Want feedback on Wear Resistant Roller Material - Thinking AISI D2
(OP)
Thank you for reading my post
I'm working on a replacement design of a weld coupon bender. This bender would bend maybe 30 coupons a month. A plunger comes down and pushes the coupon through two rollers.
I'm thinking of using shaft of 4140 (~0.84375" OD) x ~5" long that the rollers would spin on (rollers: AISI D2, ~1.5" OD x 0.875" ID x 3.625" long).
I'm concerned that the D2 material will be very brittle and may crack under the bending stresses. I'm also concerned about heat treating this part after machining because of it tube shape.
Is D2 a poor choice? If so, what would be a better choice of material that had at least moderate wear resistance?
Thanks in advance
