Kev sib piv ntawm 410 (Martensitic) thiab 430 (Ferritic) Stainless Steel: Basic Martensitic vs Basic Ferritic Qib

410 (martensitic) thiab 430 (ferritic) yog cov hlau tsis zoo tshaj plaws ntawm ob lub koom haum sib txawv, nrog rau qhov sib txawv ntawm kev ua tau zoo vim muaj cov qauv sib txawv . 410 tsom rau lub zog thiab weldability, thaum 430 tsom rau formability thiab nqi{4}}effectiveness. Qhov kev sib piv no yuav pab qhia meej txog kev xaiv ntawm cov martensitic thiab ferritic stainless hlau.

Qhov tseem ceeb ntawm kev ua tau zoo sib txawv: 1. Strength adjustability: 410 yog martensitic, tuaj yeem muaj zog los ntawm quenching thiab tempering (hardness txog 45HRC); 430 yog ferritic, tsis tuaj yeem muaj zog los ntawm kev kho cua sov, tsuas yog lub xeev annealed. 2. Corrosion resistance: 430's siab dua chromium cov ntsiab lus (16{18}}18%) ua rau nws atmospheric corrosion kuj zoo dua 410 (11.5{20}}13.5%); 410 yog qhov yooj yim rau xeb hauv qhov chaw ntub dej. 3. Formability: 430 muaj qhov txias txias zoo dua (elongation Ntau dua lossis sib npaug li 22%), haum rau stamping thiab dabtsi yog khoov; 410's formability yog me ntsis phem dua. 4. Weldability: 410 muaj weldability zoo dua, preheating tsis tas rau nyias daim hlau; 430 yog qhov ua rau muaj kev cuam tshuam ntawm intergranular tom qab vuam . 5. Kev kub siab ua haujlwm: 430's siab dua chromium cov ntsiab lus txhim kho qhov kub thiab txias oxidation tsis kam, kev pabcuam kub 200℃siab dua 410.

Siv tau Scenario Distinction: 410 yog haum rau cov khoom uas yuav tsum tau adjustable lub zog, weldability thiab nruab nrab toughness, xws li tsawg- siab li qub, twj tso kua mis, hydraulic Cheebtsam, khoom noj khoom haus tshuab brackets, thiab phais cov cuab yeej accessories. 430 yog haum rau cov khoom uas yuav tsum tau zoo formability, tsis tshua muaj nqi thiab nruab nrab corrosion kuj, xws li architectural cov khoom, cov khoom siv kho kom zoo nkauj hauv tsev, thiab cov khoom siv kho kom zoo nkauj. tsheb trim qhov chaw.

Tswv yim Q&A

Q1: Vim li cas 430 pheej yig dua 410? A1: Ob leeg yog npib tsib xee-dawb, tab sis 430's smelting txheej txheem yog yooj yim dua, thiab cov kev cai rau carbon thiab chromium cov ntsiab lus tswj yog qis dua; 430 lub lag luam tso zis ntau dua, nrog kev lag luam ntawm nplai; 430 yog li 5-10% pheej yig dua 410.

Q2: 410 puas tuaj yeem hloov 430 rau cov khoom siv stamping? A2: Tsis pom zoo . 410's formability yog phem tshaj 430, yooj yim tawg thaum stamping; 430's siab dua elongation ua rau nws tsim nyog rau txoj kev stamping duab.

Q3: Dab tsi yog qhov sib txawv corrosion ntawm 410 thiab 430 nyob rau sab nraum zoov? A3: 430's sab nraum zoov kev pabcuam lub neej yog 3-5 xyoos (xeb me ntsis), 410's yog 1-2 xyoos (pom tseeb xeb); rau cov khoom siv sab nraum zoov, 430 yog qhov xav tau yog tias tsim nyog, 410 tsuas yog tsim rau qhov chaw sab hauv tsev lossis sab nraum zoov qhuav.

Q4: 410 puas tuaj yeem siv rau siab -cov khoom kub? A4: Nws tuaj yeem siv tsawg dua lossis sib npaug li 400 degree; ntawm qhov kub siab tshaj 400 degree, nws oxidation kuj txo qis; rau siab - qhov kub ntawm qhov siab tshaj 400 degree, 430 lossis 439 raug pom zoo.

Q5: Yuav ua li cas xaiv ntawm 410 thiab 430? A5: Xaiv 410 yog tias yuav tsum tau muaj zog adjustability, weldability thiab toughness; xaiv 430 yog tias tsim tau, tus nqi qis thiab nruab nrab corrosion kuj (qhuav ib puag ncig) yuav tsum tau.
