Material Specification
(OP)
Can anyone recommend a steel with the following properties:
1) Must be available in solid billet form up to approx 175mm to allow deep hole boring operation to take place.
2) Material must be weldable, preferrably using the MIG / MAG or TIG processes.
3) Must be heat treatable to achieve a Rp0.2 > 680N/mm².
Thanks

RE: Material Specification
Your laundry list of needs is too general for selection of a suitable material. You need to further itemize this list by application of the component in service; reviewing service temperature ranges, corrosion environment concerns, and additional minimum mechanical properties (ultimate tensile, yield strength and ductility). Also, is the component being used in an application that requires high reliability or exposure to personnel safety?
Fabrication welding needs to be carefully considered because it is highly probable that post weld heat treatment or even re-heat treatment after fabrication will be necessary to assure minimum mechanical properties. High stregnth low alloy steels demand careful attention during welding fabrication.
So, take a moment and itemize your list to cover as much information as possible.

Thanks for your reply's. Here is the additional information as requested:
1) Wall thickness after deep hole bore 10 - 25mm
2) Base thickness up to 45mm
3) No concerns over service temperature ranges
4) Corrosion resistance - Components are plated, specification dependant on location & application.
5) Ultimate value - No design calculations are based on UTS
6) % Elongation >10%
7) For welding purposes a material with a CEV value <0.6 would be required
We currently use a material - Grade 600:BS 6258, 0.22%C, 1.5% Mn 0.08 - 0.12% V) which is readily weldable after Q&T to achieve Re >750 N/mm2. My only problem with this material is that it only comes in cylinder form and not billet.
Thanks for your assistance

That grade would be called 15V22 according to ASTM A 29 or 19MnVS6 according to EN 100267. Neither of these would be laying on the shelf of a steel service center/stockist, but they are certainly produced in large diameter bars. I am sure that Corus can/does produce this.

Billet is in solid bar form, cylinder allready has a bore
