A302 Qib B steel phaj tus qauv tshwj xeeb rau cov phaj siab siab hauv cov hlau hlau, manganese molybdenum thiab manganese-molybdenum-nickel.
A302 Qib B steel phaj yuav tsum tau muab nkag rau hauv raws li - dov mob. Cov phaj yuav raug txiav kom normalized los yog kev ntxhov siab, los yog ob qho tib si. Yog A 302 Qib B siab tshaj 50mm hauv thickness yuav tsum normalized.
