(1) Low carbon: Due to the high requirements for toughness, weldability and cold formability, its carbon content does not exceed 0.20%.
(2) Adding alloying elements mainly manganese.Adding a small amount of rare earth elements can desulfurize and degas, purify the steel, and improve toughness and process performance.
(3) Adding auxiliary elements such as niobium, titanium or vanadium: which is conducive to obtaining fine ferrite grains and improving the strength and toughness of steel .
(4)In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance.
