Our company's hot rolled P295GH steel power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the hot rolled p295gh steel utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

Fake and inferior steel plates are easy to scratch because of the simple equipment of the manufacturers of fake and inferior materials, which are easy to produce burrs and scratch the surface of the steel plate. Deep scratches reduce the strength of the hot rolled p295gh steel, steel plate. The surface of the fake and inferior material is prone to cracks, because its billet is adobe, which has many pores. The adobe is subjected to thermal stress during the cooling process, and cracks are generated, and there will be cracks after rolling.

hot rolled p295gh steel, SA533 GrB CL2 steel plate is an American Standard vessel steel plate, which is in accordance with ASME SA533 / SA533M. And it is quenched and tempered Mn-Mo and Mn-Mo-Ni alloy steel plate.The chemical composition of SA533 GrB CL2 steel plate is C: 0.25, Mn: 1.15-1.50, Mo: 0.45-0.60, Ni: 0.40-0.70, Si: 0.15-0.40, P: 0.012, S: 0.015, Cu: 0.10, V: 0.01.

On March 17, the Ministry of Finance and the State Administration of Taxation jointly issued the announcement on increasing the export tax rebate rate of some products, and the relevant adjustments will be implemented from March 20. This adjustment involves 60 tariff numbers of steel products. After the adjustment, the hot rolled p295gh steel etc. steel products with the original export tax rebate rate of 10% will be fully refunded, which is great news for both steel exporters and our customers.
