Sulphur yog los ntawm ore thiab roj coke hauv kev lag luam hlau. Nws yog ib qho khoom muaj mob hauv steel. Sulphur tshwm sim nyob rau hauv cov hlau uas yog hlau sulfide (FeS). FeS thiab Fe daim ntawv qis melting point (985 ℃) sib txuas. Qhov kub-ua haujlwm qhov kub ntawm cov hlau feem ntau tshaj li 1150 ～ 1200 ℃, yog li ntawd thaum cov hlau ua haujlwm kub, cov haujlwm ua haujlwm tawg vim lub sijhawm ua ntej melting ntawm FeS tebchaw. Qhov tshwm sim no yog hu ua 0010010 quot; kub brittleness 0010010 quot;. 0010010 nbsp;
Lub ductility thiab toughness ntawm cov hlau txo thiab cov kab nrib pleb tshwm sim thaum lub sij hawm forging thiab dov. Sulphur tseem ua teeb meem rau weldability thiab txo qhov ua hauj corrosion. Siab zoo steel: S 0010010 lt; 0. 02% ~ 0. 03%; high quality steel: S 0010010 lt; 0. 03% ~ 0. 045%; hom hlau: S 0010010 lt; 0. 055% ~ 0. 7%.
Vim tias nws daim tawv nyias tawg thiab tuaj yeem tau qhov chaw zoo nkauj, nws tuaj yeem siv los ua cov ntu steel nrog cov load qis thiab siab kawg npoo (hu ua nrawm-txiav steel), (xws li Cr 14) txhob txwm ntxiv me me ntawm leej faj (= 0.2-0. 4%).
