Qib 431 feem ntau khaws thiab muab tso rau hauv "Txoj Cai T", nrog rau lub zog tensile ntawm 850 - 1000MPa.
* Annealed tensile zog yog ib yam rau mob A ntawm ASTM A276; annealed hardness yog qhov siab tshaj plaws. Qib 431 tsuas yog tsis tshua muaj nyob rau hauv annealed Condition A.
# Qib 431 yuav tsum tsis txhob tempered ntawm 425 thiab 600 degree, vim muaj kev cuam tshuam tsis zoo cuam tshuam nrog qhov kub thiab txias.
