Alloy Steels

EN 24 Alloy Steel

Approx Price: Rs 70 / Kilogram 
Our offered EN 24 Alloy Steel is a very popular grade of through-hardening alloy steel, which is readily machinable. Furthermore, this is capable of retaining good impact values at low temperatures; hence it is frequently specified for harsh offshore applications such as hydraulic bolt tensioner and ship borne mechanical handling equipment.

Features:

  • Enhanced wear resistance
  • High strength properties
  • Good edge retention

EN 19 Alloy Steel

Approx Price: Rs 48 / Kilogram 
Our offered EN 19 Alloy Steel offers good ductility and shock resisting properties combined with resistance to wear. With these characteristics, it is popular high tensile engineering steel and is also suitable for a variety of elevated temperature applications.

Features:

  • Maximum wear and abrasion resistance
  • Good ductility and shock resistant
  • Low maintenance

EN 31 Alloy Steel

Approx Price: Rs 55 / Kilogram 
Our offered EN 31 Alloy Steel offers a high measure of hardness with compressive strength and abrasion resistance. Its applications include taps, gauges, swaging dies, ejector pins, ball and roller bearings. It is a good quality steel for wear resisting machine parts and for press tools which do not merit a more complex quality.

Features:

  • Rigid construction
  • Excellent high carbon alloy steel
  • Wear-resisting machine constituents
