Qib 440A Stainless Hlau

Kev piav qhia

Qib 440A yog martensitic stainless hlau, cov pa roj carbon tsawg tshaj plaws ntawm 440 series (440A, 440B, 440C), muab kev sib xyaw ua ke ntawm hardness, hnav tsis kam, thiab corrosion kuj. Nws muaj 16.0-18.0% chromium, uas muab kev tiv thaiv zoo corrosion nyob rau hauv ib puag ncig me me, thiab cov ntsiab lus carbon ntawm 0.60-0.75%- qis dua 440B thiab 440C- ua rau nws me ntsis formable thiab weldable dua nws cov siab dua-carbon counterpart. Raws li qib martensitic, 440A yog sib nqus thiab tuaj yeem kho cua sov (quenched thiab tempered) kom ua tiav cov hardness me ntsis thiab lub zog, ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum tau hnav tsis kam, tab sis qhov hnyav hnyav tsis tsim nyog.

Chemical Composition (wt%)

Mechanical Properties

Tensile Strength Ntau dua los yog sib npaug rau 760 MPa, Yield Strength Ntau dua lossis sib npaug ntawm 550 MPa, Elongation Ntau dua lossis sib npaug li 10%, Hardness Tsawg dua lossis sib npaug rau 269 HB (annealed); Tensile Strength Ntau dua los yog sib npaug rau 1100 MPa, Yield Strength Ntau dua los yog sib npaug rau 860 MPa, Elongation Ntau dua los yog sib npaug rau 8%, Hardness 54-58 HRC (kub-kho)

Qhov zoo

Balanced hardness thiab hnav tsis kam; zoo formability thiab weldability tshaj 440B / 440C; zoo corrosion kuj nyob rau hauv ib puag ncig me me; Sib nqus; tshav kub- kho tau rau kev ua tau zoo dua; tus nqi- zoo; yooj yim rau tshuab ntau dua -carbon 440 variants.

Daim ntawv thov

Riam, hniav, cutlery, li qub, twj tso kua mis, lub zog, bearings, cov cuab yeej phais, thiab cov khoom siv dav dav uas xav tau kev hnav tsis zoo thiab kev tiv thaiv corrosion me me.
