A131 Grade AH36 steel characteristics and uses: hardenability, heat treatment deformation, low temperature toughness, good cutting performance, but poor weldability. It can be used for carburizing parts and tempering parts with large cross section and high load, such as gears, shafts, worms, sleeves, wheels, etc.
A131 Grade AH36 steel delivery status: delivered by heat treatment (normalizing, annealing or high temperature tempering) or no heat treatment, the delivery status should be stated in the warranty book.
