TFS Chrome Steel Plate Steel

OVERVIEW

TFS Chrome Plate Steel Overview and Characteristics

TFS (Tin-Free Steel) is a steel material that is coated with a metal chromium layer and a chromium oxide film on the surface of a cold-rolled thin steel plate by electrolytic deposition. Unlike traditional tin-plated steel plates (tinplate), its chromium layer cannot be remelted to form a bright surface, so a special chrome coating production line is required. Its technical standards include JIS G3315, ASTM 657, GB/T 24189-2009, etc. Steel types include MR, SPCC, TYPEL, thickness range 0.14-0.50mm, width 600-1050mm, coating weight is 50-150mg/m² of metal chromium, 5-35mg/m² of chromium oxide, and the surface can be passivated to present a bright, stone-grained or silver appearance, and coated with DOS oil for rust prevention

Application areas of TFS Chrome Plate steel

1. Packaging container field: It can be used to manufacture various metal packaging containers such as tea cans, coffee cans, gift boxes, cigarette boxes, etc. For example, 0.23mm thick TFS chrome-plated steel plate can be used for printing and making cigarette boxes, gift boxes and tin canstin boxes, etc. At the same time, because of its food-grade properties, it is also suitable for food packaging containers such as beverage cans, and can partially replace tinplate.

2. Industrial manufacturing field: It plays an important role in the production of metal packaging. Tianjin SWKD Metal Materials Co., Ltd. and other companies apply it to the construction of metal packaging bases, which can improve the quality and competitiveness of packaging products.


Production and processing of TFS Chrome Plate steel

1. Production process: The production needs to undergo cold rolling and other process treatments, and the surface treatment uses chrome plating and chromium oxide film covering technology. Tianjin SWKD Metal Materials Co., Ltd. is equipped with internationally advanced platemaking equipment such as Kodak CTP system, and has 8-color and 6-color UV metal printing production lines, which can print and process TFS chrome-plated steel plates

2. Processing characteristics: It has good printing performance and is suitable for multi-color UV metal printing, which can meet the design requirements of different packaging products. Its temper is divided into single rolling (T1-T5) and double rolling (DR8-DR9-DR10), and the appropriate specifications can be selected according to the specific application scenario.
