Qhov sib txawv ntawm 430 vs 304 stainless

Stainless hlau los nyob rau hauv ntau cov qib sib txawv . txhua qib muaj zog, thiab lwm yam cim muaj zog ntawm stainless hlau- 430304.

1. Dab tsi yog tus hlau stainless?

Zoo li lwm daim qauv hlau, stainless hlau yog ib qho alloy ntawm cov hlau thiab cov chromium yog li cas cov hlau tsis muaj zog, uas pab ua kom ntev li qub lub neej

Cov cuab yeej siv roj carbon ntau feem ntau tau siv rau cov cuab yeej siv hluav taws xob, cov khoom siv tshuaj thiab cov khoom siv tshuaj ntsuab} Nws zoo nkauj dua li cov roj carbon steel.

2. Cov qhab nia sib txawv ntawm cov hlau qhia li cas?

Cov hlau lag luam muaj cov hlau los ntawm cov qib kom ntseeg tau tias yog siv cov qauv steel yog tsim nyog los ntawm txhua qhov uas ua rau cov hlau uas tsis sib xws.

Txheeb xyuas cov koom haum hlau cov qauv txheej txheem li cas thoob plaws lub ntiaj teb no ..

3. Dab tsi yog 430 stainless hlau?

Ntaus 430 stainless hlau yog ib tug me, corrosion-resistant hlau uas tuaj yeem yooj yim bent, ncab, lossis kos.

Nws muaj cov tshuaj lom neeg nram qab no:

Hlau=Tshuav Nyem

Carbon <0.12%

Chromium=16-18%

Nickel <0.75%

Manganese <1.0%

Silicon <1.0%

Phosphorus <0.040%

Sulphur <0.30%

Nws kuj muaj cov ntsiab lus hnyav heev thiab tsis muaj cov nqaj ruaj khov ua rau qib no nyuaj rau weld .

Ntaus 430 stainless hlau muaj tsawg kawg vim muaj lub zog ntawm 30}}} Nws muaj nyob rau hauv 430 stainless hlau ntawv {}}

4. Dab tsi yog 304 stainless hlau?

Hom 304 stainless hlau yog qhov dav ntau siv ntawm tag nrho cov stainless hlau qib {1} Nws feem ntau tshwm sim hauv chav ua noj thiab kev siv lag luam.

Cov qib no ntawm Stainless Hlau tshwj xeeb cov tshuaj lom neeg hauv qab no:

Hlau=Tshuav Nyem

Carbon=0.0} - 0.07%

Chromium=17.50}} - 19.50%

Manganese=0.0} - 2.0%

Silicon=0.0 - 1.0%

Phosphorous=0.0} - 0.05%

Sulphur=0.0} - 0.03%

Nickel=8.0} - 10.5%

Nitrogen=0.0} - 0.11%

Hom 304 tuaj yeem muab welded tolbon steel siv tig los yog msi thiab tsawg kawg tensile lub zog ntawm 75 ksi.

Qhov no stainless hlau qib yog niaj hnub ua rau muaj ntau hom, suav nrog: 304 stainless hlau raj, 304 stainless hlau raj, thiab 304 stainless hlau raj, thiab 304 stainless hlau raj, thiab 304 stainless hlau raj, thiab 304 stainless hlau raj, thiab 304 stainless hlau tub rog {}}
