15N20 is basically a simple carbon steel also containing Nickel . Its primary use by bladesmiths, gunsmiths and other manufacturers of “Damascus “ pattern welded steel, is to provide a contrasting layer when forge welded to simple carbon steels. It can also be used like 1075 or 1084 as a cutlery steel in its own right. 15N20 is not supplied annealed.
Recommended Working Sequence For 15N20
Forging: to 1175 °C. Do not forge below 815 °C
Normalizing: Heat to 870 °C. Cool in still air. Follow up with further refinement cycles.
Annealing: Heat to 815 °C. Furnace cool to 650 °C at a rate not exceeding 28 °C per hour.
Grinding or Machining
Hardening: Austenitize- Heat to no higher than 815 °C. Quench in G-Quench or equivalent oil.
Tempering: As-quenched hardness of approximately 65 HRC. Hardness can be adjusted downward by proper tempering, recommended 200 °C
