Hlau phaj, cov khoom siv tseem ceeb hauv kev lag luam niaj hnub thiab kev tsim kho, los ntawm ntau hom thiab cov khoom, feem ntau txawv ntawm cov khoom siv, lub zog, kev siv tshuab, thiab kev siv.
Raws li kev faib cov khoom siv, steel phaj tuaj yeem muab faib ua carbon steel, alloy steel, stainless hlau, thiab cov hlau tshwj xeeb. Cov pa roj carbon steel, feem ntau yog tsim los ntawm cov hlau thiab cov pa roj carbon, yog tsawg- tus nqi thiab yooj yim rau kev ua, ua rau nws siv dav hauv cov qauv tsim thiab tshuab tsim khoom. Alloy steel, txhim kho los ntawm kev sib ntxiv ntawm cov ntsiab lus xws li manganese, chromium, thiab npib tsib xee, txhim kho nws lub zog thiab kev tiv thaiv corrosion, ua rau nws tsim nyog rau kev thov xws li tsheb thiab nkoj. Stainless hlau, vim nws cov ntsiab lus chromium, tsim cov yeeb yaj kiab oxide, muab qhov tshwj xeeb corrosion tsis kam thiab feem ntau siv rau hauv qhov chaw huv lossis corrosive heev xws li khoom noj khoom haus thiab khoom siv kho mob. Cov hlau tshwj xeeb xws li hnav- tiv taus thiab tshav kub- cov hlau tsis muaj zog yog tsim los rau kev ua haujlwm hnyav, xws li siab- qhov kub thiab txias los yog cov tshuab mining.
Raws li qib zog, steel phaj tuaj yeem muab faib ua tus qauv lub zog (xws li Q235), siab zog (xws li Q355), thiab ultra-lub zog siab (xws li DP steel). Txheem- lub zog steel phaj yog tsawg- nqi thiab tsim nyog rau cov khoom tsis yog-load- cov kabmob. High- lub zog steel daim hlau, uas ua tiav cov load nce ntxiv- cov kabmob muaj peev xwm los ntawm kev tswj cov dov thiab kev ua kom txias lossis kev kho cua sov, yog siv dav hauv cov txuas hniav thiab cov tsev siab - nce siab. Ultra- siab{14}} lub zog steel yog siv rau hauv tsheb sib zog thiab kev siv dav hlau, ntsuas lub zog thiab qhov hnyav.
Kev siv thev naus laus zis kuj tseem cuam tshuam rau steel phaj kev ua haujlwm. Kub-rolled steel daim hlau yog tsim los ntawm siab -kub dov, ua rau ib tug ntxhib nto tab sis zoo heev toughness. Lawv feem ntau siv rau hauv cov thawv thiab cov kav dej. Txias- dov steel daim hlau yog ua tiav ntawm chav tsev kub, ua rau nyias nyias thiab ib tug smoother nto, ua rau lawv haum rau cov khoom vaj tse los yog precision Cheebtsam. Tsis tas li ntawd, galvanized steel daim hlau, nrog lawv cov xeb- tiv taus txheej, feem ntau yog siv hauv cov vov tsev lossis cov khoom siv hluav taws xob.
Hauv cov ntsiab lus, qhov sib txawv ntawm cov hlau phaj ncaj qha cuam tshuam rau lawv cov ntawv thov scenarios. Cov khoom siv tshuab, kev sib raug zoo ib puag ncig, thiab cov nqi tsim nyog yuav tsum raug txiav txim siab zoo thaum xaiv cov khoom siv los xyuas kom meej qhov sib tw ntawm cov khoom siv thiab cov kev xav tau ntawm qhov project.
