Nyob rau ntau lub sijhawm tib neeg xaiv cov hlau ntau dua li cov hlau tsis yog carbon steel feem ntau muaj cov hauv qab no.

(1) Tsis zoo hardenability

Cov pa roj carbon steel siv dej quenching, nws qhov tseem ceeb quenching txoj kab uas hla mus rau 15 ~ 20mm, 20mm txoj kab uas hla ntau dua rau qhov chaw, txawm tias cov dej tsis tuaj yeem quench hardenability, tsis tuaj yeem xyuas kom meej tias tag nrho cov seem kom tau txais cov khoom zoo tib yam.Yog li, rau qhov xav tau loj, carbon steel yeej tsis siv.Cov hlau muaj siab hardenability, tuaj yeem siv rau hauv kev tsim cov ntoo ntoo loj loj ntawm cov khoom nyuaj.

(2) Lub zog kub-kub, qis carbon steel, liab hardness txawv

Thaum cov pa roj carbon-carbon steels ntawm qhov kub siab tshaj 200℃, nws lub zog thiab hardness yuav sai sai no txo.Qhov zoo stability tom qab tempering steel.Liab hardness, thiab tuaj yeem ua haujlwm ntawm qhov kub thiab txias.

(3) Tsis muaj kev ua tau zoo tag nrho

Piv txwv li, thaum siv quenching los sim kom tau ib tug zoo tag nrho cov kev ua tau zoo, kom ntseeg tau tias siab zog, toughness yog tsawg, kom ntseeg tau zoo toughness, qhov siv ntawm sab qis.Qhov no yog vim tsis zoo stability ntawm carbon steel tempered vim li cas.Yog li ntawd, qhov tshwm sim carbon steel alloy tsis zoo tag nrho kev ua tau zoo ntau dua li ntawm cov hlau alloy muaj zoo toughness.

(4) Tsis muaj cov khoom tshwj xeeb

Piv txwv li, yuav tsum tau kub hardness los yog tonicity, anti-oxidation, corrosion kuj, tshwj xeeb hluav taws xob, sib nqus, thiab lwm yam., tsis tuaj yeem tau nrog carbon steel, alloy steel tuaj yeem xaiv kom tau raws li cov kev xav tau saum toj no.

Cov pa roj carbon steel kuj muaj qee qhov zoo, xws li los ntawm kev hloov nws cov ntsiab lus carbon thiab kev kho cua sov kom txaus, tuaj yeem tau txais hauv ntau qhov kev tsim khoom tsim nyog.Vim tias qhov tsawg carbon steel ntau lawm, tus nqi, yooj yim, kev ua haujlwm zoo, kev lag luam tseem yog cov khoom siv hlau siv dav tshaj plaws, suav txog ntau dua 80% ntawm tag nrho cov hlau.

Txhawm rau them nyiaj rau qhov tsis zoo ntawm carbon steel, carbon steel cable nyob rau hauv lub hauv paus ntawm consciously ntxiv ib co alloying ntsiab, yuav tsum tau kom tau ib tug ntau yam ntawm alloy zog.Thaum cov hlau muaj qhov zoo heev lossis tshwj xeeb, nws yog cov hlau tseem ceeb heev, tuaj yeem hloov kho raws li qhov xav tau ntawm thaj chaw, tab sis muaj ntau qhov tsis zoo ntawm cov hlau, feem ntau yog cov hlau alloying, cov hlau smelting thiab kev ua haujlwm tsis zoo dua li carbon steel, tus nqi yog kim dua.Raws li lub hauv paus ntsiab lus ntawm kev xaiv tsim nyog, thaum cov pa roj carbon steel ua tau raws li qhov yuav tsum tau ua, koj yuav tsum sim siv cov pa roj carbon steel.
