What is difference between Low alloy steel & high alloy steel and Fe-C Steel & C-Mn Steel ? Thank
Good explainatoion in Section 17 CSWIP WIS5-90516b:
Classification of Steels
- Low Alloy Steels <7% alloying elements.
- High Alloy Steels >7% alloying elements.
Alloy steels are considered the type of steels that predominantly contain extra alloying elements other than iron and carbon.
Types of weldable C, C-Mn and low alloy steels
- Carbon contents up to about ~ 0.25%.
- Manganese up to ~ 0.8%.
- Low strength and moderate toughness.
Manganese up to ~ 1.6%.
Carbon steels with improved toughness due to additions of manganese.
