Drillrod question

[Suzuki4evr]

Hallo everyone

Can anyone tell me what metal properties is of drillrod or what it consists off. I live in South Africa and I can't get hold of drillrod in my are and now I want to see if I can get something similar to it.Here I can get EN8 bright,don't know if it is nearly the same.Would appreciate if someone can help me

Thank you
Michael

This site has a PDF showing the specification of various drill rod steels. You should be able to find an equivalent from this.

O1 (Oil quenched) is a common steel in the US, this is J437 specification.

You may find it described as "silver steel", as that's the more common name in the more-recent Empire - it's a hardenable carbon steel, if you can't find it under those maybe it'll be listed as "tool steel", there are various types labelled (in the USA at least) as O[number], A[number], W[number] depending on whether they're Oil, Air or Water quenched (prior to tempering, the quench will leave them "glass-hard" and brittle)

Hallo Dave

I have just checked the sit and will compare it to what is available here tomorrow.

Thanks again
Michael

here is a great cross reference for steels from all over.

 

[Billh50]

Other designations that are equivalent to AISI O1 tool steels include:

• DIN 1.2510
• B.S. BO 1
• ASTM A681
• FED QQ-T-570
• SAE J437
• SAE J438
• UNS T31501

Thank you Bill,I will check it out.
Thank you for you input.
I am glad I joined this forum.

Hi Michael,

I have bought ground silver steel rod from RS components. Go to http://za.rs-online.com/web/c/abras...eets-angles/steel-rods-bars-tubes-hexagonals/ and select "Siver steel" from the materials filter on the left. Silver steel is closer to W-1 steel than to O-1, but I have used it to make a number of things like taps and hardened bushings.
I concede that buying tool steel from RS components is like buying toothpaste at WoolWorths, if I am allowed a local analogy , but it is convenient, and reasonably priced in smaller diameters.

I can also recommend Bohler Uddeholm http://www.bohler-uddeholm.co.za/115.php. They do sell directly to the public (I bought some O-1 ground plate from them in small quantities), just email them and ask if they can supply you with K460 ground rod. The K460 designation is their product code for an O-1 tool steel.

A last option would be http://specialsteels.co.za/; I am not sure if they stock O-1 or W-1, but when I order EN19 from a local steel supplier then they appear to order it from Special Steels. EN19 is not really a replacement for O-1 or W-1, but I love working with it. Just for completeness: EN19 is somewhere between 4130 and 4140 alloy steel, so it can be hardened, and it machines beautifully -- I much rather use EN19 than mild steel just because it turns so well with carbide tooling (unlike mild steel).

Hope this helps.
