Effect of annealing temperature and holding time on the recrystallization behaviour and mechanical properties of hot rolled stainless steel SUS410L was investigated. Results showed that the hot rolled plate SUS410L did not complete the recrystallization process when annealing temperature was 700 ℃ and holding time was 480 min. The recrystallizai- ton completion time for annealing temperatures of 750 ℃ and 800 ℃ were 120 min and 30 min respectively

grains gradually grew bigger after the completion of recrystallization. To avoid the formation of martensite which decreases the elongation of the material

annealing temperature should not be higher than 800 ℃. Mechanical properties of the material were closely correlated with the recrystallization level. Annealing temperature of 750 ℃ and holding time of 480 min led to the best comprehensive mechanical properties: elongation of 38%

HRB hardness of 67

yield strength of 236 MPa and tensile strength of 441 MPa.
