A302 Qib A Siab Vessel Steel phaj

ASTM A302 tus qauv qhia tshwj xeeb rau cov phaj siab hauv cov hlau hlau, manganese molybdenum thiab manganese-molybdenum-nickel.
A302 Qib A steel phaj yuav tsum tau muab nkag rau hauv cov xwm txheej zoo li dov. Cov phaj yuav raug txiav kom normalized los yog kev ntxhov siab, los yog ob qho tib si. Yog A 302 Qib A saum toj no 50mm hauv thickness yuav tsum normalized.
