1. Cov khoom siv sib txawv
Carbon steel:
Nws yog cov khoom siv hlau-carbon alloy uas muaj cov pa roj carbon sib txawv (feem ntau tsawg dua 2%), nrog rau manganese, silicon thiab lwm yam khoom. Nws qhov kev ua tau zoo yog hloov kho los ntawm qhov sib ntxiv ntawm cov ntsiab lus alloying, xws li nce hardness, lub zog thiab corrosion kuj.
Galvanized hlau:
Nws yog tsim los ntawm galvanizing zoo tib yam hlau. Nws txheej txheej yog zinc, uas tuaj yeem tiv thaiv cov khoom siv hlau los ntawm corrosion thiab oxidation, thiab muaj kev tiv thaiv corrosion zoo thiab muaj zog hnav tsis kam.
2. Cov txheej txheem ntau lawm
Galvanized hlau
Nws yuav tsum tau kub-dip galvanized thaum lub sij hawm tsim khoom, uas yog, zoo tib yam hlau yog immersed nyob rau hauv high-temperature molten zinc kua rau galvanizing. Hauv cov txheej txheem no, cov hlau yuav tsim cov zinc-hlau alloy txheej, uas muaj kev tiv thaiv corrosion zoo thiab cov khoom zoo nkauj.
Cov pa roj carbon steel
Nws tsis tas yuav kub-dip galvanized, thiab feem ntau yog tsim los ntawm ntau yam txheej txheem xws li high-frequency induction cua sov thiab converter refining.
3. Kev ua yeeb yam txawv
Cov pa roj carbon steel
Nws qhov kev ua tau zoo nyob ntawm nws cov ntsiab lus carbon thiab hom thiab cov ntsiab lus ntawm lwm cov ntsiab lus alloying. Feem ntau hais lus, qhov siab dua cov ntsiab lus carbon, qhov siab dua qhov hardness thiab lub zog ntawm cov hlau, tab sis cov yas yuav raug txo. Cov pa roj carbon steel muaj qhov tsis zoo corrosion kuj thiab nws yooj yim rau xeb hauv qhov chaw ntub dej.
Galvanized hlau
Lub ntsiab kom zoo dua ntawm cov ntaub ntawv galvanized yog lawv zoo corrosion kuj. Vim lub xub ntiag ntawm zinc txheej, cov hlau nto tuaj yeem tiv taus qhov yaig ntawm cov pa thiab ya raws, yog li ua kom qeeb ntawm cov txheej txheem corrosion. Tsis tas li ntawd, cov khoom siv galvanized kuj muaj cov khoom ua haujlwm zoo dua thiab cov khoom siv vuam.
4. Kev siv sib txawv
Carbon Steel
Kev siv dav hauv ntau yam kev lag luam thiab kev tsim kho, xws li kev tsim cov khoom siv, kev tsim vaj tsev, txuas hniav, cov kav dej, thiab lwm yam. Carbon steel yog ib qho ntawm cov hlau feem ntau siv vim nws cov nqi qis thiab kev ua tau zoo.
Galvanized hlau
Galvanized cov ntaub ntawv feem ntau yog siv rau qhov yuav tsum tau muaj kev tiv thaiv corrosion, xws li hluav taws xob ncej, guardrails, cov ntaub ntawv vov tsev, tsheb qhov chaw, thiab lwm yam. Galvanizing tuaj yeem txuas ntxiv lub neej kev pab cuam ntawm cov khoom steel, tshwj xeeb tshaj yog nyob rau hauv cov av ntub lossis corrosive ib puag ncig.
Feem ntau, ob qho tib si muaj lawv tus kheej cov yam ntxwv thiab daim ntawv thov, thiab kev xaiv ntawm cov khoom siv yuav tsum tau txiav txim siab raws li kev siv tshwj xeeb thiab ib puag ncig.
