SMA490BP steel for bridge construction Sheet Price

SA516Gr60 material, SA516Gr70, SA516Gr60N, SA516Gr70N steel plate in thickness ≤1.5in (40mm) is usually supplied in rolled state. The plate can also be ordered according to normalizing or stress relief, or normalizing plus stress relief. SA516Gr60 steel plate when thickness> 1.5in. (40mm) should be normalized. Unless otherwise specified by the customer, SMA490BP steel for bridge construction, SA516Gr60 steel plate (thickness ≤40mm) should be normalized when there is a notch toughness requirement.

The acicular ferrite pipeline steel can inhibit the formation of polygonal ferrite, promote the acicular ferrite transformation, and improve the precipitation strengthening effect of carbon and niobium nitride by adding molybdenum to reduce the transformation temperature of polygonal ferrite, so as to improve the strength of steel and reduce the ductile brittle transition temperature. The SMA490BP steel for bridge construction, tempered sorbite pipeline steel adopts the heat treatment process of quenching and tempering. The tempered sorbite structure is formed to meet the comprehensive requirements of thick wall, high strength and sufficient toughness.

Machining of SMA490BP steel for bridge construction, wear resistant steel plate: wear resistant steel plate has good cutting and shearing properties. During machining, the cutting tools and feeding speed should be used reasonably according to the hardness of steel plate. Common tools are made of high speed steel or cemented carbide steel, and carbide surface tools are required for grinding. Wear resistant steel plate can be welded to structural steel by arc welding.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
