SA516 Gr65 sheet is a carbon steel plate for medium and low temperature pressure vessels. It implements the ASME standard of the American Standard. It can provide a minimum thickness of 8mm and a width of 1500~4000mm. The HARDOX 400 material hardness product thickness direction (Z-direction) resistance to tearing and wet hydrogen sulfide corrosion can be added Performance (HIC+SSCC) steel. Steel used to manufacture pressure vessels for petrochemical, gas separation and gas storage and transportation equipment.
It has good toughness. By strictly controlling the chemical composition, reducing the content of HARDOX 400 material hardness harmful elements and selecting reasonable heat treatment conditions, NM360 steel plate has good toughness. Therefore, the highly reliable structural parts can be constructed according to the brittle failure of wear-resistant components. Uniform and beautiful quality, HARDOX 400 material hardness using advanced technology and equipment, combined with high and scientific technical management, the material and shape of the product are even and consistent.
The main applications of normalizing are as follows:① For low carbon steel, HARDOX 400 material hardness. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.
Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. HARDOX 400 material hardness, Q420C steel has good mechanical properties and weldability, good cold and hot workability.
