SM490YA SM490YB Carbon alloy steel plate

SM490YA, SM490YB belongs to the Japanese standard low alloy high strength steel, SM490YA low alloy steel, SM490YB low alloy steel material implementation standard for JISG3106 special technical conditions, SM490YA high strength low alloy steel SM490YA high strength low alloy steel, SM490YB high strength low alloy belongs to the high-strength structural steel, usually in the machinery manufacturing industry more applications, such as; machinery and equipment, heavy machinery, vehicle equipment, lifting machinery, mining machinery, coal mining machinery and equipment.

 

SM490YB high strength steel has high strength, good corrosion resistance, good weldability and cold forming. At the same time, it also has excellent low temperature toughness. After low-temperature impact test and overpressure test, it has stable performance and can withstand large dynamic loads and wave impacts. In the shipbuilding industry, SM490YB high strength alloy steel is commonly used to manufacture hulls, plates, keels, gun shafts and propulsion systems and other components. In marine engineering, it is also widely used to manufacture offshore platforms, submarine pipelines and marine facilities.
