Cov qhab nia no yog tsiag ntawv los ntawm cov ntsiab lus carbon tsawg thiab zoo heev tsim nyog, ua rau lawv haum rau kev sib sib zog nqus duab thiab kev sib sib zog nqus. Hauv qab no yog cov lus qhia ntxaws heev:

1. Qib kev faib tawm thiab cov khoom tseem ceeb

Cov kawm hauv cov qib poob hauv qabEn 10130: 2006Txheem (khaub thuas-rolled low-carbon steel ntawv thiab strips rau kev txias ua), categorized los ntawmmuaj meej(los ntawm qis rau siab):

 

St12: General Txias Tsim Zoo.

St13: Zoo formability (txhim kho ductility).

St14: Sib sib zog nqus cov khoom zoo (ua qauv zoo dua thiab qhov chaw ua tiav).

Cov Nta Tseem Ceeb:

 

Cov pa roj carbon tsawg: Tsawg dua lossis sib npaug rau 0. 10% carbon kom ua kom muaj zog mos thiab ductility rau kev ua haujlwm txias.

Tsawg Alloy Ntsiab Lus: Feem ntau tsim ntawm Fe, C, MN, si nrog cov ntsiab tsawg kawg nkaus (tsis suav tias yog cov hlau qis dua hlau).

Nto Zoo: High-precision txias dov muab muab cov chaw du rau kev pleev xim lossis plating.
