High-Pressure Threaded Fittings

Threaded fittings belong to the “high-pressure fittings” group. They are available in all inch sizes. Each fitting is stamped with size, grade, melt number, and pressure class. They guarantee safety and durability of installations. All threaded fittings come with 3.1 certificates.

A105 Steel Properties

A105 is a carbon steel commonly used in pipelines, flanges, and fittings. This carbon steel grade is suitable for ambient and elevated temperatures, as well as for use in pressure installations. It has good machinability, typical of low-alloy steel, and is weldable.

Applications: refineries, metallurgy, marine industry, high-pressure installations, high-demand systems, high-temperature A105, low-temperature LF2, boilers, pressure vessels, hydraulic systems, outdoor installations, oil and gas industry.

This grade is commonly used for oil and gas transport, petrochemical plants, power stations, and similar high-demand applications.

Comparable Steel Grades: 1.0460, C22.8, P245GH, P265GH
