BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of P355GH hardness property steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main p355gh hardness property production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

S235JR is a European standard non alloy structural steel, equivalent to the national standard Q235B, i.e. S235JR steel is carbon structural steel with low carbon content. S235JR steel is widely used in welding, bolt connection and riveting structures. S235JR steel is mainly used in railway, bridge, all kinds of construction engineering, manufacturing all kinds of metal components bearing static load and unimportant mechanical parts and p355gh hardness property general weldments that do not need heat treatment.

Wear resistant steel plate has high wear resistance and good impact performance. It can be cut, bent, welded, etc. This material p355gh hardness property can be connected with other structures by welding, plug welding, bolt connection, etc. Wear resistant steel plate has the advantages of saving time and convenience in the process of maintenance. It is widely used in metallurgy, coal, cement, electric power, mining, building materials and other industries. Compared with other materials, wear resistant steel plate has a high cost performance, and has been favored by more and more industries.

Molybdenum is a well known alloy element. Molybdenum can refine the grains of steel material, improve the hardenability and thermal strength, and maintain sufficient strength and creep resistance at high temperature. Adding molybdenum to p355gh hardness property, structural steel can improve mechanical properties. Molybdenum can also restrain the brittleness of alloy steel caused by quenching treatment.

Chemical composition of p355gh hardness property, Q345D steel plate: C: ≤0.18; Si: ≤0.50; Mn: ≤1.70; P: ≤0.030; S: ≤0.025; Nb: ≤0.07; V: ≤0.15; Ti: ≤0.20; Cr: ≤0.30; Ni: ≤0.50; Cu: ≤0.30; N: ≤0.012; Mo: ≤0.10; Als: ≥0.015. Yield strength (MPa) of Q345D steel plate: ≤16mm: ≥345; 16-40mm: ≥335; 40-63mm: ≥325; 63-80mm: ≥315; 80-100mm: ≥305; 100-150mm: ≥285; 150-200mm: ≥275; 200-250: ≥275; 250-400: ≥265. Tensile strength of Q345D low alloy steel: 450-630(MPa). Elongation: ≥21. Impact test: -20 ℃: ≥34.
