ASME SA537 Chav Kawm 1 yog cov pa roj carbon monoxide-manganese- silicon steel phaj siv feem ntau rau cov hlab ntsha thiab cov boilers, muab cov tawv tawv zoo thiab lub zog ntawm qhov nruab nrab kub. Hauv qab no, kuv muab cov ncauj lus kom ntxaws sib piv nrog nws cov ntaub ntawv tseem ceeb sib npaug raws li cov qauv thoob ntiaj teb. Qhov sib npaug suav nrog ASTM A537 Chav Kawm 1, EN 10028-2 P355GH, DIN 17155 19Mn6, JIS G3115 SPV355, thiab ASTM A671 Gr. cd70 ua.
