Characteristics of Workhardening and Recrystallization of H08Mn2SiA steel

This paper introduces the characteristics Of workhardening and recrystallization of 0.08C 2Mn 1Si steel that widely used to CO₂ welding. In order to impress the changes of the characteristics of workhardening and the recrystallization of H08Mn2SiA steel, a regress method was adopted in experiment. The H08Mn2SiA steel has good characteristics of workhardening.The best temperature for the industrial technology of recrystallization is from 640℃ to 660℃.In order to shorten the time, it is possible for recrystallization temperature to heat steel ill 700℃ or higher temperature.
