Distinctive feature & main attribute: an improved rust- and acid-proofed chromium-nickel-molybdenum-steel alloy, precedingly refined by an electroslag remelting process (ESR), designed for components with increased chemical stability due to the quality standards ISO 5832-1 and ASTM F-138, nevertheless, it has a limited machinability and remarkable wear of tools.

Use & application range: this quality particularly meets the requirement of standard implants, implant screws and surgical instruments.

The watch industry found also an application field on external parts of watches, do to it’s improved polishing results, compared to standard AISI 316L (1.4404, 1.4435) steels.

You find it in different tensile ranges depending on the type of application. The hardness is only achieved by forced cold work.
