Developed and manufactured to high quality standards, this forge-welded steel is perfect for producing high-hardness knives using the stock removal process. Thanks to its excellent toughness in a hardness range of 63-68 HRC, the ApexUltra Nickel Go Mai surpasses other steels with such high hardness.

  •  Recommended hardness range of the cutting layer: 63-68 HRC. 5-layer steel with ApexUltra core layer, copper diffusion barrier and black-etching 80CrV2 as top layer.
  •  After forge welding and forging/rolling, we normalize, grain refine and anneal the steel to save you these time-consuming steps as a knife maker and to get the best possible performance from the steel. So you can start sawing or grinding the contour straight away.
  •  To bring out the natural texture of the steel, we gently remove the scale instead of simply grinding the surface.
  •  We straighten the steel as best as we can in this step. Further straightening can still be beneficial after contour grinding and before hardening.
  •  Recommended hardening: 830°C for 10 minutes, quenched in medium or fast oil. Temper at 175°C for 2x2 hours with cooling to room temperature before each tempering cycle. For further hardening advice, see the ApexUltra datasheet: [].
  •  The cutting layer makes up about 30% of the material thickness.

It is a raw material for making knives using the stock removal process. The pictures of the knives are just examples of how this steel can be used; the knives are not part of the article offered here. The steels offered are not rustproof. The copper they contain can react with acidic foods when it comes into contact with them.
