Hey guys this is a type of silver steel I get local and I'm wondering what we'll known steel is it like
I've been treating it like w1 but it's not I know
Carbon 1.13
Sil .22
Many .37
Phosphorus .014
Sil .018
Chro .43
Any help would be appreciated thank you
 
I’m not sure what the designation is, I’ve seen similar grades coming out of Europe. I purchased some strip steel similar to this from here in the US several years ago. This class of steel is used in the printing and paper industries.

Good steel for knives, the extra chrome will make it deeper hardening and help refine the grain. Try hardening from 1475f and temper at 400f.

With that much carbon, I’d even try running it at 1440-1460f. Do some test coupons and dial in your optimum hardening temp.

Thanks hoss and Willie
So would canola be fast enough?

The chromium will help, but it’s quite low manganese. You would be better with fast oil, but heated canola might work. You might lose 1-2 Rc points compared to fast oil.

Try a coupon in brine, and a coupon in heated canola oil and have them hardness tested pre temper. If you lose more than 1-2 points, get the right oil, or get a deeper hardening steel until you do. You can also do brinefor 3 seconds, then into heated canolato finish the quench. You will still crack the odd blade, but not nearly as many as a full brine quench.
 
Thanks Willie.
Yes that's exactly what happened it seemed to me
Quenched in canola it hardened but knew I was losing a bit
Interupted quench in brine and oil did the job better it seemed.quick 1-2 and out.didnt get them tested tho
Just wanted to check that I was on the right track
Thanks again willie
 
New in all sizes of round in my local engineering suppliers in Dublin
They always have it in stock
 
Looks like a high carbon W1 tool steel with slightly elevated Chromium %. "Drill rod". Agreed with the above posts. Keep the hardening temp 1450f-1475f, quench in fast oil.
 
Thanks for all replies guys
That should be helpful to lots of people this part of the globe as it's all we seem to have.that and o1

It’s pretty much like 1.2442 steel, a steel that Achim Wirtz sells. Drop him an email, he’s a pretty nice guy and doesn’t take too long to answer.
 
Thanks for info. If that's his super clean stuff I've read great things and remember reading about its heat trestreat somewhere too I can root it out

Not really. 1.2442 has quite a bit of tungsten in it for wear resistance, this steel does not have any tungsten or any real carbide forming alloys, other than the very small Cr addition which will help add toughness, but not wear resistance.

Think of it this way, the alloy the OP listed is akin to a deeper hardening White 2. Achim's 1.2442 is akin to Blue 2 or even Blue 1.

115CrV3 is a very close comparison, although I don't see any vanadium listed in his specs, but it could be there.

And to help clear up a few mistakes from the original post, I think this is what was meant:

Carbon: 1.13
Manganese: .37
Silicon: .22
Chromium: .43
Sulfur: .018
Phosphorous: .014
