General Product Description
ASTM A537 specification yog tus qauv Specification rau Siab Vessel Phaj, Thaum tshav kub kub-Kho, Carbon-Manganese-Silicon Steel siv nyob rau hauv daim ntawv thov ntawm fusion welded siab hlab ntsha thiab cov qauv. Cov ntawv thov ib txwm yog cov hlab ntsha siab uas tsim los rau nruab nrab thiab qis dua - qhov kev pabcuam kub uas yuav tsum tau ua kom muaj kev sib tw zoo heev nrog rau API 650 thiab API 620 cia tso tsheb hlau luam.

Charpy V-Qhov kev xav tau ntawm kev cuam tshuam Toughness yuav raug txiav txim raws li qhov yuav tsum tau ua ntxiv (S5). Qhov tsawg kawg nkaus Charpy V-qhov cuam tshuam rau lub zog muaj nuj nqis ntawm 30 ft-lbs [41 J] ntawm - 40℃F [-40 degree] nyob rau hauv cov qauv longitudinal yog ib qho kev cuam tshuam ntxiv rau qhov yuav tsum tau muaj zog.
Tshuaj muaj pes tsawg leeg
Ua tau raws li cov cai ntawm ASTM A537 Class 1 / SA537 Class 1, raws li qhia hauv qab no. ASTM A20 txwv siv rau cov khoom tsis tau teev tseg.

Tolerances
Thickness, dav, thiab ntev kam rau ua rau A537 Chav Kawm 1 / SA537 Chav Kawm 1 raws li ASTM A20 cov cai. Kev ua siab ntev rau kev ua raws li - khoom siv yog ½ ASTM A20. Thicknesses<0.375" (0.250"-0.374") will only be supplied to full standard ASTM A20 flatness tolerance.
Kev Xa Khoom
ASTM A537 Chav Kawm 1 / SA537 Chav Kawm 1 yog nkag rau hauv cov xwm txheej zoo li qub.
