ASTM A519 Alloy Steel Tube Suppliers

ASTM A519 AISI 4130 Alloy Steel Tube

ASTM A519 Tube is where precision finish dimensions and surface quality is of secondary importance. It is a cost effective alternative. Hot Finished Seamless tube is designed for machining high strength and close tolerance projects. Typically seen in bushings, axles, hydraulics and sleeve applications. An industry standard for manufacturing AISI 4130 tube is OD and wall dimensions. Stocked through a wide range of sizes, in either mechanical tube, casing or DOM (drawn over mandrel) product forms. These grades of AISI 4130 steel containing Chromium and Molybdenum are the most widely used alloys for oil patch applications.

Scope And Manufacturing

ASTM A519 specification refers to AISI 4130 Steel seamless mechanical tubing. When welding is used for joining the weldable mechanical tube grades, the welding procedure shall be suitable for the grade, the condition of the components, and the intended service. The steel may be made by any process. If a specific type of melting is required by the purchaser, it shall be as stated on the purchase order. The primary melting may incorporate separate degaussing or refining, and may be followed by secondary melting,such as electroslag or vacuum-arc remelting. If secondary melting is employed, the heat shall be defined as all of the ingots remelted from a single primary heat. Steel may be cast into ingots or may be strand cast. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required. The producer shall remove the transition material by an established procedure that positively separates the grades. Tubes shall be made by a seamless process and shall be either hot finished or cold finished, as specified. Seamless tubing is a tubular product made without a welded seam. It is manufactured usually by hot working steel and, if necessary, by subsequently cold finishing the hotworked tubular product to produce the desired shape, dimensions and properties.
