UNS S44003 Martensitic Stainless Hlau - Txhim Kho Hnav -Resistant Alloy

Kev piav qhia

UNS S44003 yog qhov nruab nrab-carbon variant hauv S44000 series (AISI 440B), nyob nruab nrab ntawm S44002 thiab S44004 hais txog cov ntsiab lus carbon (0.75-0.95%) thiab kev ua haujlwm. Nws khaws cov 16.0-18.0% chromium cov ntsiab lus ntawm koob, ntxiv rau 0.75-1.25% molybdenum los txhim kho hnav tsis kam thiab pitting tiv thaiv piv rau S44002. Nws cov qauv martensitic ua kom cov khoom sib nqus, thiab nws tuaj yeem ua kom sov-kho kom ua tiav hardness siab dua S44002, thaum tseem tshuav ntau tshaj li S44004. Tsis zoo li S44002, S44003 muaj kev nce qib hauv kev hnav tsis kam, ua rau nws tsim nyog rau cov ntawv thov uas qhov ua haujlwm ntev yog qhov tseem ceeb tab sis kev ua haujlwm tseem xav tau. Nws ua tau zoo nyob rau hauv qhuav los yog me ntsis corrosive tej yam kev mob, ua rau nws zoo tagnrho rau high-kev ua tau zoo ntawm industrial Cheebtsam.

Chemical Composition (wt%)

C: 0.75-0.95, Cr: 16.00-18.00, Mn Tsawg dua lossis sib npaug 1.00, Si Less dua lossis sib npaug 1.00, P Tsawg dua lossis sib npaug 0.045, S Tsawg dua lossis sib npaug 0.030, Mo: 0.75-1.75 lossis sib npaug Ni

Mechanical Properties

Tensile Strength Ntau dua los yog sib npaug rau 860 MPa, Yield Strength Ntau dua lossis sib npaug rau 620 MPa, Elongation Ntau dua lossis sib npaug li 8%, Hardness Tsawg dua lossis sib npaug rau 285 HB (annealed); Tensile Strength Ntau dua los yog sib npaug rau 1250 MPa, Tawm Zog Ntau dua lossis sib npaug rau 960 MPa, Elongation Ntau dua lossis sib npaug li 6%, Hardness 56-60 HRC (kub-kho)

Qhov zoo

Siab hnav tsis kam tshaj S44002; molybdenum- txhim kho pitting tsis kam; cua sov- kho tau kom siab hardness; Sib nqus; balanced processability (formability / weldability) ntawm S44002 thiab S44004; zoo corrosion kuj nyob rau hauv ib puag ncig me me.

Daim ntawv thov

High- cov hniav ua tau zoo, riam, bearings, li qub, lub zog, twj tso kua mis, thiab cov khoom lag luam uas xav tau kev hnav zoo dua piv rau S44002.

Qib sib npaug

AISI 440B, EN 1.4125, GB 8Cr17, SUS440B
