DM Special Steel Ltd’s cold drawn seamless chromoly 4130 tubing is a lighter weight, higher strength alternative to carbon steel. As the market leader in seamless 4130 tubing, DM Special Steel Ltd delivers a full range of rounds, squares, rectangles, and streamline products. Our tubing is manufactured to Mil-T-6736B, AMS-T-6736, ASTM A519, and AMS 6360 specifications.
4130 Alloy Tubing is commonly referred to as Chromoly, which contains chromium and molybdenum as alloying elements. Chromoly is superior to mild carbon steel based on a strength to weight ratio, making it widely used in applications that require less weight but similar strength. Such as roll cages for race cars, high performance bicycle frames, and fuselages for aircrafts.
4140 Alloy Tubing is a low alloy steel, with the addition of chromium, molybdenum and manganese as alloying elements, combined with heat treatment, gives 4140 alloy the advantage of hardness, ductility, and strength. Commonly used in applications for Oil and Gas, Agricultural equipment, and heavy machinery components.
Benefits of Round 4130/4140 Alloy Seamless Mechanical Tubing
Alloy Steel 4140, also sold under the name AISI/SAE 4140, is a low alloy steel that contains chromium, molybdenum, and manganese. Known for its impact and abrasion resistance, Alloy Steel 4140 also offers users outstanding fatigue and torsional strength. Welding is possible through most popular techniques, and it has a high level of ductility. Machinability is possible in the annealed condition, while Alloy Steel 4140 takes cold working, heating, and quenching well.
To be considered Alloy Steel 4140, a product must contain a certain chemical composition that includes:
Due to its toughness and other positive characteristics, Alloy Steel 4140 is found in a wide variety of applications such as:
