Enhanced Mold Steel: Elevating Performance with Vanadium

Typically used for relatively low-temperature applications such as injection molds and synthetic plastic molds, it is particularly suitable for large molds in various industrial fields.

Industries in detail

Product advantages

This steel falls under the category of mold steels and offers increased hardenability compared to SIMOLD 2738. Vanadium additions enhance the achievable work hardness and improve tempering resistance. This grade provides a homogeneous hardness distribution, promoting good machinability, excellent polishability and suitability for texturing. It is also available as ESR remelted (SIMOLD S131 R) for higher polishability.

Hardness range

  • SIMOLD 2738: 280 - 325 HBW (approx. 29-35 HRc / 950-1100 N/mm²) 
  • SIMOLD S131: 310 - 360 HBW (approx. 33-39 HRc / 1050-1220 N/mm²) 
  • SIMOLD S133: 360 – 400 HBW (approx. 39- 43 HRc / 1220- 1360 N/mm²) 

Manufacture

SIMOLD S133 is made by SIJ Metal Ravne.
