430 Stainless Hlau - Sib Nqus Qib

 

Kev sib xyaw thiab cov qauv

430 stainless hlau yog aferritic stainless hlau, txhais tau tias nws muaj lub cev -centered cubic (BCC) crystal qauv. Tsis zoo li cov qib austenitic xws li 304 lossis 316, nws tsis muaj npib tsib xee ua cov khoom tseem ceeb alloying. Hloov chaw, nws feem ntau yog tsim los ntawm:

Chromium (16-18%)- Muab kev tiv thaiv corrosion thiab scale kuj.

Carbon (tsawg dua lossis sib npaug rau 0.12%)- Khaws qis kom tswj tau qhov ductility thiab toughness.

Hlau (sib npaug)- Lub hauv paus hlau ntawm lub alloy.

Cov ntsiab lus me- Xws li manganese, silicon, phosphorus, thiab sulfur, uas ua rau muaj zog, machinability, thiab lwm yam ntxwv.

Qhov tsis muaj npib tsib xee yog ib qho ntawm cov laj thawj tseem ceeb vim li cas 430 stainless hlau tsis kim dua li cov qib austenitic.

Cov khoom tseem ceeb

Corrosion Resistance

430 stainless hlau muaj kev tiv thaiv zoo rau atmospheric corrosion, tshuaj me me, thiab oxidation ntawm qhov kub siab. Txawm tias tsis zoo li corrosion-resistant li 304 lossis 316, nws ua tau zoo nyob rau hauv ib puag ncig sab hauv tsev thiab nruab nrab sab nraum zoov. Txawm li cas los xij, nws tsis pom zoo rau qhov chaw corrosive heev, xws li marine lossis acidic ib puag ncig.

Mechanical Properties

Tensile zogUa haujlwm siab: ~ 450 MPa

Yield zogUa haujlwm siab: ~ 205 MPa

Elongation ntawm Break: ~22%

Hardness: ~ HWV 89

Cov txiaj ntsig no ua rau 430 stainless hlau haum rau cov ntawv thov uas xav tau lub zog nruab nrab thiab zoo formability.
