Message No. 19715, Started by rapefunda on 04/30/08

Dear Gentlemen,

We are having an annoying problem of frequent shearing of our 1045 480mm diameter shaft that crushes the sugar cane. Due to limitation of the structure, the only option left is to upgrade the mat'l. Are we on the right decision of upgrading the 1045 to 4340? Second, what is the best heat treatment, hardness and tempering range for a high torque applications?

thank you.
