Low Carbon
Due to the high requirements for toughness, weldability and cold formability, the carbon content does not exceed 0.20%.
Steel Searcher steel plate is a flat steel that is cast with molten steel and pressed after cooling.
It is flat, rectangular and can be directly rolled or cut from wide steel strips.The steel plate is divided according to the thickness, the thin steel plate is less than 4 mm (the thinnest is 0.2 mm), the medium-thick steel plate is 4-60 mm, and the extra-thick steel plate is 60-115 mm.
generally its yield strength is above 300MPa.
the elongation is required to be 15% to 20%, and the impact toughness at room temperature is greater than 600kJ/m to 800kJ/m. For large welded components, high fracture toughness is also required.
Good welding performance and cold forming performance.
Low cold-brittle transition temperature.
Good corrosion resistance.
Due to the high requirements for toughness, weldability and cold formability, the carbon content does not exceed 0.20%.
Add manganese-based alloying elements.
A small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of steel.
