Round-shape 4140 seamless tubing is medium carbon alloy grades, which are widely used for many general purpose applications that require high tensile strength and toughness. The addition of chromium and molybdenum as alloying elements, combined with heat treatment, provides the combined advantage of hardness.
140 steel tubing is a moderately simple steel with a high degree of toughness and tensile strength, it is useful for machined applications such as gears, bolts and fasteners.
4140 seamless tubing sizes used in the oil and gas industry for above ground and down hole applications. A519-4140 material is stocked in the annealed, normalized or quenched and tempered conditions. The heat treated material is controlled to L80, P110, Q125 or the customer’s specified properties. The material is weldable but requires a pre-heat before welding.
Applications: The lower cost due to simple chemistry coupled with the physical properties also makes it a good choice for axles, shafts and structural components. However, since the steel has a lower carbon content than other steels, it doesn't harden to the same degree. This makes hard, sharp edges, such as those found in knives, difficult.
Bebon will offer round-shape 4140 seamless tubing non-secondary. Welcome to inquiry.
