S275N yog tus qauv European (EN) qis alloy cov qauv hlau, lawv muaj cov khoom siv zoo heev thiab kev tiv thaiv corrosion, thiab tau siv dav hauv kev tsim kho, txuas hniav, tshuab, petrochemicals, marine engineering thiab lwm yam haujlwm.
Cov muaj pes tsawg leeg ntawm S275N yog tsim los ntawm carbon (C), silicon (Si), manganese (Mn) thiab lwm yam. Ntawm lawv, cov pa roj carbon yog cov pob txha caj qaum ntawm cov hlau, uas tuaj yeem ua rau lub zog thiab tawv tawv ntawm cov hlau, tab sis kuj txo cov plasticity thiab toughness ntawm cov hlau. Silicon thiab manganese tuaj yeem tsim ib qho kev daws teeb meem nrog cov pa roj carbon monoxide, ua kom lub zog thiab hardness ntawm cov hlau, thaum tuav lub plasticity thiab toughness ntawm hlau. Txhawm rau kom muaj zog thiab hardness ntawm cov hlau, me me ntawm phosphorus (P), sulfur (S) thiab lwm yam tseem ntxiv.
S275N thiab S275NL tau dav siv hauv kev tsim kho, txuas hniav, tshuab, petrochemicals, marine engineering thiab lwm yam haujlwm. Hauv cov teb no, S275N feem ntau yog siv los tsim cov hlab ntsha loj, reactors, yees thiab lwm yam khoom siv tseem ceeb. Lawv tau siv dav hauv cov teb no vim lawv qhov kev ua tau zoo tag nrho thiab cov nqi siv tau zoo, uas tuaj yeem ua kom muaj kev nyab xeeb thiab ruaj khov ntawm cov khoom siv.
