Stainless Steel Hexagon Bolts Process Introduction

The manufacturing process of stainless steel hexagon bolts is as follows: Normalizing: the screw is heated to the appropriate temperature above the critical point AC3 or ACM for a certain time and then cooled in air to obtain pearlite structure. Annealing: the hypoeutectoid screw is heated to 20-40 ℃ above AC3 and cooled slowly in [...]
