DD14 steel for cold forming automobile Z35 plate products

Design of smelting composition and smelting process of SN400A, SN400B, SN400C steel, DD14 steel for cold forming automobile product: The smelting process adopts low-sulfur molten iron and low-sulfur scrap on the basis of the general process flow of steel

Design of smelting composition and smelting process of SN400A, SN400B, SN400C steel, DD14 steel for cold forming automobile product: The smelting process adopts low-sulfur molten iron and low-sulfur scrap on the basis of the general process flow of steel for export, adding the refining process of LIIF furnace deep desulfurization and SiCa treatment. In this way, the sulfur content in the steel can be reduced, and the sulfide in the steel can be modified. Greatly improve the toughness of steel and improve the casting performance of molten steel, and increase the qualification rate of the tundish temperature to ensure smooth casting.

DD14 steel for cold forming automobile, q345r pressure vessel steel is an ordinary low alloy steel, which is commonly used for boiler and pressure vessels. The delivery status of Q345R pressure vessel steel is hot rolling or normalizing. The properties of Q345R pressure vessel steel are similar to those of Q345 steel (16Mn). The yield strength of 16mm steel plate is greater than 345 Mpa, the tensile strength is 510-640 Mpa, the elongation is more than 21%, and the zero degree V-shaped impact energy is greater than 34J. The process reference standard of Q345R pressure vessel steel is GB713.
