The hardness testing is a validation of heat treatment. So, first design the small diameter Pinions, Gears and Shafts per A, then choose a matching alloy in Table 1 of A for the large diameter ring gear.
Brinell Hardness Number Range to to Grade Class Tensile Strength, min psi 85 80 95 95 95 MPa Charpy V-notch 3, 3A C, D Welding technique is of fundamental importance and it is presupposed that welding procedure and inspection shall be in accordance with approved methods for the class of material used. Close this window and log in.
Brinell hardness tests shall be made on prepared areas on the forgings after machining to the sizes ordered by the purchaser and after stress relieving if stress relieving is required.
A superscript epsilon e indicates an editorial change since the last revision or reapproval.
Welding technique is of fundamental importance and it is presupposed that welding procedure and inspection shall be in accordance with approved a2991 for the class of material used.
