Lub ntsiab:
ASTM A182yog rauStainless hlauCheebtsam, whereasASTM A105(suav nrog tusHfkev ceeb toom) yog hais txogCov Hlau HlauCheebtsam.
ASTM A182yog siv rau kev siv ntsuas kub siab thiab cov khoom siv hauv siab, thiab cov khoom siv feem ntau tiv taus corrosion vim yog cov hlau stainless.
ASTM A105yog siv rauCov Hlau HlauCheebtsam hauvflangesthiabtus mivnrog kev ntsuas siab thiab ntsuas kub. TusHfqhia tias cov khoom siv no yuav dhau musHYFOSTATICATICIC, tus txheej txheem uas txhim kho qhov tseeb ntawm qhov tseeb thiab cov khoom siv neeg siv neeg.
Hauv ntej, ASTM A182 thiab ASTM A1052 thiab ASTM A105 tau haum rau cov ntawv thov sib txawv raws li lawv cov ntaub ntawv muaj pes tsawg leeg thiab siv cov tshuab raj. TusHfKev tsim qauv ntawm ASTM ASTM A105 qhia tias tus txheej txheem forging tshwj xeeb tab sis tsis hloov pauv cov khoom siv hauv qab kev faib tawm.
