Hello All,

I have just been looking at the cousinsuk.com website for gravers and they list two types of steel.

One is HSS which I am familiar with High Speed Steel the other is WS what is WS steel? Is this silver steel (drill rod US) that needs heat treating / tempering for use?

Cheers,
SRG

We always used silver steel indeed.
to be honest I also don't know what WS steel is....
Are these gravers pre formed?

nice day,
RJ van Melle.

No.

WS steel is water hardening (W), shock resisting (S) tool steel.

With WS steel it is easier to custom make your own profile cutters. Also, if you are going to work with soft materials (gold, silver, brass etc), WS is a better choice.

Werkzeug Stahl (german)
Makes sence: tool steel!
I used Google and came up on a german site explaining the kind of steel.

Not German.

AISI-SAE* steel grading system.

Water-hardening: W
Oil hardening: O
Air Hardening: A
High Carbon, High Chromium: D
Shock Resisting: S
High Speed, Tungsten base: T
High Speed, Molybdenum base: M
Hot working: H1–H19: chromium base, H20–H39: tungsten base, H40–H59: molybdenum base
Plastic Mold: P
Special Purpose: low alloy: L
Special Purpose, Carbon Tungsten: F


Germany uses DIN specifications; DIN 1.1654, 1.1663, 1.1673, 1.1744, 1.1645, 1.2206 or 1.2833 would probably be the equivalent, depending on the exact grade WS steel (W1, W2, etc) used.

Here is Japan we use HSS, pronounced in Japanese "Haisu" for gravers, but cobalt steel gravers are also available. I was trained on cobalt steel as at the time, it was thought that HSS would go out of use. Cobalt has it's uses, but is difficult to form or sharpen without a diamond wheel. Thanks for the information about WS Steel.
