Based on the advantages of A131 AH36 naval engineering steel steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel A131 AH36 naval engineering steel products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .
A387Gr91Cl2 pressure vessel plate is equivalent to the Chinese grade 10Cr9Mo1VNbN steel. A131 AH36 naval engineering steel, A387Gr91Cl2 alloy steel plate not only has high oxidation resistance and high temperature steam corrosion resistance, but also has good impact toughness and high and stable durable plasticity and thermal strength performance. When the use temperature is lower than 620 ℃, its allowable stress is higher than that of austenitic stainless steel, A131 AH36 naval engineering steel.
DC53 mold steel has better machinability and abrasiveness than SKD11. DC53 cold work die steel A131 AH36 naval engineering steel is widely used in punching die, cold work forming die, cold drawing die; forming roll, punch; precision stamping die; precision cutting die for wire cutting and punching die for various purposes; difficult to process materials Tools for plastic deformation; cold forging, deep drawing and thread rolling dies; high-speed punching punches, stainless steel punches.
First to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of A131 AH36 naval engineering steel welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.
According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. A131 AH36 naval engineering steel, GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.
