SM490 SM490YA SM490YB SM490A SM490B SM490C High Strength Steel Plates

​

SM490 high strength low alloy steel is a Japanese standard low alloy high strength structural steel plate, which is produced according to JISG3106 standard. SM490 high strength alloy steel includes multiple varieties, such as SM490A, SM490B, SM490C, SM490YA, SM490YB, etc.,

and each steel plate has different performance and application fields.

SM490 low alloy structural steel has excellent mechanical properties, and the elongation has different requirements according to different thicknesses. For example, when the thickness is 16-40mm, the elongation is ≥21%; when the thickness is ≥40mm, the elongation is ≥23%. At the same time, SM490 steel plate also has good impact toughness and low temperature toughness, and can withstand large dynamic loads and wave impacts.

SM490 high tensile steel is widely used in many fields such as construction, bridges, ships, vehicles, oil storage tanks, containers, etc.
