In the whole steel structure and steel body, the medium and heavy plate is an important part, once the problem occurs, it is easy to fracture, collapse and occur explosion. So how to judge whether the medium and heavy plate, SM490YA, USt37-2, SA572 hot rolled plate is of high quality? First of all, check whether there are cracks on the surface of the SM490YA, USt37-2, SA572 hot rolled plate plate and how glossy it is. Secondly, to measure the thickness error of medium and heavy plate, it is better to use the instrument to measure the bending tensile value. Finally, observe the scale of the steel plate manufacturers, whether there are relevant qualification certificates, and how the production process is.
The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of SM490YA, USt37-2, SA572 hot rolled plate nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of SM490YA, USt37-2, SA572 hot rolled plate steel, can be used as an alloying element of low alloy steel.
The pre cooling direct quenching and low temperature tempering of wear-resistant composite plate can reduce the quenching deformation of the workpiece, and the residual austenite content in the carburized layer can also be slightly reduced. The surface hardness of the hardfacing wear-resistant composite plate, SM490YA, USt37-2, SA572 hot rolled plate is slightly increased, but the austenite grain does not change. It is widely used in various tools of fine grain steel manufacturing.
With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel SM490YA, USt37-2, SA572 hot rolled plate product quality.
