while anealing mild steel wire maximum size 0.90mm how can we get the material without any scale formation?

Answer 1

Control your oven atmosphere.

The scale is caused by the migration of carbon from the steel to the surface, combined with the formation of other oxides, etc.

You can carbon-pack your wires or use inert gas in your oven.

It is cheaper to de-scale after annealing (generally) than it is to do this.

Answer 2

those to come back to ideas quickly are: Ray Schalk - Dude confirmed he had integrity by employing attesting against his teammates on the Black Sox...yet i do no longer think of a corridor bypass is the ideal suited reward. Reggie Jackson - great, definite...yet between the ideal? no longer so confident. i think of he could have mandatory the veterans vote had he no longer performed for the Yanks...563HR is the only style that stands proud on his line...Frank Robinson, as an occasion, had a hundred extra RBI, replaced into 30+ factors greater in AVG and extremely practically 50 factors greater in SLG. Phil Niekro, Gaylord Perry and Don Sutton - Sutton replaced right into a well-known of mine transforming into up, yet like Reggie i think of those men have been given in merely by using fact they hit between the "magic numbers" (3 hundred+ wins). i'm confident there are a collection of "previous timers" which could settle for the boot too, yet Schalk is the only one which stands out in my ideas.
