Any info or reference about ultra high strength cast steels please
(OP)
I am scheduled for an interview with a company manufacturing wear products for mining and construction industry. They are looking for development of parts in ultra high strength cast steel. I shall appreciate,if any of the members have any inputs to provide.

In these instances, the greatest wear resistance has come from using mixtures of metal powders which contain higher amounts of VC than can be cast. (Crucible)I suspect there's a clever way to do this with individual castings.
I would tell your prospective employer that you have the entire Eng-Tips team on your side and he would be foolish to not hire you.
Good luck!

The alloy is martensitic, with Ni3Ti-type 'eta' precipitation strengthening. To avoid formation of Al, and Ti oxides during solidification, the alloy is best suited for vacuum investment casting. Beyond about 4-5" section thickness the properties start degrading.

Dear Friend
Anyway if they don't hire you. They have lost a HUGE Metallurgical experience.
For me : you are a GREAT Metallurgist
Respect !
Ps : ultra high strength steels is dedicated mainly to Aerospace grades : ATI, Carpenter,Aubert & Duval, Tata Steels(Former Corus, QuesTek........
I never hear about applications of these steels grades to Mining Market.

Just came across your post. You hardly ask any questions, you're the dude always with the answers. Anyway, if I can add my 2 cents, though it's probably to late. We cast dozens of parts for mining industries from a few lb to 1000lb, mostly in 4340 and some in 4140. We supply castings in normalized condition for the customer, they quench the parts, and temper I believe at 400F, so in case 4340 you end up with over 500BHN, TS 250ksi, YS 230ksi min. Popular, "cheap" alloy that proved itself in service for long time now. Occasionally we cast train wheels in this alloy (not much demand lately).And since we on the subject, they order some parts in abrasion resistant iron, mostly 532 class 2 type B grade.

I have been associated with one company to develop markets in India and this relation has come to an end due to shift in business priorities.
