One man's junk is anothers treasure.
Some can run a $30 chain and be fine. Get good life out of it too.
Others can run a $100 chain and still consider it junk. They are the ones who have a hard time figuring things out.
Tensile strength is really a non-issue. As are other things that chain mfg's use to market their products. See..folks are cluless on what really makes for chain and sprocket longevity, so in an effort to baffle you with BS, they throw advances in metalurgy at you in hopes that you will be searching for the maintenance free answer to their prayers. Many fish bite.
One of the best examples of this is tensile strength. I see that levert says he would look toward tensile strength, elongation properties, hardness and machineability.
Machinability isn't much of an issue today. Even less of an issue is tensile strength and elongation. Hardness would be the only factor that would give you any advance.
You see many chains with tensile strengths of 8-10,0000 lbs. This is overkill as well as being a marketing ploy. A 500cc 2-stroke will only create about 1800lbs of chain pull on a good day, why would one need a chain that has sideplates that can withstand 10,000 lbs?
The hardness of the pins and bushings coupled with protecting their friction surfaces are the keys.
