Under what conditions do you use them would be helpful. Components used for actual mountain biking will not last as long as those used for commuting, or those used in wet/sloppy conditions won't last as long as those used in dry/clean conditions. Do you ride using this ring most of the time?

The bike has only been riden on road less then 30kms off road. Its used for commuting mostly. But not all ways used in second mostly in 42 chain ring as its riden on the side of the motor way for 20kms a day.

I think its a comman problem just to light weight not enough strenght i think. Im going to try a new chain ring better spec and different chain could possibly get better life out of it.
