Looking for a Low Temperature alloy steel tubing
Looking for a Low Temperature alloy steel tubing
(OP)
I am looking for a seamless steel tubing specification to replace ASTM A106 gr. C in a very low temperature application for a hydraulic cylinder.
The minimum yield must be similar to A106C and it needs to meet the charpy v-notch test requirements per ASTM A370, 31 ft-lbs average at -50C.
The OD is in the range of 3-4" and the finished ID is 2.0-2.5". (Several applications with various ID/ODs) Hopefully I can find something that is not too exotic or hard to find in North America.
Any help anyone can offer would be greatly appreciated.

Agreed. I would also consider ASME SA 333 Grade 9 seamless pipe material. The minimum yield strength is 46 ksi. Minimum Charpy impact test is -75 deg C, so it might get 31 ft-lbs at -50 deg C.

Does anyone know what kind of charpy values I could expect from A-192. I know the yield is lower but I may have to adjust the wall thickness if I can't get a 40KSI material to pass charpys.
