ASTM A537 Qib 1yog ib qho normalized, cua sov-kho carbon-manganese-silicon steel phaj siv rau fusion-welded siab hlab ntsha thiab boilers, muab superior zog thiab toughness piv rau standard steels rau nruab nrab mus rau qis- kub, pressurized daim ntaub ntawv nyob rau hauv cov roj, roj, thiab petrochemical industries. Nws tau paub txog nws cov txiaj ntsig zoo zog (nyob ib puag ncig 345 MPa) thiab lub zog tensile (485-620 MPa) vim cov txheej txheem normalization, ua rau nws tsim nyog rau qhov xav tau ib puag ncig.
