At which temperature does 0.90 mm ms wire coil get full and bright annealing . please brief me on it.? - full annealing time
Full annealing: Carbon steel is approximately 40 ° C above the AC3 or Ac1 for 1 hours, all of which ensures heat is transformed into ferrite austenite (although cementite might still exist if the carbon content above the eutectic). The steel must be cooled slowly in the range of 38 ° C (100 ° F) per hour. In general, only the furnace is cooled, when the oven is made with steel inside. The resulting structure thick perlite °, which means that the "tapes" are thick from perlite. Fully annealed steel is soft and supple, without internal tensions, it is often necessary for the formation of cost-benefit ratio. Spherical steel, softer and more supple.
Annealing: A process is used to stress in cold worked carbon steel flat products with less than 0.3 wt% C. The steel is heated to relieve usually to 550 - 650 ° C for 1 hour, but sometimes, as temperatures up to 700 ° C. Picture right shows the area occurs in the ignition.

As for the temp. I do not know, but the gold or silver thread spirits of all sizes ... I would like a cherry-red uniform. Sometimes if I have the very fine wire and small parts I am better with the light, so you can see the color. I have learned that the person is a master jeweler in the doctrine. That is, until now, 57 years in the jewelry sector, while ICH 9 clock.
