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:

A20/A20M: Specification rau General Requirements for Pressure Vessel Plates
A435 / A435: Rau Ncaj-Beam Ultrasonic Examination ntawm Hlau Phaj
A577 / A577M: Rau Ultrasonic Angle-Beam Examination ntawm Steel Phaj
A578 / A578M: ​​Rau Ncaj-Beam Ultrasonic Examination ntawm Rolled Steel Phaj rau Kev Siv Tshwj Xeeb

Manufacturing Notes:

Hlau Phaj raws li ASTM A537 Chav Kawm 1, 2 thiab 3 yuav tsum raug tua cov hlau thiab ua raws li qhov zoo ntawm austenitic grain loj yuav tsum tau ntawm Specification A20 / A20M.

Txoj kev kho cua sov:

Txhua daim hlau raws li ASTM A537 yuav tsum tau kho cua sov raws li hauv qab no:
ASTM A537 Class 1 daim hlau yuav tsum normalized.
Chav Kawm 2 thiab Chav Kawm 3 yuav tsum tau quenched thiab tempered. Tempering kub rau Class 2 daim hlau yuav tsum tsis pub tsawg tshaj 1100 ° F [595 ° C] thiab tsis tsawg tshaj 1150 ° F [620 ° C] rau Class 3 daim hlau.
