ASTM A516 / ASME SA516 hlau

ASTM A516 / ASME SA516
SA516 yog qib carbon steel phaj siv feem ntau hauv welded siab hlab ntsha rau nruab nrab mus rau qhov kub thiab txias. Cov khoom no yog tsim nyob rau hauv qib 55, 60, 65 thiab 70. Cov khoom no kuj muaj nyob rau hauv lub normalized mob qhov twg yuav tsum tau txhim kho notch toughness.
