AISI 4140 Tube

SAE 4140 Seamless Pipe and ASTM A519 Grade 4140 Steel Tube Supplier in India.

Alloy AISI 4140 are low alloy elements that are economical in comparison to stainless steel. The AISI 4140 Tube is produced with a chemical composition of carbon, manganese, potassium, sulfur, silicon, chromium, and molybdenum. These tubes are designed to suffice in medium to high corrosion-induced environments. This 4140 Chrome Moly Tubing exibits resistance to crevice corrosion and cracking due to acids. They can be easily machined and fabricated to form desired elements. The 4140 Alloy Steel Tube has high ductility and can be easily annealed or galvanized. These tubes can be readily produced either by the cold or hot-rolling process. They are available in lengths up to 13500 mm. An AISI 4140 pipe exhibits superior strength and mechanical properties. These pipes possess a minimum tensile strength of 655Mpa and a minimum yield strength of 415Mpa. We follow all the standard processes and tests followed by all AISI 4140 Tube Suppliers while producing the best products.

SAE 4140 Pipe

ASTM A519 Grade 4140 Round Tube

SAE 4140 Pipe offers excellent fatigue resistance along with good wear resistance in different stress-induced environments. These pipes can be pickled to give them enhanced protection against various elements. The SAE 4140 Alloy Steel pipe exhibits exceptional torsion strength and enhanced hardness. These pipes are available in sizes ranging between 1/2NB to 24NB. An SAE 4140 Seamless Pipe exhibits superior strength as they are produced with a single piece of sheet metal. These pipes are highly reliable, and function well in high-pressure and temperature systems. The ASTM A519 Grade 4140 Welded Pipe is made with the help of welds and seams. These pipes are a cost-effective alternative to a seamless pipe. They are available with a wall thickness between 3mm to 12mm. The UNS G41400 Alloy Steel Tube is highly versatile and can be availed in plain, beveled, and threaded ends.
