What are the main factors influencing the price of JIS SM490B plates

30CrMnSiA steel is a grade of alloy structural steel. The steel has high strength and poor welding performance. It is a high-strength quenched and tempered structural steel with high strength and sufficient toughness after quenching and tempering, and good hardenability. It has good workability, small processing deformation and good fatigue resistance. 30CrMnSiA steel is mostly used to manufacture various important parts with high load and high speed.

JIS SM490B plates, Q345B low alloy plate performance: 1) High strength: Generally its yield strength is above 300MPa; 2) High toughness: The elongation is required to be 15% to 20%, and the room temperature impact toughness is greater than 600kJ/m to 800kJ/m. For large welded components, higher fracture toughness is also required; 3) Good welding performance and cold forming performance; 4) Low cold brittle transition temperature; 5) Good corrosion resistance.

As the thickness and hardness of JIS SM490B plates increase, the tendency to crack at the cutting edge increases. In order to prevent the JIS SM490B plates from cutting cracks, preheating should be carried out before JIS SM490B plates cutting. Special attention should be paid to preheating to make the entire JIS SM490B plates interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole JIS SM490B plates cannot be preheated, the partial preheating method can be used instead.
