NV F32 hull steel heavy plate chemical composition

NV F32 hull steel heavy plate,S355J2+N steel plate belongs to the European standard low alloy structural steel grade. S355J2 steel is equivalent to Q345D grade. NV F32 hull steel heavy plate, S355J2+N low alloy steel plate is widely used in bridges, vehicles, ships, building steel structures. Mechanical properties of S355J2+N steel: Yield strength: ≤16mm: ≥355; 16-40: ≥345; 40-63: ≥335; 63-80: ≥325;80-100: ≥315; 100-150: 295; 150-200: ≥285; 200-250: ≥275; 250-400: ≥265. Tensile strength: 450-680MPa.Our company is China's 10th largest supplier & Exporter of stainless steel, carbon steel plate and section, alloy steel plate and pipes We are specialized in stocking & distributing various Stainless Steel, carbon steel plates, angle steel, H beam steel to worldwide for specific & urgent requirements We have a fully advanced and modernized warehouse that stores tonnes of our value-adding products, which we source out from the mills that are compliant with the universal guidelines for plate production,NV F32 hull steel heavy plate.NV F32 hull steel heavy plate,Normalizing is a special case of annealing, the effect is similar to annealing, but the microstructure obtained by normalizing is finer. For low or medium carbon steel, normalizing can improve hardness and machinability. For medium carbon steel and low alloy steel, normalizing can refine grain and uniform structure and reduce hardness. For high carbon steel and high alloy steel, normalizing can eliminate the network carbide produced by forging and improve the homogeneity of the preparation heat treatment structure.
The effect of alloy elements of Q345B alloy steel plate on tempering transformation: improving the tempering stability. The alloying elements delay the decomposition of martensite and the transformation of residual austenite during the tempering process. Increasing the recrystallization temperature of ferrite makes it difficult for carbides to aggregate and grow, so the resistance of steel to temper softening is improved, that is, the tempering stability of steel is improved.The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
