Cov ntsiab lus ntawm sulfur residual thiab cov ntsiab lus carbon nyob rau hauv cov hlau no feem ntau tsis tswj thaum lub sij hawm tsim khoom, thiab cov khoom siv tsis tuaj yeem taug qab mus rau qhov chaw, txawm tias hauv cov khoom siv rov ua dua tshiab. Yog tias Cr-Mn steels tsis tau teev tseg, lawv yuav dhau los ua cov khoom txaus ntshai ntawm cov khoom sib xyaw ua ke, ua rau cov hlau tsis muaj manganese siab heev.
