SM490A Weather Resistant Steel JIS SM490A High-strength Structural Steel

SM490A Weather Resistant Steel Description

SM490A Weather Resistant Steel is a low alloy high-strength structural steel, and the SM490A steel plate complies with JIS G3106 standard. SM490A steel has excellent mechanical properties and reliable welding performance. SM490A has high mechanical properties, with a yield strength of over 325MPa and a tensile strength of over 490MPa, as well as good ductility and impact toughness. Such high performance can ensure the stability and reliability of the structure, and SM490A steel can support various complex engineering design and construction requirements.

JIS SM490A weathering steel has good welding performance, and SM490A steel can maintain stable welding quality. Widely used in the construction field in bridges, supports, and other pressure devices to ensure stable and reliable use over a relatively long period of time. SM490A steel plate is commonly used for cutting mechanical equipment components, as well as large welded steel structures. It can also be applied to bridge structures, large exhibitions, and high-rise building structures.

JIS SM490A steel plate is a structural carbon steel plate with good weldability, machinability, The thickness of SM490A steel plate can be used for Z properties: SM490A-Z15, SM490AZ25, SM490A-Z35, SM490B steel plate includes elements such as carbon, silicon, manganese, phosphorus, and sulfur. Among them, the content of carbon, manganese, and sulfur is lower, while the content of silicon and phosphorus is higher. The design of this chemical composition enables SM490B steel plate to have better malleability and high strength. SM490A low alloy structural steel is used for bridges, ships, vehicles, oil storage tanks, containers, and other welded components.
