ASTM A537 cl3 Alloy Pressure Vessel steel phaj

A537CL3 yog tempered thiab quenched silicon carbon manganese steel daim hlau uas yog npaj rau ntau lub hom phiaj. Cov kev xav tau yog piav qhia txog kev sim nrog rau txoj kev tiv thaiv thiab cov txheej txheem. Nws kuj muaj xws li variations nyob rau hauv qhov ntev, kho tej yam tsis xws luag, kom muaj nuj nqis, loj, loading, marking, ntim lwm yam. Kev lag luam yog lav hauv kev ua tiav txhua qhov kev xav tau ntawm tus neeg yuav khoom. Yog li lawv tau tsim cov phiaj los ntawm kev siv cov khoom zoo tshaj plaws ntawm cov hlau txuas ntxiv rau cov thev naus laus zis tshiab thiab cov cuab yeej niaj hnub. Tsis tas li ntawd, lawv tab tom txiav txim siab kev lag luam teeb tsa cov txheej txheem tsim khoom thiab ntau yam khoom siv raw khoom zoo rau kev tsim cov khoom.

Cov ntaub ntawv siv

ASTM Cov Qauv:
