silver steel

[jbaron]

i have heard it's the same as 01 is this true?

if so i can oil harden it?

[Roger Gregory]

Silver Steel is not the same as O-1. It is more like W-2 in composition but all the recommendations I have seen say you should oil-quench rather than water-quench because of the thin sections we use when knifemaking.

Oh, and I moved the thread to the Cutlers Forge because it's an iron-pounding topic :D

Mike Lamprey has fun quenching silver steel - he does it in brine.



The water boils and then becomes still for a moment when the redness of the steel vanishes then, as the critical temperature is reached (where all the carbon atoms play musical chairs trying to find new seats to occupy) the steel starts to glow cherry red again and the water boils for a second time.

will it produce a nice hamon

I think it explains well enough what silver steel is, and how you can heat-treat it.

I have been informed that it is often used in Finland, for making puukko blades.

1.00% 0.30% 0.40% 0.35%

Silver Steel is a 1% carbon tool steel supplied centreless ground to close tolerances. Available in 1, 2 or 3 metre lengths. Non standard sizes can be produced to your specific requirements.

Hardening: Heat to 770/790°C and thoroughly soak. Quench into well agitated water or preferably a 10% brine solution.

Tempering: Heat uniformly and thoroughly at the selected tempering temperatures and hold for at least one hour. For your guidance refer to our colour charts for forging, hardening and tempering.

Uniform machining properties and consistent response to heat treatment.
(All genuine STUBS Silver Steel is to BS 1407 Analysis optional standard, with the addition of 0.4% to 0.5% chrome for uniformity of both machining and consistency of micro structure of hardening/tempering).





Extensive Range of Diameters
Reduces machining costs considerably.
By choosing the right size for a particular job, much preliminary machining can be eliminated.




Exceptional Surface Finish
Eliminates grinding or polishing
The exceptionally high surface finish of genuine STUBS Silver Steel can be utilised without the need for further expensive grinding or polishing.




Controlled Annealing
Maximum degree of spheroidisation
Easier, more uniform machining is possible giving greatly improved machined surface.




Three Standard Lengths
A length to suit the job in hand.
Short lengths (333mm) for ‘one off’ jobs. Longer lengths (1 metre and 2 metres) for repetition machining.




Chamfered Ends
Prevent scratching.
All ends of genuine STUBS Silver Steel are deburred. This protects other lengths from scratching and ensures safety in handling. Look for the bars marked STUBS.

Bars Marked Stubs

i have a bar of silver steel from Stubs

[PS_Bond]

Colin - would you *please*point me to where on earth in the Parker catalogue O1 is listed? I've looked and looked, but I cannot for the life of me see the blasted stuff.

And no, I don't think this requires a poll :)

[Colin KC]

I think it does:D

OK Jon (BTW, I got the wood this morning, cheers)

But I'll not be getting any before Christmas I shouldn't think.

[jbaron]

thats ok i have some reserves, i thing i'm going to make some hunters with that sliver steel. perhaps clay backed, do you leave the clay on during the temper?
