i need detailed information about annealing of 316 L which is used in stent production. If there are micrographs for different anneling temperatures i will be more pleased..

In addition i need data about the effect of different cooling speeds on the annealed 316 L
Go to the web site below and register (it is free). There is excellent information on various grades of stainless steels (properties, heat treatments) used in medical applications;

there are useful informations about 316 L, thank you. But i need specific information about annealing behaviours of 316 L. In my firm, annealing of 316 L is made about 850 C. I specifially need various cooling curves for different cooling speeds and information for waiting time at 850 C.

It depends on why you are annealing. Has the part been welded and you are trying to recover a homogenous microstructure, or are you trying to simply relieve stresses from machining?
In the first case you need higher temps and longer times. The second case you can do with shorter times at lower temps.
In good L grade material the cooling rate is not a big deal. It is easy to cool quickly from high temp,and once you are under 1200F the cooling rate can be slow, in fact you might want to cool slower to minimize distortion.

Firstly i want to thank you about the distortion-cooling speed relation information.. Our 316 L stent material comes us annealed.. we have a laser process to pattern the stent.. then we anneal the 316 L part.. there are effected zones in laser process.. we want to get back the old mechanical values of our stents affected zones (before the laser process mechanical values).. i'm new at my firm, so your informations are so important for me..

What possible HAZ damage is there? You can't have any carbide precipitation if your C levels are low enough.
How do you anneal now? How do you cool? I presume that the parts are very small and thin.
A small fludized bed system might be good for this since it would be uniform and tightly controled.
