I have wire cut a 40 mm 12 tooth , 0.5 mm lamination thickness stator piece , there are 16 pieces
Im doing a skip tooth Classic LRK wind
large prop at about 4000 RPM
Do I need to anneal the stator pieces after wire cutting
Does wire cutting greatly effect the properties of the steel or...
How do you remove that dark oxide layer on SS
Portions of my parts are very narrow with small holes 3mm and I cannot quite get the TIG brush in the area Also ,,,
Tig brush creates heat which can warp slender parts
Can you recommend some powerful pickling ????
Thank You
Its 10 Al 68 Copper and 4% iron
Turned out more Magnetic than 316
So Can it be removed by electric means
I dont want to heat very high as they are longish bars
Thank You
Colleague, has a SS tube 30 Dia by 400 long with an oil seal type running on the 30 dia
Slowly
Usually wet
But can turn dry
Approx 10% salt water
Looks like a galvanic type corrosion at the seal area
No heat involved
Can you recommend a metal , SS ? I dont think plastic will do...
I need a pill 2mm Dia by 1 thick with a 1 hole thru , pure
I have manganese powder
can it be vacuum melted in say a 3mm pyrex tube , then machined to size
I hear its hard and brittle , what Rc would that be
Thanks
In Astropysics equip there is a tendancy to use SS for bearing elements
No rust
I worry that some parts I make such as a bearing elements from 316, at dimensions 120
x 60 by 12 thick out of bright bar
What is your estimate of stability over time with out heat treat
Good afternoon
I am tempering 431 in the range that adversly effects corrosion resistance
I suppose its the chrome thats depleted
Final hardness is 42 Rc
My part runs at 40,000 PSI in pure water
Would pressure also deplete corrossion resistance
Good Morning
I have to screwcut , some 30mm Dia bars of this Matl used as a pressure vessel , 40,000 PSI / 800C
Can I get an idea of the machining characteristics
Thank you
Have got a room size vacuum system with inside parts that need accurate alignment relative to one another
Height wise too
Is there a large laser or similar system that will resolve about 10 thou in 3D
The aero people must have this down pat with their big structures
Thanks
Can any of you fine men tell me where I can get info on fitting these bearings
For Eg a 10 mm OD bearing , What size hole is it' a 10mm reamed hole or a reamer that cuts 1 thou under size
I want to get it right so the bearing works correctly
Many Thanks

Im machining a V block from 316 SS ,,,,,450 long by 70 mm square
And it has to stay dimensionally stable within 1 thou over about 20 years
Im doing it out of bar stock
If I just rough and machine it without any heattreatment would it be OK
And also can you recommend a heattreatment to...
Im looking for the oil or additive that helps 2 stroke GP 125CC engines survive at the end of the sraight when the throttle is closed
There is one
