The development S690QL rockwell hardness of the company comes from the resource advantage, service advantage, logistics advantage and brand advantage established over the years, and it is also inseparable from the full support of new and old customers. We will uphold the support of all sectors of society, actively provide users with S690QL rockwell hardness high-quality and efficient services, work together for win-win, and create a better tomorrow!

ASTM A514 steel plate is a high yield strength, quenched and tempered alloy steel plate suitable for welding. A514 steel plate has high strength, and S690QL rockwell hardness it can maintain mechanical properties even at very low temperature. At the same time, A514 steel plate also has good fatigue resistance, high toughness and low brittleness transition temperature, good cold forming performance and welding performance, good corrosion resistance and certain wear resistance.

Corrosion resistant steel is a kind of steel which can resist corrosion in air or weak medium and other strong corrosive medium. Corrosion resistant steel is also a kind of stainless steel. The corrosion resistance of corrosion resistant steel is better than that of stainless steel. S690QL rockwell hardness, Corrosion resistant steel has good machinability and high corrosion resistance in normal indoor environment. In the project, it can be used for its good corrosion resistance, and can be cut into steel with desired shape at will.

Medium and high carbon alloy hot rolled plates are mainly used in cold rolling and calendering, saw blades and tool industries. The company has taken advantage of smelting, hot rolled S690QL rockwell hardness plate and coil finishing equipment and technical advantages, and has successfully developed a batch of high-carbon and its alloy steel and medium-carbon high-alloy S690QL rockwell hardness steel hot-rolled coils with the goal of replacing imports. The iron oxide scale is delivered and trusted by high-end users.
