ASTMA213 / A213M Seamless Steel Yeeb Nkab ASTMA213 / A213M Alloy Steel Yeeb Nkab "Specification rau Ferritic thiab Austenitic Alloy Steel Seamless Steel Pipes rau Boilers, Superheaters thiab Heat Exchangers"
Cov qib khoom: T2, T5, T5b, T5C, T9, T11, TI2, T21, T22, T23, T91 (Type1. Type2), T92, thiab lwm yam khoom specifications: sab nraud txoj kab uas hla 21.3mm ~ 762mm, phab ntsa thickness 2.{{ 18}mm ~ 130 hli
Cov txheej txheem ntau lawm: kub dov, kos duab txias, tshav kub nthuav dav, xa khoom raws li txoj cai: kev kho cua sov hauv lub xeev, cov khoom yuav tsum tau lees paub kom ua raws li cov kev cai ntawm TSGD7002-2006 "Hom Test Rules for Pressure Pipe Components".
ASTM A213 steel kav kuj tsim nyog rau cov kav dej kub, cov khoom siv hluav taws xob, superheaters, reheaters, petrochemical kev lag luam kav, thiab lwm yam ntawm high-pressure boilers (feem ntau siab tshaj 9.8MPa, ua hauj lwm kub ntawm 450 degree thiab 650 degree).
Lub hardness ntawm ASTM A213 yog dab tsi?
ASTM A213 Gr T2 Tube nthuav tawm qhov tsawg kawg nkaus tensile lub zog ntawm 415MPa thiab qhov tsawg kawg nkaus tawm lub zog ntawm 205MPa, uas zoo ib yam li cov txiaj ntsig ntawm qib 304 thiab 316 stainless hlau. Txawm li cas los xij, cov pa roj carbon steel no muaj qhov nyuaj dua thiab tawv, nrog qhov siab tshaj plaws Brinell hardness ntawm 163HB.
