Product Description

T370HBW hardening high toughness low alloy steel ballistic steel plate

 

Description

Rolled homogeneous armor for vehicles.

T370HBW Class 1 ballistic steel is a rolled homogeneous armor plate (RHA) that combines good resistance to penetration with excellent toughness.

 

Benefits of T370HBW Class 1 ballistic steel include:

• Market-leading steel protection

• Superior workshop properties

• Optimized solutions

• Expertise in ballistic protection from VANFORGE

 

T370HBW Class 1 ballistic steel is not intended for further heat treatment.

 

Dimension range

T370HBW Class 1 ballistic steel is available in thicknesses between 3.0 and 100.0 mm. Other dimensions to be agreed with VANFORGE.

(1) Average of three tests. Transverse to rolling direction. Single value min. 70% of specified average.

(2) For plate thicknesses under 12 mm sub-size Charpy-V specimen are used. The specified minimum value is then proportional to the specimen cross-section.

 

Mechanical Testing

Brinell hardness test according to EN ISO 6506-1 on each heat treatment individual.

Charpy impact test according to EN ISO 148 on each heat and thickness from 6 mm.

Tensile test according to EN ISO 6892 on each heat and thickness under 60 mm.

 

Ultrasonic testing

According to EN ISO 10160 Class E3 S3 for thicknesses up to 80 mm and E1 S2 for > 80 mm.

Fabrication and Other Recommendations

Welding, bending and machining

T370T Class 1 ballistic steel is not intended for further heat treatment. If T370HBW Class 1 steel is heated above 390 °C after delivery from VANFORGE no guarantees for the properties of the steel are given.

Nitriding or surface coating may be carried out if the temperature is below 390 °C.

Appropriate health and safety precautions must be taken when welding, cutting, grinding or otherwise working on the product. Grinding, especially of primer coated plates, may produce dust with high particle concentration.
