Nickel Alloy Steel 15N20 – 1.5 x 400 x 1200mm

Description

Nickel Alloy Steel 15N20 – 1.5 x 400 x 1200mm

15N20 is 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.
