ASTM A333 Cov khoom lag luam/ A333M - 16 Standard Specification rau Seamless thiab Welded Steel Yeeb Nkab rau Cov Kev Pabcuam Kub Kub thiab Lwm Cov Kev Pabcuam uas yuav tsum tau ua kom tsis muaj zog.

ASTM A333 npog phab ntsa seamless thiab welded carbon thiab alloy steel yeeb nkab npaj rau kev siv ntawm qhov kub thiab txias. Cov yeeb nkab yuav tsum tau ua los ntawm cov txheej txheem seamless lossis vuam nrog qhov sib ntxiv ntawm cov hlau tsis muaj hlau hauv kev ua haujlwm vuam. Tag nrho cov seamless thiab welded kav yuav tsum tau kho los tswj lawv cov microstructure.
