In order to prevent the from cutting cracks, preheating should be carried out before cutting. Special attention should be paid to preheating to make the entire JIS carbon steel SM490B CS plate interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole cannot be preheated, the partial preheating method can be used instead.The amount of Vanadium in steel material is generally between 0.04% and 0.12%. The role of Vanadium is to affect the microstructure and properties of steel material. It mainly precipitates in the ferrite at the austenite grain boundary, and can inhibit the recrystallization of austenite and prevent the crystal during rolling. The grains grow, which refines the ferrite grains and improves the strength and toughness of the steel material.JIS carbon steel SM490B CS plateJIS carbon steel SM490B CS plate,As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales.
