Equal thickness tinplate is a cold-rolled tinplate with the same amount of tin plating on both sides. Tin plated sheet is made by rolling low carbon steel, followed by acid washing, cold rolling, electrolytic cleaning annealing, leveling, edge cutting processing, and then cleaning, electroplating, softening, passivation treatment, and oil coating before cutting into finished tin plated sheet metal.
Differential Thickness Tinplate Coil
Differential thickness tinplate is a cold-rolled electroplated tin plate with different tin plating amounts on both sides. Tin plated sheet is made by rolling low carbon steel, followed by acid washing, cold rolling, electrolytic cleaning annealing, leveling, edge cutting processing, and then cleaning, electroplating, softening, passivation treatment, and oil coating before cutting into finished tin plated sheet metal.
Tin Mill Black Plate (TMBP) steel is manufactured from hot rolled coils by pickling to remove the surface oxide produced during the hot rolling stage, and cold reducing through a cold mill to the desired thickness. TMBP produces a low ductility product that is usually processed further to develop desired end use characteristics.
ASTM A514 steel (also known as T1) grades incloud A, B, E, F, H, P, Q & S. This steel coil has a high yield strength and good weldability. ASTM A514 steel coil is quenched and tempered carbon-alloy steel. It is typically used when abrasion resistance and high-impact properties are required.
ASTM A516 covers carbon steel coils intended primarily for service in welded pressure vessels where improved notch toughness is important. According to different strength levels, the coils are available in four grades: Grades 55, 60, 65, and 70. The most common is Grade 70 or called out A516-70.
