What is the difference between Q460NH seawater corrosion resistant steel material steel and mild steel?

The company has allocated special environmental protection facilities for all Q460NH seawater corrosion resistant steel material pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, Q460NH seawater corrosion resistant steel material steel mill scale, environmental protection dust has reached 100%.

SM400A/B/C steel structural quality carbon steel profiles, Q460NH seawater corrosion resistant steel material plates and bars used for riveting, bolting or welding of bridges and buildings and general structural purposes.

DC53 mold steel has better machinability and abrasiveness than SKD11. DC53 cold work die steel Q460NH seawater corrosion resistant steel material 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.

Temperature has a great influence on the strength of the material, Q460NH seawater corrosion resistant steel material. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.

Q460NH seawater corrosion resistant steel material, ASTM A131 shipbuilding steel has different grade levels. The ordinary strength shipbuilding steel grades are grade A/B/D/E. Their min. yield strength is 235 Mpa, and tensile strength is 400-520 Mpa. The higher strength shipbuilding steel grades are grade AH32/DH32/EH32/FH32, AH36/DH36/EH36/FH36 AH40/DH40/EH40/FH40. The min. yield strength of AH32/DH32/EH32/FH32 steel is 315 Mpa, and tensile strength is 440-590 Mpa. The min. yield strength of AH36/DH36/EH36/FH36 steel is 355 Mpa, and tensile strength is 490-620 Mpa. The min. yield strength of AH40/DH40/EH40/FH40 steel is 390 Mpa, and tensile strength is 510-650 Mpa.

The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, Q460NH seawater corrosion resistant steel material and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.

We have a professional after-sales department to collect all information related to customers, so as to make relevant treatment in time according to the information, and file it; guide the user's product use methods and precautions; coordinate with the sales department, visit customers regularly, understand the customer's use and new requirements, and make a customer visit record; When communicating with customers, they should be enthusiastic and careful to understand the situation of product problems and put forward solutions
