Boiler Rivet Steel supplies
« on: 14 November, 2012, 07:06:14 pm »
Hey all
I am after some correct grade steel to make some 3/4"
Does anyone know a supplier
Whoever is doing boiler rivetting must know

Regards
Marc

Australian Code of Practice for Locomotive Boilers (Version1.01 16 June 2011), the Appendix R gives the following details for rivet material.

Carbon, not more than 0.20%
Manganese, not less than 0.40%
Sulphur, not more than 0.05%
Phosphorus, not more than 0.05%
Elongation, not less than 25%
UTS, 400MPa to 460MPa
Yield strength, 50% of the tensile strength.

The appendix also offers the following comments:-

That the material be sufficiently ductile to allow the rivet head to be formed and the shank deformed to fill the hole without cracks forming in the rivet.

That many modern steels are cold worked, and although they may have the correct chemical composition, they will not comply with the mechanical properties.

All this means that the 1020 bar the steel merchant wants to sell you is almost certainly cold-worked and will not pass any of the usual mechanical tests that rivet bar should pass. This includes the 180* bend test whereby the cold rivet bar is bent hard back on itself without cracking on the outside of the bend.

l expect the same material would apply to fire box stays being threaded screwed through the inner and outer walls then riveted over each end ?

If you  ring EJ Hadaway in Melbourne they make to order, you need to speak to Scott and he will help out very good service.

Already talked to Scott about making rivets
They dont make them to the code
They will machine them up out of 1020 mild steel
the rivets must be hot formed on the first head, not machined
