ASTM A691 GR CMSH-70

ASTM A691 GR CMSH-70 pipes boast a carbon-manganese-silicon alloy steel composition, offering superior mechanical properties like enhanced tensile strength, excellent corrosion resistance, and high-temperature endurance. The normalizing process at 1700°F (925°C) ensures uniform microstructure and optimal performance. Available in seamless configurations from ½” NB to 36″ NB and EFW sizes up to 60″ NB, they cater to a wide range of industrial needs. The flexibility in end types—beveled, plain, or threaded—further adds to their adaptability.

The pipes’ advanced chemical and mechanical specifications make them ideal for transporting fluids in refineries, supporting marine structures, and serving as pressure vessels in power plants. The material exhibits a tensile strength of 485-620 MPa, yield strength exceeding 310 MPa, and elongation up to 22%. Additionally, their chemical composition, including a carbon content of 0.05-0.15% and manganese range of 0.90-1.20%, ensures durability and resistance to wear and tear in demanding environments.
ASTM A691 GR CMSH-70 pipes are available in various configurations, including seamless, welded, and EFW options. With wall thicknesses ranging from 2 mm to 60 mm and schedules spanning SCH 10 to XXS, they can handle both low-pressure and high-stress applications. Their versatility is further enhanced by customizations in length, thickness, and finishes, making them suitable for diverse industrial applications.
