Lub zog tawm los ntawm ASTM A 213 304 yog dab tsi?
Lub zog tawm los ntawm ASTM A 213 304 yog dab tsi?
Qhov tsawg kawg nkaus lub zog rau ASTM A213 TP304 qib stainless hlau yog 205 MPa (30 ksi), uas yog tus qauv tus nqi feem ntau teev nrog rau qhov tsawg kawg nkaus tensile zog ntawm 515 MPa (75 ksi) thiab qhov tsawg kawg nkaus elongation ntawm 40%. Tus nqi no sawv cev rau qhov kev ntxhov siab uas cov khoom pib mus tas li deformation thiab yog ib qho tseem ceeb ntawm kev ua tau zoo rau cov hlab ntsha thiab cov khoom siv hluav taws xob uas siv los ntawm cov qauv no.
Dab tsi yog qhov yield zog ntawm stainless hlau?
Stainless hlau paub txog nws zoo heev corrosion kuj, tab sis nws lub zog yield nws txawv nyob ntawm seb hom tshwj xeeb: Austenitic stainless hlau, xws li 304 thiab 316 stainless hlau, muaj corrosion kuj zoo tab sis nruab nrab yield zog, feem ntau nyob ib ncig ntawm 200-300 megapascals (30,000-45,000 phaus ib square nti).

Cov yam ntxwv tseem ceeb ntawm ASTM A213 TP304:
Yield zog (0.2% offset):Yam tsawg kawg nkaus 205 MPa (30 ksi)
Tensile zog:Yam tsawg kawg nkaus 515 MPa (75 ksi)
Elongation (2-nti lossis 50 hli ntsuas qhov ntev):Tsawg kawg 40% (qee qhov chaw qhia 35%)
Lus Cim Tseem Ceeb:
Standard vs. Tus nqi zoo:Thaum 205 MPa yog qhov tsawg kawg nkaus yuav tsum tau, lub zog tawm los tiag tiag yuav txawv me ntsis nyob ntawm kev tsim khoom thiab kev kho cua sov, tab sis tus qauv lav qhov tsawg kawg nkaus tus nqi.
Variations:Rau ASTM A213 TP304L, uas muaj cov ntsiab lus ntawm cov pa roj carbon tsawg, qhov tsawg kawg nkaus lub zog yog 170 MPa (25 ksi).
ASTM A213 Cov Lus Qhia:Qhov kev qhia tshwj xeeb no suav nrog ferritic, austenitic, thiab duplex alloy steel boiler raj, superheater raj, cov raj kub exchanger, thiab cov kav hlau alloy.
