Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and P235GH steel plate resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, p235gh steel plate new materials, and promotes the competition of enterprises Struggle.

Hardox 600 steel is available in thicknesses of 6–65 mm. This product is available in widths up to 2000 mm and lengths up to 14630 mm. Preferred dimensions are 2000 x 4000 mm, other dimensions on request. Resistance to abrasive wear is not an intrinsic material property; it depends on the application. p235gh steel plate materials that exhibit superior abrasion resistance under one set of conditions might perform poorly under different conditions.

The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. p235gh steel plate, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.

The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by p235gh steel plate metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the p235gh steel plate steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.

20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. p235gh steel plate, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.
