Metinox Overseas supplies high-yield wrought carbon steel WPHY 60 butt-weld pipe fittings certified to ASTM A860 / ASME SA860. Engineered for extreme-pressure oil & gas pipelines, available in sizes 1/2″ to 48″ NB with same-day quotation response.
Request QuotationASTM A860 WPHY 60 pipe fittings are considered as the standard in wrought high strength, low alloy ferritic steel butt-welding fittings for seamless and electric-fusion-welded construction. The "WPHY" designation dates back to the early 1960s when the steel was produced as high-strength specialty products to meet the need for materials with very high yield strength that were superior to standard-grade carbon steel fittings.
These fittings are especially designed for applications where strength and integrity of the pipeline are paramount requirements in gas and oil transmission and distribution lines. WPHY 60 is used in a variety of industries including petrochemicals, power generation, offshore platforms, and LNG facilities because of its excellent toughness, notch resistance and resistance to hydrogen induced cracking.
Metinox Overseas is a manufacturer and exporter of a wide variety of ASTM A860 WPHY 60 pipe fittings that fully meet ASME B16.9, ASME B16.28 and MSS-SP-43 dimensional requirements, such as elbows, tees, reducers, end caps, stub ends, crosses, and bends.

ASTM A860 WPHY 60 fittings offer measurable performance advantages over standard carbon steel grades.
With a minimum yield of 415 MPa (60 ksi), WPHY 60 fittings withstand operating pressures far beyond what standard WPB (A234) or ASTM A53 piping can handle, reducing wall thickness requirements and total installed weight.
Heat treatment via normalizing, quenching, and tempering improves the material's impact toughness. Charpy impact tests at −50°F (−45°C) confirm suitability for cold-climate and cryogenic-adjacent service.
Completely killed fine-grained steel microstructure provides good resistance to hydrogen-induced cracking (HIC) and sulfide stress corrosion cracking (SSCC) — critical for sour-service environments per NACE MR-01-75.
WPHY 60 material is formulated for superior field weldability. Low carbon content and controlled carbon equivalence (CE ≤ 0.42%) minimize preheat requirements and reduce risk of hydrogen cracking in weld heat-affected zones.
Higher yield strength allows use of thinner walls for the same operating pressure, reducing material costs, weight per meter, and installation complexity — offering TCO advantages over both stainless steel and thick-wall carbon steel alternatives.
Each fitting is accompanied by Mill Test Certificates (MTC) per EN 10204 / 3.1B, Positive Material Identification (PMI), and radiographic inspection reports — ensuring complete traceability from raw material to dispatch.
ASTM A860 WPHY 60 pipe fittings are specified by engineers across the most demanding sectors worldwide.
