We will make a billet with ~2 kg output from 120mm wide starting material especially for you. You can decide what thickness the finished steel should have and what the pattern of the steel looks like. The length is determined by the mass and the cross-section. If the billet is longer than 600mm, we have to divide it into two pieces of approximately the same size. Production takes place within 4-8 weeks from receipt of payment.
Developed and manufactured to high quality standards, this fire-welded steel is perfect for making high-hardness knives using the stock removal process. Thanks to its excellent toughness with a hardness range of 63-68 HRC, ApexUltra Nickel 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 the top layer.
We normalize, grain refine and anneal the steel after forge welding and forging/rolling to save you these time-consuming steps as a knifemaker 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 just grinding the surface.
We straighten the steels as best we can in this step. Fine straightening can still be beneficial after contour grinding and before hardening.
Recommended hardening: 830°C for 10 minutes, quenching in medium or fast oil. Temper at 175°C for 2x2 hours with cooling to room temperature before each tempering cycle. For more information on hardening, see the ApexUltra data sheet: [https://www.apexultrasteel.com/downloads].
The cutting layer makes up about 30% of the material thickness.
Small (<8mm) embossed markings may be found on the ends of the pieces to prevent confusion.
ApexUltra / Cu / 80CrV2 - Custom Billet
It is a raw material for making knives using the stock removal process. The pictures of the knives are merely examples of how this steel can be used; the knives are not part of the article offered here. The steels offered are not stainless. The copper contained can react with acidic foods when it comes into contact with them. Since this is a custom-made product, returns or exchanges are unfortunately not possible. Rolling tolerances: +/- 0.3 mm thickness, +5 / -0 mm in width
