Explanation
steel with very low carbon content usually refers to steel with carbon content less than 0.03%. Carbon is an important alloy element in steel, which can significantly improve the strength and hardenability of steel, but has adverse effects on the toughness, weldability, deep drawing and corrosion resistance of steel. Therefore, steel with special requirements for toughness, deep drawing or intergranular corrosion resistance must use ultra-low-carhon steel with very low carbon content. T nitrogen has the same adverse effect on relevant properties, so ultra-low-carhon steel also needs to strictly control the nitrogen content in steel. Ultra-low-carhon steel is produced by using optimized raw materials and special refining process. Ultra-low-carhon steel includes ultra deep drawing steel, IF steel, extra low carbon stainless steel, etc.
