I want to manufacture ASTM 860 GR W I want to manufacture ASTM 860 GR W Arkaprava Ghosh (Mechanical) (OP) 20 Mar 17 06:06 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 metengr (Materials) 20 Mar 17 12:09 Look at the API 5L X60 Pipe Grade. RE: I want to manufacture ASTM 860 GR W WKTaylor (Aeronautics) 20 Mar 17 13:15 Arkaprava Ghosh Per ASTM A860 Wrought High-Strength Ferritic Steel Butt-Welding Fittings, Standard Specification ... 1. Scope* 1.1 This specification covers wrought high-strength ferritic steel butt-welding fittings of seamless and electric fusion- welded construction covered by the latest revisions of ASME B16.9 and MSS-SP-75. Butt-welding fittings differing from these ASME and MSS standards shall be furnished in accordance with Supplementary Requirement S58 of Specification A960/A960M. These fittings are for use in high-pressure gas and oil transmission and distribution systems.

["Orion", Homebuiltairplanes.com forum] RE: I want to manufacture ASTM 860 GR W metengr (Materials) 20 Mar 17 19:47 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 SJones (Petroleum) 21 Mar 17 03:33 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.

RE: I want to manufacture ASTM 860 GR W metengr (Materials) 22 Mar 17 17:26 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 Arkaprava Ghosh (Mechanical) (OP) 23 Mar 17 05:43 Thankyou all. API 5l Gr X60 seems to be the best option.
