Europeean between PVQ A387 gr 11 boiler steel plate for hot rolled

Chinese grade of 20# steel plate: No.20
American grade: ASTM1020
Japanese grade: S20C
German, British and French grades: C22, C20C
Material No.: 1.0402, 1.0411

The strength of 20# steel plate is slightly higher than that of 15# steel plate, with little quenching and no tempering brittleness. , 20# steel plate is generally used for bending and so on processing. The welding performance of arc welding and contact welding is good. When gas welding, the 20# steel plate with thin thickness and strict or complex shape is easy to crack.PVQ A387 gr 11 boiler steel plate,The company adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the 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.PVQ A387 gr 11 boiler steel plate,Normalizing is a special case of annealing, the effect is similar to annealing, but the microstructure obtained by normalizing is finer. For low or medium carbon steel, normalizing can improve hardness and machinability. For medium carbon steel and low alloy steel, normalizing can refine grain and uniform structure and reduce hardness. For high carbon steel and high alloy steel, normalizing can eliminate the network carbide produced by forging and improve the homogeneity of the preparation heat treatment structure.
PVQ A387 gr 11 boiler steel plateMolybdenum 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 structural steel can improve mechanical properties. Molybdenum can also restrain the brittleness of alloy steel caused by quenching treatment.
