Also known as chrome-moly steel, this versatile 4140 alloy steel is used for a wide range of parts, such as gears, axles, shafts, collets, and die holders. It resists fracturing from repeated stress.

SA/A335 Seamless Ferritic Alloy-Steel Pipe for High Temperature Service in Grades P5, P9, P11, P22 and P91 are stocked in sizes 1/2" to 48", wall thicknesses up to 4". Due to the custom nature of many chrome moly projects we have developed expertise in providing special order minimum walls and ID controlled pipe to fulfill the most demanding ...

4130 chromoly round seamless tubing is highly versatile and used for a wide range of applications including automotive, aerospace, bicycling, construction, and firearm projects. 4130 tubing offers good strength, weldability, impact and abrasion resistance while also being easy to machine.

Adding chromium to steel improves strength and corrosion resistance, and the molybdenum increases material toughness. 4130 steel chromoly tubing also provides a smooth interior and exterior finish that resists scaling and oxidation.

We carry a large inventory of hard to find Chrome Moly tubing commonly used in race car construction. Price is per foot with a minimum order of 1 ft. Special orders are welcome. Call for assistance with any tubing not listed.

TW’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, TW Metals delivers a full range of rounds, squares, rectangles, and streamline products.

Alloyed with chromium and molybdenum, chromoly tubing offers an excellent strength-to-weight ratio. It is considerably stronger and harder than standard 1020 steel. Common applications for round chromoly tubing include roll cages, pressurized gas systems, bicycle frames, firearm parts and aerospace components.

Chrome moly is used in power plants, refineries, and boiler manufacturers for steam applications. As suppliers of seamless and welded alloy steel pipe, Federal Steel specializes in ‘chrome-moly’ SA335 piping in grades: P5, P9, P11, P22, and P91.

4130 tubing has an incredible strength-to-weight ratio, more durable and harder than standard 1026 tubing. It has has a relatively low carbon content, so it welds and machines almost as easily as 1018 carbon steel tubing.

4130 chromoly (chromium-molybdenum steel) round tubing is an excellent candidate for most processing techniques. This material is seamless with a smooth interior and exterior, high strength-to-weight-ratio, and is resistant to oxidation and scaling.
