Q345E steel plate is a low-alloy high-strength steel plate with good low-temperature impact performance The steel grade is composed of three parts: Q (Qufu in Chinese spelling) representing yield strength, yield strength value, and quality grade symbol Among them: Q represents the yield strength; 345 represents the yield strength value, unit MPa; E represents the grade (passed -40 degrees impact test),TB/T 1979 08CuPVRE steel sheet.

20G steel is a common carbon steel used to manufacture boilers. The performance of 20G steel is basically the same as that of 20# steel. The requirements for impact toughness, strain aging impact value and cold bending of 20G steel are increased. The yield ratio of 20G steel is slightly higher, and certain fatigue and corrosion resistance are required for 20G steel to ensure the safe operation of boilers. 20G steel is suitable for manufacturing marine boilers, steam boilers and other boiler accessories with pressure less than 6Mpa and wall temperature less than 450 ℃.

With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of steel material.

TB/T 1979 08CuPVRE steel sheet,Grade P295GH chemical composition under EN10028-2:2003 is displayed as follows. Chemical composition (C: 0.08 to 0.20; Cr: ≤0.30; Si: ≤0.40; Cu: ≤0.30;Mn: 0.90 to 1.50; Mo: ≤0.08;P: ≤0.025; Nb: ≤0.020;S: ≤0.015; Ni: ≤0.30;Al: ≤0.020; Ti: 0.03; N: ≤0.012; Vi: ≤0.02). The yield Strength MPa (min) of P295GH steel plate with thickness less than 16mm is 295MPa, and the tensile strength is 460-580MPa.
