Thread: Steel specifications

How deep do you want to go? I'm clueless but here's a couple of things that might help.

Every country has a code for each grade of steel where in Australia, AS250 is mild steel (bog standard). Each different grade indicates the different properties used for the grade. This is a good guide:

Basically, the higher the carbon content, the harder (and more brittle) the steel is. From here you should be able to search each different grade of steel and determine what applications can be used for each.

Then you have alloy steels...

Hi,
The biggest problem i have encountered is that the Americans call the same steel a different grade to here in Oz. I have some good info in books but these are still packed in boxes from when we moved house 3 years ago.

Was there a particular use that you wanted to know about?

Also, once you have worked out what you want getting the stuff here can be hard.

Most bearing shops should sell "silver steel" here is a bit of the wiki doc: The composition is defined by UK specification BS-1407, and is as follows: carbon 0.95–1.25, manganese 0.25–0.45, chromium 0.35–0.45, silicon 0.40 max.[1] In the annealed state is has a hardness of 27 HRC. It can be hardened to 64 HRC
I think it has a few different names, but without a book i'm a bit stumped, although alva 14 rings a bell. It is pretty useful for general work. For something a bit more tougher 5160 is good as a spring steel, it also contains chrome so it is a bit more rust resistant. 4140, chrome-moly is even tougher, good for making hammers from....
I'll try to fish out some books, but they will all be american so some translation is required. Although i think i may have a bit of paper with some notes in one......

Have a scratch around on the Bohler Uddeholm site in the products section. You will see the various steels listed down the left side, select those and you will find downloadable .pdf files. Their medium tensile carbon steels are listed in with the mild steels.

Mild, medium tensile and free machining low tensile.
Bohler-Uddeholm Australia - Bright Mild Steel The download pdf is at the bottom.

High tensile alloy steels
Bohler-Uddeholm Australia - High Tensile Individual pdf's for each grade.

The other steels and non ferrous are there on the left side of the page.

Different suppliers know these grades, the grades are well known in Australia. Bohler Uddeholm have branches around Aus. though you may not be able to buy small quantities from them.

Cheers.

If I'm not right, then I'm wrong, I'll just go bend some more bananas.

Another supplier that has some info on site is

Interlloy | Alloy Steels and Special Metals Look under Products.
