I want to manufacture ASTM 860 GR WPHY 60 fittings. What ASTM pipe grade should be ordered as starting material?

RE: I want to manufacture ASTM 860 GR W

Look at the API 5L X60 Pipe Grade.

RE: I want to manufacture ASTM 860 GR W

If you review the referenced ASTM specification, you will find there are limited chemical composition requirements but no reference to a particular grade of material with which to manufacture the fittings. The OP actually posed a good question related to starting material to manufacture fittings.

As I stated, a good starting material is API 5L Grade X60, which meets A 860 chemical composition and strength requirements to manufacture fittings. There are others starting materials as well.

RE: I want to manufacture ASTM 860 GR W

Depends on how the material responds to the mandated heat treatment. Starting with a TMCP pipe and then heat treating it might lead to grief.

The other option you have for starting material is A 105 for fittings. You would need to procure the pipe with chemical requirements listed in A 860.

RE: I want to manufacture ASTM 860 GR W

Thankyou all. API 5l Gr X60 seems to be the best option.
