The so-called after-sales service is to fully understand customers, study customer psychology, pay attention to after-sales details, improve work shortcomings, improve service quality, and Exchange customer brand loyalty through the whole process of quality service.
DC53 mold steel has better machinability and abrasiveness than SKD11. DC53 cold work die steel ASTM A709 bridge steel plate 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.
The requirements for toughness impact energy of ASTM A709 bridge steel plate, S355JR steel and S355J2 steel are different, other mechanical properties and various requirements are the same.S355JR steel toughness impact energy requirements: 20 ℃, impact energy ≥ 27JS355J2 steel toughness impact energy requirements: - 20 ℃, impact energy ≥ 27JAs the temperature decreases, the impact energy of the same steel will gradually decrease, so S355J2 steel is more expensive than S355JR steel.
Our company will accept the product quality objection registration record, pass it to the ASTM A709 bridge steel plate production unit and relevant departments, and timely coordinate the supervision of product ASTM A709 bridge steel plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
