The hardness value of NM600 wear-resistant steel plate reaches 600 HBW, and it is generally used in extremely severe wear occasions, and mainly used to replace cast steel, chromium alloy cast iron and surface hardening metal A514 Gr P QT steel plate. Although the hardness of NM600 wear-resistant steel plate is very high, we can machine, weld and cut it. Although the hardness of NM600 wear-resistant steel plate is very high, it still has high impact toughness.
The company attaches great importance to systematic management, and has passed the A514 Gr P QT steel plate ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on A514 Gr P QT steel plate quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.
S355NC steel offers excellent bending, flanging, cold-bordering and folding A514 Gr P QT steel plate properties in both longitudinal and transverse direction. The bending radii specified below should be observed as minimum values.
With the increase of temperature, the yield limit of A514 Gr P QT steel plate will decrease monotonically, but the tensile strength of A514 Gr P QT steel plate will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of A514 Gr P QT steel plate. Near the blue brittleness temperature, the A514 Gr P QT steel plate strength increases and the plasticity decreases. The elongation and section shrinkage of A514 Gr P QT steel plate increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
