International Mold Steel has started stocking and processing Superplast® Stainless from the Industeel division of Arcelor Mittal. Superplast® Stainless is ideal for mold bases, holder block, un-etched/unpolished inserts and dies along with other applications where a high polish is not required.

The special chemistry, based on low Carbon and 12 percent Chromium content—provides good corrosion resistance in high humidity environments—the company states.

Superplast® is easily machined: milling, gun drilling, radial drilling and tapping due to its chemical composition, as compared to: W1-2085, W1.2316, and 420 F grades.

Features include:

  • Pre-hardened (30-35 HRC) 420 F-type material
  • Improved machinability
  • Improved consistency and weldability
  • Corrosion resistance

Superplast® is not designed for highly polished or textured surfaces. Material is available in plate form, and will be stocked up to 4 ¼”.
