A537 CL1 Normalized Pressured Vessel Steel Phaj

ASTM A537 tus qauv yog hais txog lub siab lub nkoj daim hlau, cov khoom siv hauv cov cua sov kho, carbon-manganese silicon steel. Raws li qhov sib txawv ntawm lub zog thiab kev kho cua sov, nws nyob ntawm chav kawm 1, 2 thiab 3.
Qhov siab tshaj plaws thickness raws li ASTM A537 Chav Kawm 1 yog 100 hli [4 nti], thiab 150 hli [6 nti] rau Chav Kawm 2 thiab Chav Kawm 3.
Cov khoom siv yog cov hlau tsis zoo uas tau kho cov cua sov thiab ua rau muaj qhov tshwm sim ntau dua thiab lub zog tensile ntau dua li cov qauv ASTM A516 ntau dua. Cov hlau yog zoo tagnrho rau siv nyob rau hauv cov kev pab cuam pressurized ob leeg nyob rau hauv boilers thiab siab hlab ntsha

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.
