A537 CL 3(Class 3) yog hais txog ib hom cua sov-kho, carbon-manganese-silicon steel phaj, txhais los ntawm ASTM A537/A537M, siv los ua fusion-welded siab hlab ntsha thiab cov qauv, muab lub zog siab dua li Chav Kawm 1 lossis 2, nrog rau qhov tsawg kawg nkaus 5 0 yields (5 MP) phaj ua tiav los ntawm quenching thiab tempering. Nws yog cov khoom siv zoo tsim nyog rau kev thov hauv cov roj, roj, thiab tshuaj lom neeg kev lag luam.

1.Qhov sib npaug ntawm ASTM A537 cl3 yog dab tsi?
Qhov sib npaug ntawm ASTM A537 Chav Kawm 3 (ib qho quenched thiab tempered steel rau cov hlab ntsha siab) suav nrog ASME SA537 Chav Kawm 3, European EN 10028-3 P420NH, German DIN 17102 WStE355, thiab Japanese JIS G3115 SPV450, tag nrho cov kev thov zoo sib xws. Cov qhab nia no sib pauv tau rau ntau qhov haujlwm, tab sis nco ntsoov xyuas nrog qhov project specifications.
2.Yog astm a537 chav kawm 3 zoo dua li chav kawm 1?
Yog lawm, ASTM A537 Class 3 feem ntau suav hais tias "zoo dua" lossis siab dua li Chav Kawm 1 vim nwsquenched thiab tempered (Q & T)Kev kho cua sov muab kev ua kom zoo dua qub thiab ua kom lub zog zoo dua qub, tshwj xeeb tshaj yog rau qis - qhov kev pabcuam kub hauv cov hlab ntsha siab, thaum Chav Kawm 1 tsuas yog ua kom zoo dua qub, muab lub zog qis dua tab sis zoo ib yam rau cov ntawv thov tsawg dua. Chav Kawm 3 muaj cov txiaj ntsig siab dua thiab lub zog tensile, ntsuas lub zog siab nrog kev txhim kho toughness uas Chav Kawm 1 tsis muaj, ua rau nws tsim nyog rau kev pabcuam hnyav dua.
3.Dab tsi yog qhov tshiab tshaj plaws ntawm ASTM A537?
Tshaj Tawm Kawg: ASTM A537/A537M – 20 (Pib Pom Zoo 2020) Siv Tau: Lub Kaum Ib Hlis 1, 2020. Hloov: A537/A537M – 13. Tsis muaj kev hloov kho thaum lub Kaum Ib Hlis 16, 2025.
