Translation to American required.

Silver steel is "drill rod" in US-English. Drill rod being of a bit better quality than silver steel.

Gunmetal is "red brass"

Silver steel is drill rod in american, for gunmetal try looking for "government bronze", link here

Thank you gentlemen. All 3 replies passed on to the ATIS list.

Of course you can take it one more step. I have seen material sold as drill rod made from any of several alloys. A2, D2, O1, S7, and W1 ________ Andre' B.

Drill rod and tin bronze (or silicon bronze?).

IIRC silver steel is/was plain high carbon steel equal to 1095 or

Gunmetal was the stuff cannons were cast of. Any decent bronze alloy is likely to work OK if the part is machined, get a decent casting alloy (everdur is one brand name of a silicon bronze) for melting and pouring.

The refractory dealers that I know of also deal in other foundry supplies, and thus, ingots of known alloy casting metals.

Silver steel is drill rod the water hardening variety is the same as silver steel. Free machining drill rod is not available where I live. Gun metal is Bronze, there are two alloys known as gun metal, both are difficult to find here in western Canada. :(

Are you sure? To my knowledge, it is a CrV alloy. It should be something like 1.2210 (115CrV3). With just C, you wouldn't get the "silver" in "silver steel".

I know that there are slight differences in the alloys compared to our Kraut-Silberstahl, your silver steel and the drill rod (A1?). But functional, they are all the same and in the same ballpark alloy-wise: A cutting steel for cold working. Like making reamers, mills (for short runs), D-bits, crown-bits, etc.

I have seen several refs in Model Engineer that said that or similar.

As far as the applications that called out silver steel that I have seen, a plain, water hardening, carbon steel looked like the best pick AFAICT.

I could well be off base a bit, but as far as available sources for the applications, water hardening drill rod is the closest I can reliably obtain in North America.

Silver steel has been around for a long time, and I would be surprised if it were generally any alloy steel other than plain carbon.

Been wrong before, though. :-)

British Silver Steel from Stubs has the following composition:

Min Max Carbon 1.10% 1.20% Silicon 0.10% 0.25% Chromium 0.40% 0.50% Sulphur 0.035% Manganese 0.30% 0.40% Phosphorus 0.035%

Peter

Note that those apparent minimum values for sulphur and phosphorus are, in fact, maximums :-)

Cool!

Chalk up anothe one wrong, and another thing learned.

Way more carbon than most plain carbon stock that is available.

I suppose I could look up the nearest AISI grade if I had to, but... I have a pretty good stock of drill rod, and it's working for me. :-)
