JIS G3106 SM490YB steel plate is a low-alloy high-strength steel with a strength σb not less than 490MPa. The carbon content of SM490YB steel is maximum 0.20.
Carbon (C): Carbon content in SM490YB steel increases, yield point and tensile strength increase, but plasticity and impact properties decrease. When the carbon content exceeds 0.23%, the welding performance of steel deteriorates, so low alloys used for welding Structural steel generally does not contain more than 0.20% carbon. High carbon content will also reduce the atmospheric corrosion resistance of steel, and high-carbon steel in the open stock yard is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of steel.
Scope of application of SM490YB steel plate:
SM490YB is used in bridges, ships, vehicles, petroleum storage tanks, manufacturing plants, general construction and various engineering machinery, such as drilling rigs, electric shovels, electric wheel dump trucks for mining and various engineering constructions, and mining Automobiles, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment and other structural parts.
What we can do:1. Provide Z-direction performance Z15-Z35, impact performance and other special technical requirements, and achieve flaw detection.
2. The width is 1500-4020mm, the length is 18800mm, and the thickness is 8-650mm.
3. Provide cutting, drilling, grinding, zero-cutting according to the drawings, and other materials can be directly contacted
