JIS SM490B plates carbon steel plate and sheet 100 tons stock

The steel such as JIS SM490B plates delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.

The company attaches great importance to systematic management, and has passed the JIS SM490B plates ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on JIS SM490B plates 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%.

S420NL-Z35 steel plate is alloy structural steel, and it implements the European standard EN 10025-3. The chemical composition of S420NL-Z35 steel plate: C:≤0.2, Si:≤0.6, Mn: 1 - 1.7, P:≤0.025, S:≤0.02. Delivery state of JIS SM490B plates, S420NL-Z35 steel plate: quenching + tempering. Of course, the delivery status can also be selected according to specific demands. However, it needs to be communicated between the supplier and the demander and indicated in the contract.

Common JIS SM490B plates, steel plate thickness specifications are as follows: Thick steel plate: thickness greater than 4, width within 10 is less than 2000mm, width above 10 is generally 2000, 2500mm, length 4-12m; Thin steel plate: thickness less than 4mm, width 500-1500mm, length 1.5-4m; Flat steel: thickness 4-60mm, width 12-200mm, length 3-9m.
