Qib SUS420J1 / J2 Stainless Hlau

Kev piav qhia

Qib SUS420J1 thiab SUS420J2 yog nruab nrab-carbon martensitic stainless hlau, tsim los rau cov ntawv thov uas yuav tsum muaj qhov sib npaug ntawm qhov tawv, hnav tsis kam, thiab nruab nrab corrosion kuj. Ob qib muaj 12.0-14.0% chromium, muab kev tiv thaiv corrosion zoo dua SUS410 thiab SUS410L, thiab yog sib nqus vim lawv cov qauv martensitic. Qhov sib txawv tseem ceeb ntawm SUS420J1 thiab SUS420J2 nyob rau hauv lawv cov ntsiab lus carbon: SUS420J1 muaj cov pa roj carbon ntau ntawm 0.16-0.25%, thaum SUS420J2 muaj cov ntsiab lus siab dua me ntsis ntawm 0.16-0.28%, uas ua rau me ntsis hardness thiab hnav tsis kam rau J2. Ob qib tuaj yeem raug kho cua sov (quenched thiab tempered) kom ua tiav siab hardness thiab yooj yim rau polish, ua rau lawv haum rau cov cuab yeej txiav, precision Cheebtsam, thiab cov ntaub ntawv zoo nkauj. Tsis zoo li cov qib austenitic, lawv tsis pom zoo rau cov tshuaj chloride hnyav lossis dej hiav txwv tab sis ua tau zoo hauv cov mob me me.

Mechanical Properties

Tensile Strength Ntau dua los yog sib npaug ntawm 620 MPa, Yield Strength Ntau dua lossis sib npaug ntawm 450 MPa, Elongation Ntau dua lossis sib npaug li 12%, Hardness Tsawg dua lossis sib npaug rau 223 HB (annealed); Tensile Strength Ntau dua los yog sib npaug rau 1050 MPa, Tawm Zog Ntau dua lossis sib npaug rau 750 MPa, Elongation Ntau dua lossis sib npaug li 8%, Hardness Ntau dua lossis sib npaug rau 302 HB (kub-kho, ob qib)

Qhov zoo

Zoo hardness thiab hnav tsis kam; zoo heev polishability; kub- kho tau; Sib nqus; zoo corrosion kuj tshaj SUS410 series; kev ua tau zoo sib npaug rau kev siv dav dav - lub hom phiaj coj - cov ntawv siv tiv taus.

Daim ntawv thov

Riam, hniav, cutlery, pwm, li qub, bearings, cov cuab yeej phais, cov khoom siv kho kom zoo nkauj, thiab cov neeg kho tshuab precision yuav tsum tau hnav tsis kam thiab tiv thaiv corrosion.

Qib sib npaug

SUS420J1: AISI 420, UNS S42000, EN 1.4021, GB 20Cr13; SUS420J2: AISI 420, UNS S42000, EN 1.4021, GB 20Cr13 (me ntsis carbon sib txawv)
