Chrome-Moly low alloy steel A514 grade E structural steel material series contains 0.5% - 9% Cr and 0.5% - 1% Mo and lower than 0.20% carbon. 40CrNiMoA, 4340 and SNCM439 are the low alloy chromoly steel materials from the different standards. 40CrNiMoA steel A514 grade E structural steel material is a Chinese standard chromium-molybdenum high strength steel with good hardenability and toughness.
The main component of A514 grade E structural steel material manganese plate is manganese, which is a relatively powerful element type, and plays a more important role in long-term development and continuous use. The main characteristics of manganese plates are high hardness and high strength. For general manganese plates, it is necessary to enhance the compressive capacity of manganese steel plates and various basic corrosion resistance capabilities. For common manganese plates, pay attention to use, choose good specifications and classifications, thus the use value of manganese plates will be better.
A514 grade E structural steel material, Wear resistant steel plate has good temperature resistance: Wear resistant steel plate alloy carbide has a strong stability at high temperature, wear-resistant steel plate can be used within 500℃, and other special requirements can be customized. It can meet the conditions within 1200℃; ceramic, polyurethane, polymer materials and other wear-resistant materials can not meet such high-temperature requirements.
Weather-resistant steel is atmospheric corrosion-resistant steel. It is a low-alloy steel that has better corrosion resistance in the atmosphere than ordinary carbon steel by adding a small amount of alloy elements. Compared with A514 grade E structural steel material, weathering steel Q355NH, Q355GNHE weathering steel has better resistance to atmospheric corrosion. It is necessary to ensure that the steel plate has high strength and good plasticity and toughness. In addition, by adding a corrosion-resistant element to ensure the atmospheric corrosion resistance index I to reflect its good corrosion resistance.
