201 Stainless Steel (UNS S20100): Cov Manganese -Txhim Kho Tus Nqi- Ua Tau Zoo Austenitic

Hom 201 yog tus ua haujlwm ntawm chromium-manganese-nickel austenitic tsev neeg. Los ntawm kev hloov ib feem loj ntawm cov npib tsib xee ntawm 304 nrog manganese thiab nitrogen, nws xa cov qauv austenitic ntawm tus nqi qis dua. Kev lag luam tawm - tawm yog kev tiv thaiv corrosion, thiab kev ua haujlwm engineering yog kom phim cov qib rau cov ntawv thov uas qhov kev lag luam tawm - tawm yog txais.

Tshuaj muaj pes tsawg leeg rau ASTM A240

Element	201 (UNS S20100)
Carbon (C), max	0.15%
Manganese (Mn)	5.50-7.50%
Phosphorus (P), max	0.060%
Sulfur (S), max	0.030%
Silicon (Si), max	1.00%
Chromium (Cr)	16.00-18.00%
Nickel (Ni)	3.50-5.50%
Nitrogen (N), max	0.25%

Nitrogen yog lub hom phiaj austenite stabilizer thiab ntxiv dag zog rau lub annealed matrix. Cov ntsiab lus ntawm cov manganese siab yog lub ntsiab lus ntawm qib thiab yog vim li cas nws cov khoom sib tsoo, kev siv tshuab ua haujlwm thiab kev ua haujlwm- cov lus teb nyuaj txawv ntawm 304.

Mechanical Properties thiab Downgauging Case

Khoom (yam tsawg kawg nkaus, ASTM A240)	201	304
Tensile zog	655 MPa ua	515 MPa ua
0.2% pov thawj muaj zog	310 MPa	205 MPa
Elongation	40%	40%

Lub zog muaj zog ntau dua ntawm 201 nyob rau hauv cov xwm txheej annealed txhais tau hais tias ib ntus 201 tuaj yeem nqa tib lub nra hnyav li 304 seem hauv lub zog- txwv kev tsim, uas yog lub hauv paus ntawm nws cov nqi kom zoo dua hauv daim ntawv thov. Qhov kev sib piv siv tau tsuas yog thaum muaj kev tiv thaiv corrosion thiab cov qauv tsim tau txaus siab.

Corrosion Resistance piv nrog 304

201 yog tsim nyog nyob rau hauv qhuav nyob rau hauv tsev cua, dej tshiab thiab me me nyob deb nroog kev pab cuam. Nws qis nickel thiab ntau dua manganese cov ntsiab lus ua rau nws raug ntau dua 304 rau pitting thiab crevice corrosion los ntawm chlorides, nrog rau txoj kev ntsev thiab dej hiav txwv, thiab mus tua los ntawm tej acids. Nws feem ntau tsis pom zoo rau cov ntug hiav txwv dej, tshuaj lom neeg lossis khoom noj khoom haus -xov mus rau qhov chaw nyob ntev - yuav raug rau cov dej noo thiab chlorides.

Tsim, Vuam thiab Finishing

201 daim ntawv thiab kos tau zoo, tab sis nws ua hauj lwm - hardens sai dua 304, yog li deformation loj yuav tsum tau intermediate annealing. Cov txheej txheem austenitic vuam siv tau; vim hais tias cov ntsiab lus manganese nce kub - tawg rhiab heev, 308L muab tub lim feem ntau pom zoo kom tau txais txiaj ntsig zoo tshaj plaws. Cov qib siv lub ci ci, ntxim nyiam polish, uas txhawb nqa nws cov kev siv zoo nkauj, thiab cov neeg tsim khoom yuav tsum xav kom muaj cov qauv sib txawv thaum sib tsoo thiab tshuab.

Tej kev siv

Tsev noj mov hollowware xws li lauj kaub thiab tais, dab dej dab dej, tsawg-nqi cookware, zoo nkauj rooj tog tubing, nra racks, khoom trim, sab hauv tes, elevator décor thiab qab nthab panels nyob rau hauv ib puag ncig tswj.

FAQ

Q1: Dab tsi yog 201 stainless hlau?

A: Ib chromium-manganese-nickel austenitic qib (UNS S20100) nrog 16-18% chromium, 3.5-5.5% nickel thiab 5.5-7.5% manganese, tsim los txo tus nqi npib tsib xee.

Q2: Puas yog 201 corrosion resistant li 304?

A: Tsis yog . 201 yog qhov cuam tshuam rau cov tshuaj chloride pitting thiab crevice corrosion thiab rau qee cov kua qaub; nws suits qhuav sab hauv tsev thiab ib puag ncig me me.

Q3: Vim li cas 201 muaj zog dua 304 nyob rau hauv cov mob annealed?

A: Kev sib xyaw ntawm manganese thiab nitrogen ntxiv dag zog rau cov austenite, tsa lub zog annealed tawm los saum toj ntawm 304.

Q4: 201 puas tuaj yeem welded?

A: Yog, nrog rau cov txheej txheem austenitic; 308L muab tub lim feem ntau pom zoo kom txo qhov kub - kev pheej hmoo tawg los ntawm cov ntsiab lus manganese.

Q5: Qhov twg yog 201 feem ntau siv?

A: Hollowware, dab dej, cookware, zoo nkauj tubing thiab trim, nra racks thiab sab hauv architectural panels uas tus nqi txiav txim siab thiab kev pab cuam yog me me.

Q6: Puas tuaj yeem 201 hloov 304?

A: Tsuas yog qhov twg corrosion loads tsawg thiab tus tsim siv tau lub zog yield ntau dua; nyob qhov twg cov dej noo, ntsev lossis tshuaj lom neeg, 304 yog qhov kev xaiv zoo dua.
