Pump shaft

Thread Content

For the pump shaft, API610 specifies AISI 4140 for material S-5; however, I’ve seen some manufacturers use SS420 – I’m not sure if that is acceptable

AISI 4140 is equivalent to 42CrMo and belongs to the category of ultra-high strength steels. SS420 is the low-alloy structural steel Q420. It’s best not to substitute. Available: alloy steels with good comprehensive mechanical properties such as 40CrMOA, 35CrMo, 3Cr17Mo, etc.

Can 2Cr13 be used?

It can be used, but it is suitable for applications with low torque and low alternating loads. It has a certain degree of corrosion resistance.
