Edro, an exclusive U.S. distributor for Böhler, introduces the company’s newly developed M333 Isoplast stainless steel. Manufactured via a new melting technology, M333 offers moldmakers what is said to be best-in-class polishability, enhanced thermal conductivity, optimized toughness and exceptional corrosion resistance.
According to Edro, testing has shown M333 Isoplast to exhibit up to four times the toughness levels seen in 420 stainless steel and almost matching the toughness of H13. This enables molds to have the benefits of stainless steel without the risk of cracking.
M333 Isoplast’s chemistry and pressure electroslag remelting process also provides M333 enhanced thermal conductivity almost matching H13, ensuring faster cycle times up to 20% compared to traditional 420 ESR.
Further, the stainless steel’s primary and secondary carbides are significantly reduced by lowering the carbon content and optimizing chemical composition, Edro notes, resulting in improved microstructure. Combining this with M333’s P-ESR remelting process results in improved finishes and faster polishing times.
Finally, M333’s modified alloying composition improves corrosion resistance by reducing carbides and improving the free chromium within the steels matrix. M333’s double remelting process ensures a homogenous microstructure to give provide exceptional corrosion resistance.
