The company adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the P355GH boiler steel inventory production and life style of saving, environmental protection, civilization and low carbon, adheres to the new industrialization road and the sustainable development road. Actively carry out international trade and maintain stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, the United Kingdom, Japan, South Korea and Australia.

Cold-rolled strips are widely used, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, food cans. Cold rolled steel sheet is the abbreviation of ordinary carbon structural steel cold rolled plate, p355gh boiler steel inventory, also called cold rolled plate. The cold-rolled plate is a hot-rolled strip of ordinary carbon structural steel, which is further cold-rolled into a steel plate with a thickness of less than 4mm.

The p355gh boiler steel inventory, wear-resistant steel plate has the characteristics of high strength, impact resistance, beautiful appearance, high performance, high efficiency, and high cost performance, and has a broad application prospect. The wear-resistant steel plate adopts a combination of plate and beam as a whole to carry a fully welded structure. Since the plate used is thinner, in order not to reduce the strength of the plate and reduce the deformation, try to use spot welding to form a cavity, which is the structural feature and technical key of the wear-resistant steel .

p355gh boiler steel inventory, Special thick steel plate cutting needs to be preheated in advance. Some steel plates are prone to cracks after entering the cutting process, sometimes that is because the temperature is too low, and it is necessary to perform pre-heat treatment in advance for such cases. The staff can preheat the steel plates first, so that the temperature of the steel plates will gradually increase, and then the flame gun can be used to cut. The probability of cracks in the cut material is very low, and the quality of the steel plate is also guaranteed.

As for Q460 series low alloy steel, there are three quality Grade C, D, E. p355gh boiler steel inventory, Q460C steel plates are mainly used in various large-scale engineering structures and light-weight structures that require high strength and large load. Q460C steel mechanical properties: Q460C yield strength MPa in different thickness: ≤16mm: ≥460; 16-40mm: ≥440; 40-63mm: ≥420; 63-80mm: ≥400; 80-100mm: ≥400; 100-150mm: ≥380. The tensile strength MPa: 550-720.Elongation: ≥17%.Impact test: 0 ℃ impact test: ≥34J.
