Tedious steps of yield strength of nm500 steel welding technology

The shape defects of wear-resistant plates, yield strength of NM500 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.

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 yield strength of NM500 steel 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 yield strength of NM500 steel steel hot-rolled coils with the goal of replacing imports. The iron oxide scale is delivered and trusted by high-end users.

By Region: data shows that in the first quarter of Asia, crude steel yield strength of NM500 steel production was 315.2 million tons, down 0.3% year on year. Crude steel production in the EU region in the first quarter was 38.3 million tons, down 10.0% year on year. The output of crude steel in North America in the first quarter was 29.5 million tons, down 4.0% year on year.

Welded steel pipes are made by crimping steel plates, bending them into a circle, and then welding the joints together. Seamless steel pipe is directly processed by round steel piercing or hot rolling process, so there is no weld on the outer surface. The performance of seamless steel pipe is better than that of welded steel pipe, and the price of seamless steel pipe is also higher. There are some differences in chemical composition between yield strength of NM500 steel, welded steel pipe and seamless steel pipe. The material of welded steel pipe contains the chemical composition suitable for welding.
