Txheej txheem cej luam ntawm hlau alloy
Alloy steel tuaj yeem muab faib ua: alloy steel qauv, uas yog siv los tsim cov khoom siv kho tshuab thiab cov qauv engineering; Alloy cuab yeej steel, uas yog siv los ua ntau yam cuab yeej; Kev ua haujlwm tshwj xeeb steel, uas muaj qee qhov tshwj xeeb lub cev thiab tshuaj lom neeg. Raws li kev faib tawm sib txawv ntawm tag nrho cov ntsiab lus ntawm cov ntsiab lus alloy, nws tuaj yeem muab faib ua: cov hlau tsis tshua muaj hlau, nrog rau tag nrho cov ntsiab lus ntawm cov ntsiab lus alloy tsawg dua 5%; (Medium) alloy hlau, tag nrho cov ntsiab lus ntawm alloy ntsiab yog 5-10%; High alloy steel, tag nrho cov ntsiab lus ntawm cov ntsiab lus alloy yog ntau tshaj 10%. Lub alloy steel yog tsuas yog siv nyob rau hauv lub sij hawm yuav tsum tau hnav tsis kam, corrosion kuj, kub tsis kam, tsis kub tsis kam thiab tsis muaj hlau nplaum.

Hom hlau
lHigh Tensile Strength Steels
Rau cov ntawv thov uas yuav tsum tau muaj zog tensile thiab toughness ntau dua li cov carbon steels muaj ntau yam ntawm cov hlau tsis tshua muaj hlau. Cov no yog categorized li high tensile los yog steels thiab rooj hardening steels. Lub siab tensile zog steels muaj txaus alloying ntxiv enabling los ntawm hardening (los ntawm quench thiab temper kev kho mob) raws li lawv alloying ntxiv.
lCase Hardening (carburising) Steels
Case hardening steels yog ib pab pawg ntawm cov pa roj carbon tsawg nyob rau hauv qhov chaw siab hardness saum npoo (li no lub sij hawm cov ntaub ntawv hardened) yog tsim thaum lub sij hawm kho cua sov los ntawm kev nqus thiab diffusion ntawm carbon. Qhov siab hardness tsam yog txhawb los ntawm qhov tsis muaj kev cuam tshuam hauv cov tub ntxhais hauv cheeb tsam, uas yog qis dua hardness thiab ntau dua toughness.
Cov pa roj carbon monoxide dawb uas tuaj yeem siv rau rooj plaub tawv yog txwv. Qhov twg siv cov pa roj carbon monoxide, qhov ceev ceev quenching tsim nyog los tsim kom txaus siab hardness nyob rau hauv rooj plaub yuav ua rau distortion thiab lub zog uas yuav tsim nyob rau hauv cov tub ntxhais yog heev txwv. Alloy case hardening steels tso cai rau qhov yooj yim ntawm cov txheej txheem quenching qeeb kom txo qis kev sib txawv thiab cov tub ntxhais muaj zog tuaj yeem tsim tau.
lNitriding hlau
Nitriding steels tuaj yeem muaj qhov tawv tawv dua uas tsim los ntawm kev nqus ntawm nitrogen, thaum raug nitriding cua ntawm qhov kub ntawm 510-530 ° C, tom qab hardening thiab tempering.
High tensile steels haum rau nitriding yog: 4130, 4140, 4150 & 4340.
