A519 gr 4140 Seamless Steel Tubing is an alloy steel grade which contains elements like chromium-, molybdenum-, and manganese. The ASTM A519 Grade 4140 is low alloy steel, which offers superior characteristics. For instance, some of the vital characteristics of specified A519 4140 Chrome Alloy Steel Hf Smls Tubing include high fatigue strength, high abrasion and impact resistance, along with good toughness, and torsional strength properties. As typical of this alloy steel, this particular specified Alloy Steel A519 4140 Square Tubing material could be welded using all conventional shop practices. However, the mechanical properties of this ASTM A519 Grade 4140 pipe tend to get affected these tubes are welded in the heat-treated condition. Hence, a post-weld heat treatment must be conducted on the ASTM A519 Grade 4140 Mechanical Tubing.
The A519 gr 4140 Seamless Tubing manufactured under this specification is a tubular product made without a welded seam. The tubes are usually manufactured by hot working the steel. And if necessary, the A519 Grade 4140 Steel Tubing can be produced by subsequently cold finishing the hot worked product i.e. the ASTM A519 tube in order to achieve not only the desired shape, but also the desired dimensions and properties. The A519 4140 Hot Finished Tubing material can be furnished in any of the following shapes i.e. - round, square or rectangular. Although at our factory, we can manufacture these tunes in special sections, depending on customizations given by our client or on basis of the application for what these tubes are used. Heat analysis is often conducted on the Chrome Moly Steel ASTM A519 4140 Boiler Tubing in order to determine the specified percentages of the elements.
