Professional 09CuPCrNi-B steel demand sheet suppliers in China

In recent years, in line with the development trend of iron and 09CUPCRNI-B steel demand steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which 09CUPCRNI-B steel demand are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This 09CUPCRNI-B steel demand alloy steel 09CUPCRNI-B steel demand still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.

Q690E high strength steel chemical composition: C: 0.08-0.15, Si: 0.17-0.37, Mn: 0.40-0.70, S: ≤0.035, P: ≤0.035, Cr: 0.30～0.60, Cu: ≤0.030, Ni: ≤0.030, V: 0.15-0.30, Mo: 0.25-0.35Q690E mechanical properties:Tensile strength σb (MPa): ≥440Yield strength σs (MPa): ≥225Elongation δ5 (%): ≥22Reduction of area ψ (%): ≥50Impact energy Akv (J): ≥78

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
