GB / T1591 Q345D steel is a commonly used low alloy plate in China. It is equivalent to grade S355J2 in Germany and ASTM A529MGr50 in the United States, with slightly different chemical composition and the same mechanical properties. Under normal delivery conditions, Q345D steel equivalent to S355J2G3 in European standard, and even almost the same performance as the S355J2G4. They can be used interchangeably.

DC53 mold steel has better machinability and abrasiveness than SKD11. DC53 cold work die 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.

Titanium microalloying is an element of strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.

Q355GNH to GB/T 4171 steel sheet,LSAW Pipe to Peru. In the beginning of 2014, Peru government released an international tender for one of the hydroelectric power plant. Finally they chose us as the contractor, we purchased the steel plate and then fabricate the steel plate into steel pipe, and then make the corrosion protect on the surface, we also supply the fitting with our steel plate, the total value of this order is about 2 million USD.Q355GNH to GB/T 4171 steel sheet
