It doesn't matter what you or I think it matters what a shrud lawyer can make a group of people think and how much money he has to make them think that.... and accidents do happen... that is why we try to build in a margin of error...

I copied these definitions, and psi numbers off the internet.
Yield Strength: The maximum load at which a material exhibits a specific permanent deformation
So the 18-8 stainless will begin to deform at 80,000 psi. 80,000 psi will not cause the 18-8 stainless to fail, just bend.
Tensile Strength: The maximum load in tension (pulling apart) which a material can withstand before breaking or fracturing.
The 18-8 stainless has a tensile strength of 125,000 psi. One can see that it takes considerable more pressure to actually break 18-8 stainless when one tries to pull it apart.
One should also consider, when used as a ventliner, the 18-8 stainless is being used in compression, not tension. It seems apparent to me, that when used as a ventliner, the 18-8 stainless is considerably stronger than the 125,000 psi of tension, and as such, probably won't be the first component to fail, if one double or triple loads, or worse; a muzzle loader.

The information you supplied will show how week the metal is in comparison to the grade 8 steel that should be used. Like i have said all along. The stuff you are using is the cheapest imported Stainless steel that you can buy. And soft in comparison as well.
You supplied 1/2 the information so far. Maybe when you supply the other half you will understand. Only time will tell.

One might begin to be concerned if one of those stainless liners ever deforms enough to close of open up the flash hole. Until that happens (like never), I wouldn't worry in the least.

This statement confuses me. All the information i have available, about 18-8 steel has been provided. I don't know anything else. If you wish, we can agree that i indeed, do not understand.
