TATA TMBP (Tin Mill Black Plate) MR with T3 temper is a high-strength cold-rolled steel base plate used for tinplating, offering maximum hardness and rigidity, designed for applications requiring superior crush resistance and structural stability.

Key Features:

• Tensile strength ranging from 390–460 MPa and yield strength of 290–350 MPa, providing the highest strength among standard tempers for excellent can body integrity and stacking performance

• MR (Manufacturers’ Regular) grade ensures consistent chemical and mechanical properties for reliable tinplate manufacturing

• T3 temper indicates a hard temper condition achieved through increased cold rolling, ideal for pressurized or structurally demanding packaging

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

• Engineered as a substrate for electrolytic or hot-dip tin plating to produce high-performance tinplate for industrial and food-grade containers

Applications:
Carbonated beverage cans, aerosol containers, paint cans, closures
