Our quality control department will do inspection for details of the steel materials A573 Gr 70 steel and A516 Gr 70 carbon plate before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.
It has good toughness. By strictly controlling the chemical composition, reducing the content of A573 Gr 70 steel and A516 Gr 70 carbon plate 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, A573 Gr 70 steel and A516 Gr 70 carbon plate 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:①For low carbon steel, A573 Gr 70 steel and A516 Gr 70 carbon plate. 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.②For 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.③Normalizing 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.④Normalizing can refine the cast structure and improve the machinability of steel castings.
In January, 2019, our South Africa customer purchased 669 tons S235J2+N carbon steel plates to use in their tank fabrication project . S235J2 steel, as a non-alloy structural steel grade, is mainly used in structural projects and tanks. J2 symbol -20 temperature impact test. The client required CEV 0.38%, S≤0.01%, 100% UT, Charpy V-notch impact test at-20℃, Z25 for S235J2+N plates. After they receiving the S235J2+N steel plates, the customer are very satisfied with the quality of this batch of A573 Gr 70 steel and A516 Gr 70 carbon plate products.
