Working on a lock that goes on a trade pistol made by Curly Gostomski. Anybody know what steel he used for the main spring? It is a cast spring. Had to spread the arms a tad for more power. Now need to re-heat treat.
I don't know what steel he used, but most steels will harden when heated to the point a magnet won't stick then oil quenched. Tempering temp is more specific to the steel. For springs I like to use the melted lead method . :idunno:
I have no idea what he uses but I harden and temper at the same temps no matter what steel is in the spring. If that doesn't work then he used a inferior steel and the spring needs to be replaced.
1550Â° to harden. 725 to 750 for 20 minutes to temper. always works.
