Introduction

MR

The most general steel, steelmaking impurity residue less, excellent mechanical properties and corrosion resistance

L

Used for the production of acidic contents (oranges, yellow peaches, pineapples, etc.), and the inner surface of the food cans for iron high corrosion resistance tinplate substrate steel, such tinplate is often calledKPlate

D

Used to produce two pieces of high-processing tin plate substrate steel, such tin plate is often called.DIMaterial

SPCC

Chinese characteristics, using ordinary hot rollingSPHCProduces, usually used for miscellaneous tank purposes.

Features of TFS Chrome Coil

1. Coating structure: metal chromium layer (50-150mg/m²) and chromium oxide film (5-35mg/m²) composite coverage, providing corrosion resistance and coating adhesion.

2. Material standard: Comply with international standards such as ASTM, DIN, GB, JIS, etc., steel types include MR, SPCC, TYPE L, thickness range 0.14-0.50mm, width 600-1050mm

3. Surface treatment: Provides a variety of finishes such as bright (BA), stone (Stone), silver (Silver), etc., supports passivation treatment and DOS oil film protection


Processing advantages

1. Lead-free and environmentally friendly: Replaces traditional tin-plated steel plates, meets the safety requirements of food contact materials, and is suitable for scenes such as tea cans and food containers.

2. Forming performance: Supports stretching, stamping and other processing, BA (bright annealing) and CA (chemical treatment) surface treatments are adapted to different forming requirements


Application areas and industry value of TFS Chrome Coil

1. Food packaging: As a food-grade material, it is used in containers such as cans and beverage cans, and has acid and alkali resistance and corrosion resistance.

2. Industrial manufacturing: With its high-strength (High-strength Steel Plate) characteristics, it can be used for precision parts such as electronic component housings and battery housings
