Ib qho alloy muaj npe nrov rau nws lub zog zoo dua, tiv thaiv corrosion, thiab zoo nkauj, stainless hlau tau hloov pauv ntau yam lag luam. Txawm li cas los xij, kev taw qhia ntau yam ntawm cov qib stainless hlau tuaj yeem ua haujlwm txaus ntshai. Tsis txhob ntshai, raws li cov lus qhia dav dav no nkag mus rau hauv lub ntiaj teb tsis sib xws ntawm stainless hlau, muab koj cov kev paub los xaiv cov qib zoo meej rau koj cov kev xav tau tshwj xeeb.
Taw qhia rauStainless hlau: Cov khoom siv ntev ntev, ntau yam
Stainless hlau yog lub kaus mom uas npog ntau yam ntawm cov alloys paub txog lawv qhov tshwj xeeb muaj peev xwm tiv thaiv corrosion, cov cuab yeej ntaus nqi tsawg kawg yog 10.5% chromium. Cov txheej tiv thaiv no, lub npe hu ua zaj duab xis passive, tsim tshwm sim thaum raug oxygen, tiv thaiv cov hlau hauv qab los ntawm kev puas tsuaj ntawm ib puag ncig.
To taub covStainless hlau Qib System: Decoding tus lej
Lub koom haum American Iron thiab Steel (AISI) tau tsim cov txheej txheem lej los txheeb xyuas cov qib stainless hlau. Txhua qib raug txheeb xyuas los ntawm tus lej peb tus lej, nrog thawj tus lej qhia cov koob (austenitic, ferritic, martensitic, duplex, lossis nag lossis daus hardenable), tus lej thib ob qhia txog cov ntsiab lus nickel, thiab tus lej thib peb qhia cov ntsiab lus ntxiv lossis kev hloov kho.
Sab hauv Lub Ntiaj Teb Ntawm Cov Hlau Stainless: Uncovering tsib Major Series
Austenitic Stainless Steels: Txhua-Rounders
Austenitic stainless hlau, sawv cev los ntawm 300 series, yog cov khoom siv ntau yam thiab siv dav. Cov yam ntxwv los ntawm cov ntsiab lus nickel siab, lawv muaj cov qauv zoo heev, weldability, thiab corrosion kuj, ua rau lawv zoo tagnrho rau kev ua zaub mov, tshuaj, thiab kev siv kho mob. Feem ntau siv qib suav nrog 304 (lub hom phiaj dav dav), 316 ( qib marine), thiab 310 (siab kub).
Ferritic Stainless Steels: Cov Hlau Champions
Ferritic stainless hlau, sawv cev los ntawm 400 series, paub txog lawv cov khoom sib nqus, lub zog siab, thiab kev ua haujlwm zoo. Txawm li cas los xij, lawv muaj cov ntsiab lus nickel qis dua austenitic stainless hlau, ua rau lawv tsis tshua muaj corrosion. Cov ntawv thov feem ntau suav nrog cov khoom siv tsheb, cov khoom siv, thiab cov khoom siv hauv tsev. Cov qib tseem ceeb suav nrog 430 (martensitic transformation), 409 (automotive interior), thiab 446 (architectural).
Martensitic Stainless Steels: Cov Kws Tshaj Lij Hloov Hloov
Martensitic stainless hlau, sawv cev los ntawm 400 series, muaj zog thiab hardness vim lawv martensitic microstructure. Txawm li cas los xij, lawv tsis tshua muaj ductile thiab muaj kev cuam tshuam rau corrosion dua li austenitic stainless hlau. Cov ntawv thov suav nrog cutlery, cov cuab yeej phais, thiab cov khoom hnav. Cov qib siv feem ntau yog 410 (muab tais diav), 420 (zoo nkauj), thiab 440 (siab hardness).
Duplex Stainless Hlau: Ib qho kev sib xyaw muaj zog
Duplex stainless hlau yog ib qho kev sib haum xeeb ntawm cov qauv austenitic thiab ferritic uas muaj kev sib xyaw tshwj xeeb ntawm lub zog siab, corrosion resistance, thiab weldability. Nws cov ntsiab lus chromium siab dua txhim kho nws txoj kev tiv thaiv chloride kev ntxhov siab tawg, ua rau nws tsim nyog rau kev siv dej hiav txwv thiab ntug dej hiav txwv. Cov qib tseem ceeb suav nrog 2205 (Oil & Gas), 2304 (Super Duplex), thiab 2507 (Super Duplex).
Precipitation Hardening Stainless Steel: Age Hardening Warrior
nag lossis daus hardening stainless hlau, sawv cev los ntawm qib 17-4PH thiab X70, ua tiav lawv lub zog thiab tawv tawv los ntawm kev kho cua sov hu ua nag lossis daus hardening. Lawv zoo heev corrosion kuj thiab seem stability ua rau lawv zoo tagnrho rau aerospace, valve Cheebtsam, thiab high-pressure daim ntaub ntawv.
Nkag mus rau lub ntiaj teb ntawm stainless hlau nrog kev ntseeg siab
Nrog rau cov lus qhia dav dav no raws li koj lub compass, tam sim no koj tuaj yeem taug kev mus rau ntau lub ntiaj teb ntawm qib stainless hlau. Los ntawm kev ua tib zoo xav txog cov yam ntxwv, kev siv, thiab kev txwv ntawm txhua hom, koj tuaj yeem txiav txim siab kom paub tseeb tias ua tau raws li koj cov kev xav tau tshwj xeeb thiab ua kom muaj kev ua tau zoo ntev ntev los ntawm koj cov khoom tsim stainless hlau.
