ASTM A213 Kev Qhia Tshwj Xeeb rau Cov Yeeb Nkab Steel Hlau

Oct 27, 2025

Dab tsi yog ASTM A213 kev tshwj xeeb?​

ASTM A213 yog ib tus qauv thoob ntiaj teb los ntawm Astm International uas npog Seamless Ferritic thiab Austenitic Alloy Steel Kav Rau Boiling, superheaters, thiab cua sov. Nws suav nrog ntau qib xws li T5, TPP3 thiab lwm tus, nthuav qhia meej tshwj xeeb rau lawv cov khoom lag luam thiab kuaj.
Tus qauv qhia meej qhov loj me ntawm 1/8 nti (3.2 hli) rau 5 nti (0.4 hli), txawm hais tias nws tseem tso cai rau cov kev cai.
