In line with the service concept of "honesty first, customer first" and the service tenet of "all for customer satisfaction", the company adopts the acceptance and response mode of combining manual and automatic, and accepts the diversified service demands of customer business consultation, complaint declaration, business acceptance, etc. through telephone, fax, e-mail, visit, letter, etc.
European standard high strength EN10025-6 S690QL steel plates are designed to provide excellent welding and bending properties. Due to its high strength, it enables design of lighter, more durable and efficient products and structures with S690QL steel plates and A709 grade 50W low alloy steel sheet.
20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. A709 grade 50W low alloy steel sheet, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.
It has good toughness. By strictly controlling the chemical composition, reducing the content of A709 grade 50W low alloy steel sheet 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, A709 grade 50W low alloy steel sheet using advanced technology and equipment, combined with high and scientific technical management, the material and shape of the product are even and consistent.
After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality.
