I believe W means wrought, and it appears that Y refers to yield strength, with the number indicating the minimum specified YS, i.e. Y 52 would indicate a minimum yield strength of 52 ksi. But let me verify this.

A860 is the ASTM standard.

ASTM A860 / A860M - 08 Standard Specification for Wrought High-Strength Low-Alloy Steel Butt-Welding Fittings

Abstract

This specification covers wrought high-strength low-alloy butt-welding steel fittings of seamless and electric fusion-welded construction for applications in high-pressure gas and oil transmission and distribution systems. Starting materials shall consist of plate, sheet, forgings, forging quality bar, and seamless or fusion-welded tubular products with filler metal added. Materials shall be heat treated by normalizing, quenching, and tempering or stress relieving. Specimens shall conform to required values of chemical composition and mechanical properties, namely: yield strength, tensile strength, elongation, notch toughness, and hardness. This specification does not require hydrostatic testing.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.


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, ASME B16.28, 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 A 960/A 960M. These fittings are for use in high-pressure gas and oil transmission and distribution systems.

1.2 Optional supplementary requirements are provided for fittings when a greater degree of examination is desired. One or more of the supplementary requirements may be specified in the order.

1.3 This specification does not cover cast-welding fittings or fittings machined from castings.

1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification. Unless the order specifies the applicable M specification designation (SI units), the material shall be furnished to inch-pound units.

Thanks for the reply.

I agree A 860 is ASTM Standard and Y 52 Stands for yeild strength.

But this material is suitable for API 5L GR. B Sour service piping or I have to go for API 5L GR X 52? What is the difference between these 2 piping matyerials? A234 Gr. WPB Sour Service. What is the property of this material?
