high strength ball joint
high strength ball joint
(OP)
I need to make a ball joint as small as possible, so I need to use a high strength steel. The ball has an integral threaded shaft. The max tensile load is 60% of the max compressive load. Temperature is <200F, >-100F. Life of part is short - few high loads.
I'm looking for suggestions for candidate high strength steels.

18 NI MARAGING STEELS (SAE AMS 6512 and 6514)
AF1410 (SAE AMS 6527)
AerMet 100 (SAE AMS 6532)
AerMet 310 (SAE AMS 6478)
Custom 450® PH stainless steel (SAE AMS 5763 or AMS 5773)
Custom 455® PH stainless steel (SAE AMS 5617)
Custom 465® PH stainless steel (SAE AMS 5936)
Lower cost options would be 4340, 4335 + V, 300M, 35NCD16

Further refinement obviously depends on the details like service environment, desired manufacturing process, production quantities, etc.
