1.4021 thiab 1.4301 Tus Hlau Stainless: Muaj peev xwm ua tau​

Nws1.4021Nws yog lub martensitic steel thiab tuaj yeem ua kom tawv los ntawm quenching thiab tempering, mus txog lub zog tensile ntawm600-850MPAthiab lub hardness ntawm48-52HRCCov. Hloov chaw, tus1.4301yog Austenitic,tsis tuaj yeem ua kom tawv tawv los ntawm kev kho cua sov, tswj xyuas qhov tsis muaj zog qis (70-90 hrb) tab sis muab kev sib txawv zoo thiab tawv. Qhov no ua rau1.4021Tsim nyog rau hnav-tiv taus thiab txiav cov ntawv thov, thaum lub1.4301Yog qhov zoo tshaj plaws rau cov qauv thiab kev txhim kho corrosion.

 

1.4021 thiab 1.4301 Tus Hlau Stainless: Hardness​

Nws1.4021tuaj yeem ncav cuag48-52HRCTom qab quenching thiab tempering, muab siab rau kev coj ua tau zoo thiab lub zog ntawm lub zog. Nws1.4301, ntawm qhov tod tes, feem ntau muaj lub hardness ntawm70-90 hrb, yog softer thiab ntau ducas. Lub siab tawv ntawm1.4021tso cai rau koj kom tswj cov npoo ntse thiab tiv thaiv kev puas tsuaj, thaum lub1.4301Nws yog qhov yooj yim rau daim ntawv thiab tshuab tsis muaj kev tawg.

 

1.4021 thiab 1.4301 Tus Hlau Stainless: Sib Nqus Khoom​

Nws1.4021, yog Martensitic, yoghlauOb leeg nyob rau hauv annealed thiab Hardened Tebchaws, uas tso cai rau nws kom pom nrog cov hlau nplaum thiab ua rau nws haum rau cov ntawv thov uas xav tau cov khoom sib sib sib nqus. Nws1.4301, zoo li cov roj av austenitic, yogtseem ceeb tsis yog sib nqusNyob rau hauv annealed xeev, txawm hais tias nws yuav qhia me ntsis magnetization tom qab ua haujlwm txias. Qhov sib txawv no yog qhov tseem ceeb thaum xaiv cov ntaub ntawv rau cov cuab yeej siv tau los sib nqus.

 

1.4021 thiab 1.4301 Tus Hlau Stainless: Corrosion Kuj​

Nws1.4301pubzoo heev corrosionVim nws cov chromium siab (17-19%) thiab npib tsib xee (8-10.5%) cov ntsiab lus, ua haum rau cov tubrog nkoj, tshuaj lom neeg thiab zaub mov qib ib puag ncig. Hauv kev sib piv, tus1.4021Nws muaj qhov sib zog tiv thaiv nrog 12-14% chromium thiab qis npib tsawg, yog li nws tuaj yeem oxidize hauv kev txhoj puab heev lossis chloride ib puag ncig. Tsim kho tshav kub kom zoo thiab nto kev ua tiav tuaj yeem txhim kho lub zog ntawm lub1.4021Cov.
