AISI 4340 Tube

SAE 4340 Seamless Pipe and ASTM A519 Gr 4340 Steel Tube Supplier in India.

Alloy AISI 4340 is made from low alloy elements which possess good strength. The AISI 4340 Tube is made with a high chemical composition of nickel, chromium, and molybdenum. This makes these tubes highly resistant to corrosion and oxidation in different environments. The 4340 Chromoly Tubing enables it to exist in high-pressures and elevated temperature systems. This tubing can be formed by standard hot-rolling or cold-rolling procedures. The AISI 4340 Alloy Steel Tube exhibits exceptional strength and excellent mechanical properties. These tubes have a minimum tensile strength of 1014Mpa and a minimum yield strength of 835Mpa. The AISI 4340 Steel Pipe can be easily machined and fabricated. These pipes can be easily elongated by 13% and still exhibit excellent workability. They possess a hardness between 248 to 444 Brinell. We follow the standard processes and tests followed by the leading AISI 4340 Tube Suppliers.

AISI 4340 Tube

SAE 4340 Pipe

ASTM A519 Gr 4340 Steel Tube

The SAE 4340 Pipe is designed with excellent shock and wear resistance. These pipes offer good ductility and excellent reliability. They can be hardened or annealed on request. An SAE 4340 Seamless Pipe is designed without the requirement of welds or seams. The single sheet pipe possesses exceptional strength and enhanced performance. They are a little expensive due to the materials used in their production. A519 Gr 4340 Steel Tube is a high-performance tube that exhibits exceptional strength. These pipes exhibit a sturdy construction with an excellent finish. They have a long service life in stress-induced environments. ASTM A519 Grade 4340 Tube can be availed in single random, double random, and custom sizes.
