Q355NC material chemical composition

Q355NC material is a low-alloy high-strength structural steel. Q355NC steel is not only high-strength steel, it is also low-carbon steel. Q355NC steel has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion performance and certain wear resistance.
 
Q355NC material chemical composition (%)
C: not greater than 0.20 Si: not greater than 0.5 Mn: 0.90-1.65 P: 0.030, S: 0.030 Nb: 0.005-0.05 V: 0.01-0.12, Ti: 0.006-0.05 Cr: not greater than 0.30 Ni: not greater than 0.50, Cu : Not more than 0.40 Mo: not more than 0.10 N: not more than 0.015 Als: not less than 0.01
 
Q355NC material manufacturing method　　
Steel is smelted by a converter or electric furnace, and can be refined outside the furnace if necessary. Unless the buyer has special requirements and is indicated in the contract, the smelting method is generally chosen by the supplier.
