TATA TMBP (Tin Mill Black Plate) DR-8 is a deep-drawing quality cold-rolled steel base plate with superior ductility, specifically engineered for severe forming operations and designed as a high-performance substrate for tinplating in complex can manufacturing.

Key Features:

• Tensile strength ranging from 250–320 MPa and yield strength of 140–210 MPa, providing a low yield-to-tensile ratio for excellent drawability and minimal earing during deep drawing

• DR-8 grade indicates deep-drawing quality with 8% reduction in area during cupping test, ensuring high deformation capacity without cracking

• Aluminum-killed, vacuum-degassed steel ensures fine grain structure, uniform properties, and resistance to aging

• Smooth, defect-free surface ensures strong adhesion of tin coating and compatibility with high-speed can-making lines

• Optimized for electrolytic or hot-dip tin plating to produce high-formability tinplate for intricate packaging shapes

Applications:
Two-piece food and beverage cans, deep-drawn containers, paint cans, and complex-shaped packaging requiring severe forming
