Normally my company machines small NPS (1/8" & 1/4") ASME B16.11 stainless (304,316) hex head plugs directly from small diameter bar, at great tooling and machine expense.
I am exploring the idea of cold forming/heading OR hot-forged hex head plugs with rolled threads. A couple hurdles arise in...
Hello,
A customer is asking for "forged bar" as the starting material for a certain finished part. We have in stock what the mill refers to as "rolled bar", which the customer will not accept. I can't seem to find a definitive difference between "forged" and "rolled" bar. Depending on where you...
Hi everyone,
Is it possible to anneal piping products that have already been final machined? Specifically it is F304/L.
The bar we made the parts from were orginally Normalized and Air Cooled. I need them to be Water Quenched.
Can this be done without ruining the dimensions of the parts or...
Hi everyone,
I have another similar problem with the notorious F53 Duplex SS. I had 3" OD forgings of different shapes. They were processed as follows:
Close Die Hammer Forged @ ~2235-2250 F, then water quenched.
Annealed @ ~2015 F for 2 hours, then water quenched.
Two of the shapes passed...
Hi everyone,
I have a problem regarding F53 duplex SS. We were annealing 2-1/2" OD forgings in-house at the recommended ~2000 deg F. The forgings were taken out even before any quenching with long cracks along the surface or even split in half. I know that the intermetallic sigma phase can cause...
