EN-Engineering-Product-Hot-Rolled-Heat treatable steel-Steel strapping 30Mn5 Overview TSN
Tata Steel offers a choice of hot-rolled heat-treatable steel. Its chemical composition and the production processes we employ ensure robust, consistent products.
Manganese boron steel
Steel strapping
30Mn5 is a dedicated chemistry developed to produce straps and supplied as coil in hot rolled pickled.
Material is cold rolled at the customer to the required strip thickness, slitted to produce steel straps and heat treated (in some occasions also painted) to achieve the target microstructure and mechanical properties.
The application requires medium to high tensile strength, good ductility and work hardening.

EN-EngineeringAutomotive-Product-Hot-rolled-All grades Shape and dimensional tolerances TSE
Shape and dimensional tolerances
The specified values for wide strip do not apply to the uncropped ends of the coil (‘head’ and ‘tail’).
The length of these uncropped ends is calculated using the following formula:
length (in metres) = 90/nominal thickness (in mm), with a maximum of 20 metres.
If required, this part of the coil can be removed, however an additional cost may be charged for this.
Tolerances on thickness
Tata Steel can supply to full thickness tolerance specified in EN 10051:2010.

The tolerances for wide strip and slit wide strip comply with standard EN 10051:2010.
The specified values for wide strip do not apply to the uncropped ends of the coil (‘head’ and ‘tail’).
The length of these uncropped ends is calculated using the following formula:
length (in metres) = 90/nominal thickness (in mm), with a maximum of 20 metres.
If required, this part of the coil can be removed, however an additional cost may be charged for this.
