P235TR1 yog cov yeeb nkab hlau uas nws cov tshuaj lom neeg feem ntau ua raws li tus qauv EN 10216-1.lub Hoobkas tshuaj lom neeg, cov hlab ntsha, kev tsim kho kav dej thiab rau kev sib koom ua kelub hom phiaj ntawm kev tsim kho tshuab.

Raws li tus qauv, cov tshuaj lom neeg ntawm P235TR1 suav nrog cov ntsiab lus carbon (C) txog li 0.16%, silicon (Si) txog li 0.35%, manganese (Mn) cov ntsiab lus ntawm 0.30-1.20%, phosphorus (P) thiab sulfur (S). ) cov ntsiab lus yog siab tshaj plaws 0.025% feem. Tsis tas li ntawd, raws li cov qauv yuav tsum tau ua, cov khoom sib xyaw ntawm P235TR1 kuj tseem yuav muaj cov khoom me me xws li chromium (Cr), tooj liab (Cu), nickel (Ni) thiab niobium (Nb). Kev tswj hwm cov tshuaj lom neeg no tuaj yeem ua kom ntseeg tau tias P235TR1 cov kav hlau muaj cov khoom siv kho tshuab thiab kev tiv thaiv corrosion, ua rau lawv tsim nyog rau kev siv hauv qee qhov kev siv hauv kev lag luam tshwj xeeb.

Los ntawm kev pom ntawm cov tshuaj lom neeg, P235TR1 cov ntsiab lus carbon qis pab txhim kho nws qhov weldability thiab processability, thiab nws cov ntsiab lus silicon thiab manganese pab txhim kho nws lub zog thiab corrosion tsis kam. Tsis tas li ntawd, phosphorus thiab sulfur cov ntsiab lus yuav tsum tau tswj hwm ntawm qib qis kom ntseeg tau tias cov khoom siv purity thiab processability. Qhov muaj cov ntsiab lus kab xws li chromium, tooj liab, nickel thiab niobium yuav muaj kev cuam tshuam rau qee yam khoom ntawm cov kav hlau, xws li kev tiv thaiv cua sov lossis corrosion tsis kam.

Ntxiv rau cov tshuaj lom neeg sib xyaw, cov txheej txheem tsim khoom, cov txheej txheem kho cua sov thiab lwm yam ntsuas kev ua tau zoo ntawm P235TR1 steel yeeb nkab kuj yog cov yam tseem ceeb uas cuam tshuam rau nws qhov kev ua tau zoo kawg. Feem ntau, cov tshuaj lom neeg sib xyaw ntawm P235TR1 steel yeeb nkab yog ib qho ntawm cov yam tseem ceeb kom ntseeg tau tias nws ua tau raws li cov qauv tsim nyog thiab tuaj yeem ua tau raws li cov hom phiaj tshwj xeeb.
