Materials selection for pump shaft
(OP)
Can ASTM A582-Gr416 be used for the pump shaft at the minimum design temperature of -46 DegC?
Thanks.
Thanks.

Obviously, machinability will be strongly reduced but if you require an AISI 630 with S= 0,02-0,03% , this matter could be reduced. Soft Martensitic , as 1.4418 -very popoular in North Europe- is usually supplied with S= 0,010 -0,020%. About machinability, AISI 630 is better and cheaper (Molibdenum alloy surcharge). A lot of automotive industries machines this grade for high pressure common rail diesel system and has not problems. An other choise, it could be an Austenitic stainless steel as AISI 304 supplied in cold drawn bars in order to obtaine same mechanical properties ( Rp0,2, Rm )of 416 H+T. Kv at -45°C will be highest. In order to increase machinability, you can ask a Calcium Treated 304 grade. There is a lot of SteelMakers who produces austenitic grades by this methode,but -in my opinion- only 3 or 4 brands assures high reliability in terms of repetitivity of results about machinability.
