A new building pin was forged by using different initial temperatures, finish forging temperatures and forging deformations. The tensile properties were tested and analyzed. The results show that under test process, with initial forging temperature increasing from 1200 ℃ to 1280 ℃, finish forging temperature increasing from 680 ℃ to 760 ℃ and forging deformation increasing from 680 ℃ to 760 ℃, the tensile strength of the building pins firstly increases and then decreases. The optimized process parameters of the pin are initial forging temperature of 1260℃, finish forging temperature of 720℃, forging deformation of 10%.
