T3 Hardness Tinplate Sheets

T3 hardness tinplate is a tin-plated thin steel plate with a higher hardness level. The tempering code is T3, the Rockwell hardness value (HR30T) is between 54-60, and the tensile strength is about 370MPa. It has undergone a cold rolling process, taking into account both strength and formability. It is suitable for general can bodies, can lids and packaging containers that require higher rigidity, such as electronic product shells, crown bottle caps, etc. The surface tin plating layer provides excellent corrosion protection, ensuring food grade safety, and is widely used in the metal packaging field of food, beverage, chemical and other industries.
