Therefore, we are the go-to source for ASTM A519 Seamless Mechanical Steel Tubing. Here are a few reasons why so many rely on Solitaire Overseas to meet their needs
ASTM 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 ASTM 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 ASTM 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 ASTM A519 Grade 4140 Steel Tubing can be produced by subsequently cold finishing the hot worked product i.e. the ASTM A519 Grade 4140 tube in order to achieve not only the desired shape, but also the desired dimensions and properties. The ASTM A519 Steel Tube 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 Steel Tube Grade 4140 Boiler Tubing in order to determine the specified percentages of the elements.
This ASTM A519 Steel Tube specification covers several grades of carbon and alloy steel mechanical tubing, either hot-finished or cold-finished. ASTM A519 grade 4140 (with IBR Test Certificate) mechanical tubing is used for mechanical and pressure applications and for transportation of steam, water, and gas. ASTM A519 Steel Tube available grades include 1026, 4130, 4140. It covers several grades of carbon or alloy steel mechanical tubing, hot or cold-rolled.

Stress Relieved Ultimate Strength 105 ksi, 724 Mpa, Yield Strength 85 ksi, 586 Mpa and hardness 95. Annealed Ultimate Strength 75 ksi, 517 Mpa, Yield Strength 55 ksi, 379 Mpa and hardness 81. Normalized Annealed Ultimate Strength 90 ksi, 621 Mpa, Yield Strength 60 ksi, 414 Mpa and hardness 89.
The steel used in the mechanical tubing may be cast in ingots or maybe strand cast. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required. The seamless tubing is a tubular product made without a welded seam. It is usually manufactured by hot working steel, and if necessary, by subsequently cold finishing the hot-worked tubular product to produce the desired shape, dimensions and properties.

ASTM A519 Seamless Tubes is manufactured from carbon and alloy steels for structural or other mechanical purposes involving machining or heat treating, where close tolerances, smooth finish, or definite physical properties are important factors. Micro alloys available upon request. Reduce the weight of your product while increasing your physical requirements. Cold Drawn Seamless stocks are generally carried to OD and ID tolerances, except when the ID is less than 50 percent of the OD. The latter sizes and hot finished seamless stocks are carried in warehouse to OD and wall tolerances.
SPECIAL NOTE: Tolerances are applicable only to two dimensions (length excepted). Thus, if OD and wall are specified, the theoretical ID may not conform to published tolerances except that the mean or average wall (taking into account the permissible OD and ID tolerances) will not vary more than indicated under “DIAMETER AND WALL TOLERANCES.”
EXAMPLE: If a cold drawn tube is specified 1-1/2 inch OD x 1-1/4 inch ID, one might expect the theoretical wall of 1/8 inch to be held to a variation of plus or minus 7-1/2 percent or within the limits of 0.116/0.134 inch.
However, for a nominal OD of 1.500 inch, the OD may vary between 1.500 inch and 1.505 inch, and the ID may vary between 1.245 inch and 1.250 inch, which may result in an average or mean wall of 0.130 inch instead of 1/8 inch. Consequently, the wall may vary plus or minus 7-1/2 percent from the mean of 0.130 inch, or within limits of 0.120/0.140 inch. If, however, the average wall were 1/8 inch (0.125) reflecting 1.500 inch OD and 1.250 inch ID, the wall limits would be plus or minus 7-1/2 percent of 1/8 or 0.116/0.134 inch. Hence, any order of tubes might vary in the entire lot as low as 0.116 inch on some and as high as 0.134 inch on others.
