4960 ton S700MC high strength alloy steel to Thailand

The shape defects of wear-resistant plates, S700MC high strength alloy steel mainly refer to various waves and buckles existing in continuous rolling mill products. The main reasons are the unbalanced load distribution of the racks, poor tension settings

The shape defects of wear-resistant plates, S700MC high strength alloy steel mainly refer to various waves and buckles existing in continuous rolling mill products. The main reasons are the unbalanced load distribution of the racks, poor tension settings between racks, and unreasonable work roll profiles. This kind of defect is easy to cause the adhesion phenomenon in the hood retreat, which has a great impact on the wear-resistant plates product quality. Edge defects are mainly caused by poor pickling trimming quality or poor plasticity of strip steel.

The Philiphine customer is our old customer, and they are engaged in offshore oilfield resources drilling projects. Thus they have regular steel demands. They ordered 1008 tons API 5L grade B ERW pipes and Q345B seamless pipes from us in April 2018. And told us that is a regular demand almost every two month. Since our first success cooperation, we have cooperated with each other regularly. And they also bring us new opportunities and signification in Philippians market.

Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the S700MC high strength alloy steel steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.

As leading EN10025-6 S460QL structural steel plates supplier in China, our company has supplied hundreds of thousands tons S460QL steel plates to clients to assist them finish one after another S700MC high strength alloy steel magnificent projects.
