Stainless Hlau Qib 430 - Sib Nqus Stainless Hlau 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 (≤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.

Sib nqus cwj pwm

Tsis zoo li austenitic stainless hlau, qib 430 yogSib nqus, ua kom muaj txiaj ntsig zoo rau cov ntawv thov uas yuav tsum tau siv hlau nplaum.

Thaum tshav kub kub Resistance

430 stainless hlau tuaj yeem tiv taus qhov kub thiab txias mus txog 870 ° C (1600 ° F) thiab siv tas mus li txog 815 ° C (1500 ° F). Nws kuj tiv taus scaling thiab tswj cov txheej txheem kev ncaj ncees raws li cov xwm txheej no.

Qhov zoo ntawm 430 Stainless Hlau

Tus nqi -Cov: Tus nqi qis dua vim tsis muaj nickel.

Zoo Formability: Yooj yim tsim, khoov, thiab zoo li tus.

Sib nqus: Haum rau kev siv hlau nplaum.

Oxidation Resistance: Ua tau zoo ntawm qhov kub siab.

Npaj Muaj: Dav tsim thiab siv tau thoob plaws kev lag luam.

Kev txwv ntawm 430 Stainless Hlau

Tsawg Corrosion Resistance: Tsis haum rau ib puag ncig hnyav lossis siv sab nraum zoov ntev hauv huab cua hnyav.

Brittleness ntawm Tsawg Kub: Muaj peev xwm ua tau tsawg dua hauv cov ntawv thov cryogenic.

Txo Weldability: Ntau nyuaj rau weld piv rau austenitic stainless hlau, thiab cov chaw welded tej zaum yuav poob ib co corrosion kuj.

Cov ntawv thov siv

Vim nws qhov sib npaug ntawm kev ua tau zoo thiab tus nqi, 430 stainless hlau yog siv thoob plaws ntau yam kev lag luam thiab cov neeg siv khoom, suav nrog:

Khoom siv: Cov tub yees panels, lub tshuab ntxuav tais diav sab hauv, qhov cub hauv ob sab phlu.

Automotive: Trim, tso pa system Cheebtsam, thiab hniav nta.

Kev tsim vaj tsev: vov tsev, phab ntsa cladding, thiab sab hauv tsim cov ntsiab lus.

Chav ua noj: Cov tais diav, dab dej, thiab khoom siv npaj zaub mov.

Kev Siv Hluav Taws Xob: Thaum tshav kub kub exchangers, qhov cub qhov cub, thiab lwm yam kev siv uas kub tsis kam yog qhov tseem ceeb.
