Steel and Iron - Tool and die steels – Specification
Summry
Tool and die steels are high-quality alloy or carbon steels specifically designed for manufacturing tools, dies, molds, and cutting equipment. They offer excellent hardness, wear resistance, toughness, and dimensional stability at elevated and ambient temperatures, ensuring precision, long service life, and consistent performance in forming, cutting, and stamping operations.
Why BIS Certificate is Mandatory for Tool and die steels – Specification ?
BIS certification is mandatory to ensure tool and die steels conform to Indian Standards for chemical composition, mechanical properties, hardness, and heat-treatment characteristics. Certification prevents use of substandard steel that can fail under stress, guarantees product reliability, protects manufacturers and end-users, and ensures uniform quality across industrial and commercial applications.
What is BIS Certified for Tool and die steels – Specification ?
The BIS certified specification for tool and die steels defines chemical composition, mechanical properties, hardness, toughness, and heat-treatment requirements. It covers testing procedures, surface finish, dimensional accuracy, and internal soundness to ensure steels perform reliably in demanding operations such as cutting, stamping, extrusion, and molding, providing uniformity and safety in industrial use.
