SA334 Grade 6 Seamless Tube Description
SA334 Gr.6 is a seamless alloy steel tube manufactured according to the ASTM A334 standard, which covers seamless and welded alloy steel tubes intended for low temperature service.
Material and Composition:
Made of alloy steel with controlled chemical composition for enhanced strength and toughness.
The grade 6 designation refers to a specific chemical composition and mechanical property requirement under ASTM A334.
Key Features:
Seamless Construction: Manufactured without welding seams, providing superior strength, integrity, and resistance to pressure.
Low Temperature Service: Designed to maintain mechanical properties and toughness at low temperatures, making it suitable for cryogenic and sub-zero applications.
High Strength and Durability: Alloying elements improve mechanical properties such as tensile strength, yield strength, and elongation.
Corrosion Resistance: Offers moderate resistance to corrosion depending on the exact chemical composition and operating environment.
Common Applications:
Pressure vessels
Heat exchangers
Boilers and boiler tubes
Chemical processing plants
Low-temperature service equipment
Petrochemical and oil & gas industry piping
Typical Mechanical Properties:
Tensile strength: Usually above 415 MPa (can vary depending on exact manufacturing)
Yield strength: Around 240 MPa (may vary)
Good elongation and impact toughness at low temperatures
Manufacturing Process:
Cold or hot seamless tube produced by extrusion or rotary piercing.
Heat treated and tested according to ASTM standards to ensure compliance.
