Damasteel Stainless Steel Damascus – Gysinge™

Description

Damasteel Heat Treating:

This is phenomenal knife steel since the Chrome carbides are kept to a minute size by the manufacturing process. These are the cause of stress risers that initiate fracture points. If properly heat treated these two steels are many times stronger than other knife steels , show better edge holding and greater abrasion resistance.

Hardening:
1) Hardening temp. 1050⁰C. Hold time 12mins at temperature.
2) Quench rapidly between two cold metal plates.
This material is now stainless. It was not before hardening.
3) Deep cool (Liquid Nitrogen 45 minutes)

Tempering:
2 x 2 Hours
* 175⁰C. This will give hardness of 58 -59HRC.
Temper again for one – two hours. You can increase the temperature 20⁰C if the blades are too hard.

Etching Damasteel:
DO NOT ETCH WITH FERRIC CHLORIDE (Except for logo)
Etch with either HCL (Pool acid) as concentrated as it comes (37%) or H2SO4 (Concentrated Sulphuric acid 37% – car battery acid) Time depends on depth of etch required. Can range from 5 – 30minutes depending on the temperature of the acid.
Pool acid causes corrosion, store and use outside the workshop.

Logo Etching:
Best way to do a logo on any Damascus is to have it engraved or laser engraved.
If you wish to etch the logo, then use a super saturated solution of Ferric Chloride.(only for the logo!)
