Product Summary
ASTM A860 WPHY42 steel tee pipe fittings are high-strength low-alloy (HSLA) materials for oil and gas pipelines, meeting MSS SP-75 standards. Defined by mechanical properties (42 ksi min yield strength) rather than fixed chemistry, they offer durability and toughness with customizable alloy compositions within specified limits.

Product Description
ASTM A860 WPHY Series Steel Tee Pipe Fittings
Product Overview

WPHY 42 is a high-strength low-alloy (HSLA) pipe fitting material designed for demanding pipeline systems, particularly in oil and gas applications. Manufactured to MSS SP-75 specifications for wrought, high-strength butt-welding fittings, these materials are engineered to meet rigorous mechanical property requirements.

Typical Chemical Composition (WPHY 42)
Element Composition Range (Weight %)
Carbon (C) Up to 0.26% max
Manganese (Mn) 0.87–1.35%
Phosphorus (P) 0.035% max
Sulfur (S) 0.035% max
Silicon (Si) 0.13–0.45%
Microalloying Elements (V, Cb/Nb, Ti) Small amounts (typically below 0.1–0.2%)
Key Technical Characteristics
  • Performance-Based Specification: WPHY 42 is defined by minimum yield strength (42 ksi / 290 MPa), tensile strength, and impact toughness requirements rather than fixed chemical composition
  • Manufacturing Flexibility: Steel producers can adjust alloying elements within allowable limits to achieve required mechanical properties
  • Variable Composition: Chemical composition may differ between manufacturers and specification revisions
Application Guidance

Critical Note: For welding procedure qualification, corrosion analysis, or material compatibility assessments, always refer to the specific heat's Mill Test Report (MTR) / Material Test Certificate (MTC). This document provides the actual measured chemical composition for your specific material batch.

Basic Material Selection: The typical composition ranges provided are sufficient for general materials selection and specification purposes.

Advanced Engineering Applications: For WPS/PQR development, FEA with temperature-dependent properties, or detailed corrosion behavior analysis, obtain exact chemistry data from the supplier's MTR and consult the latest MSS SP-75 standard along with any applicable client or company specifications.
