ASTM A194 GR.8 fasteners consist mainly of medium carbon steel, usually alloyed with manganese, chromium, and molybdenum for increased strength and hardness. The fasteners are heat-treated to possess a tensile strength of around 120 ksi (827 MPa) and a minimum yield strength of 92 ksi (634 MPa). They possess very good mechanical properties, such as high tensile strength, hardness, and wear and fatigue resistance, and are appropriate for use in high-pressure and high-temperature services.

ASTM A194 GR.8 fasteners find extensive application in high-stake industrial applications like oil and gas, petrochemical refineries, and pressure vessels. They are used for applications of bolting where strength and corrosion resistance are critical, such as flange assemblies, valve assembly, and heavy-duty machinery. The fact that they can handle tough conditions makes them unavoidable in settings subject to extreme pressure and temperature, making it possible to ensure safety and reliability of critical structural and mechanical joints.
We provide our customers with complete documentation to ensure the highest standards in manufacturing and supply. This includes fuming certificates under EN 10204/3.1B, marketing documents, heat treatment plans, quality control systems, packaging materials, material certificates, MTCs and more. We provide 100% radiography test reports and other relevant certifications.
