NOTE — Tubing having a wall thickness less than 3 percent of the outside diameter cannot be straightened properly without a certain amount of distortion. The steel used in the mechanical tubing may be cast in ingots or may be strand cast. SP Metal manufactures its products in different sizes, range, type and schedule-class.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

ASTM A Seamless Steel Mechanical Tubing

Pipe flanges Pipe flange are a method of connecting pipes, valves. An analysis of each heat of steel shall be made by the steel manufacturer to determine the percentages of the elements specified; if secondary melting processes are used, the heat analysis shall be obtained from one remelted ingot or the product of one remelted ingot of each primary melt.

Reduce the weight of your product while increasing your physical requirements. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required.


ASTM A519 Seamless Mechanical Tubing

Unless otherwise specified, the manufacturer can be asstm inner and outer surfaces of the pipe coated with anti-rust oil. Outside Diameter Size Range in. 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.

The tubes shall be furnished in the following shapes: The strength and resilience of this ASME SA Alloy Steel Mechanical Tubing has led to their frequent use in high — rise building adtm bridge construction, as well as most vehicles, many home appliances, tools, pipes, non — illuminated signs and railroad tracks.

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.

The datasheet given below provides more details about AISI alloy steel. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. When steel of different grades is sequentially asfm cast, identification of the resultant transition material is required. Within the text, the SI units are shown in brackets or parentheses. AISI alloy steel contains chromium and molybdenum as strengthening agents.

ASTM A carbon and alloy steel mechanical tubing

Wall Thickness as Percent of OD. The steel used in the mechanical tubing may be cast in ingots or may be strand cast.

asym ASTM A Carbon Steel Tubingwhich is produced for heat exchanger applications, offers the process industry a high quality and competitive product concept. This specification covers both seamless hot-finished mechanical tubing and seamless cold-finished mechanical tubing.


In this specification hard or rationalized conversions apply to diameter, lengths and tensile properties.

ID Tolerances apply to dimensions 0. Whether you’ve got a large construction project, or need parts for industrial machinery, our team of steel fabrication consultants will ensure that your project is provided with the parts you need, when you need them. 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. Alloy steels are broken down into two groups: It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

If the order is not specified in the shipment oiled steel, coated with a layer of oil production should remain on the surface. Alloy steels are designated by AISI four-digit numbers. See also Footnote B.

Grades shown in the above list with prefix letter E are normally made only by the basic electric furnace process. The tubing shall be coated with a film of oil before shaping to retard rust when specified. Heat analysis shall be made to determine the percentages of the elements specified. A51 are more responsive to mechanical and heat treatments than carbon steels.
