The company has allocated special environmental protection facilities for all ASTM A514 structural steel material pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, ASTM A514 structural steel material steel mill scale, environmental protection dust has reached 100%.
ASTM A514 structural steel material and SM490B steel plate belongs to low alloy high strength steel, which is a kind of structural steel produced according to Japanese Standard JIS G3106. Its strength σb is 490MPa. ASTM A514 structural steel material, SM490B steel plate is mainly used in buildings, bridges, ships, rail vehicles, oil storage tanks, containers and other buildings requiring advanced weldability.
As an important classification of steel, ASTM A514 structural steel material hot rolled steel coil has the following advantages: first, hot rolled steel coil can be curled at will, reducing the occupied space, and it is convenient for transportation. Second, the processing of hot rolled steel coil is flexible and convenient. For spiral welded pipe, coil uncoiling, leveling, trimming, forming and welding are used. For longitudinal welded pipe, it must be formed and welded with steel plate. The hot rolled steel coil price is affected by the size and specification. The prices of different specifications and thickness ASTM A514 structural steel material, hot rolled steel coils are different.
Both parties shall confirm the ASTM A514 structural steel material material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the ASTM A514 structural steel material steel plant.
