nqi chromium (CU), NIOBEL (NB). Tswj cov khoom siv tshuaj no tuaj yeem ua kom pom tseeb tias P235tr1 cov kav hlau tsim nyog thiab corrosion tsis tsim nyog, ua rau lawv haum rau siv hauv qee cov ntawv thov kev lag luam tshwj xeeb.

Los ntawm cov tshuaj lom neeg sib xyaw ua ke, P235TR1 cov ntsiab lus carbon qis pab txhim kho nws cov lus cua thiab cov khoom sib xyaw ua ke thiab corrosion tsis kam. Ib qho ntxiv, phosphorus thiab cov lus faj cov ntsiab lus yuav tsum tau tswj hwm ntawm theem qis los xyuas kom meej cov khoom siv purity thiab txheej txheem. Lub xub ntiag ntawm kab kawm xws li chromium, tooj liab, xws li niobium pipes, xws li kub ua kom tsis taus lossis corrosion tsis kam.

Ntxiv rau cov tshuaj muaj pes tsawg leeg, cov txheej txheem tsim khoom, kev kho cua sov thiab lwm yam kev ua haujlwm kub thiab lwm yam kev ua tau zoo rau lub cev muaj feem cuam tshuam rau nws qhov kev ua tau zoo kawg nkaus. Feem ntau, cov tshuaj lom neeg tshuaj lom neeg ntawm P235TR1 yeeb nkab yog ib qho tseem ceeb ntawm cov qauv thiab tuaj yeem ua tau raws li lub hom phiaj engineering.
