Dab tsi yog qhov sib txawv tseem ceeb ntawm 201 thiab 304 stainless hlau

Kev sib piv tshuaj lom neeg: Stainless hlau 201 vs 304

Element	Stainless hlau 201	Stainless hlau 304
Chromium	16-18%	18-20%
Nickel	3.5-5.5%	8-10.5%
Manganese	5.5-7.5%	2% max
Cov pa roj carbon	0.15% max	0.08% max
Hlau	Tshuav	Tshuav

 

Qhov tseem ceeb tshem tawm ntawm lub rooj no yog qhov ntawdstainless hlau 201muaj tsawg nickel thiab manganese ntau duastainless hlau 304. Nickel yog ib qho khoom kim heev uas txhim khu kev tiv thaiv corrosion, uas yog vim li cas 304 feem ntau tiv taus ntau dua 201. Txawm li cas los xij, qhov no kuj ua rau 201 tus nqi ntau dua - kev xaiv zoo nyob rau qee kis.

 

Mechanical Properties: Lub zog ntawm Stainless Hlau 201 vs 304

Stainless hlau 201thiabstainless hlau 304txawv ntawm lawv cov khoom siv kho tshuab, ua rau lawv haum rau kev siv sib txawv. Nov yog saib yuav ua li cas lawv cov cuab yeej siv zog sib piv:

Tensile zog: Stainless hlau 201 muaj ib tug me ntsis siab tensile zog tshaj 304, uas txhais tau tias nws muaj peev xwm tiv taus ntau nro yam tsis deforming.

Yield zog: Txawm hais tias 201 tsawg dua ductile tshaj 304, nws lub zog tawm los yog siab dua, ua rau nws tsim nyog rau cov ntawv thov kom ruaj khov.

Hardness: Ob qib yog ib qho nyuaj thiab ruaj khov, tab sis 304 yog me ntsis resistant rau kev cuam tshuam thiab kev ntxhov siab vim nws cov ductility ntau dua.
