is tubing made to the pipe schedule. Alloy pipe in the power industry generally refers to A335 material, but in the oil and gas market, is used. This product is made to the pipe schedule but uses A519-4140 as the controlling Seamless specification. The material is then heat treated to L80, P110 or the customer’s specified properties. This material is easily welded and is generally used for above ground applications and utilizes the fittings, flanges and other piping components with the same 4140 chemistry. This product is a good alternative to replace X65 through X80 piping items where the usage or repair is too small for mill production.

is a low alloy steel containing molybdenum and chromium as strengthening agents. We stocks all AISI 4140 Pipes, 4140 Tubing, 4140 Flanges, 4140 Pipes Fittings, 4140 Elbow etc. The carbon content is nominally 0.30% and with this relatively low carbon content the alloy is excellent from the fusion weldability standpoint. The alloy can be hardened by heat treatment. Typical applications for 4140 low alloy steel include structural use such as aircraft engine mounts and welded tubing applications.

AISI 4140 Alloy Steel (UNS G41400)

Alloy steels are designated by AISI four-digit numbers. They are more responsive to mechanical and heat treatments than carbon steels. They comprise different types of steels with compositions which exceed the limitations of B, C, Mn, Mo, Ni, Si, Cr, and Va in the carbon steels.

Fabrication and Heat Treatment
Machinability A519 4140 Alloy Steel Seamless Pipe and Tubes
AISI 4140 alloy steel has good machinability in the annealed condition.

Forming A519 4140 Alloy Steel Seamless Pipe and Tubes
AISI 4140 alloy steel has high ductility. It can be formed using conventional techniques in the annealed condition. It requires more pressure or force for forming because it is tougher than plain carbon steels.

Welding A519 4140 Alloy Steel Seamless Pipe and Tubes
AISI 4140 alloy steel can be welded using all conventional techniques. However, the mechanical properties of this steel will be affected if it is welded in the heat treated condition, and post weld heat treatment should be performed.

Heat Treatment A519 4140 Alloy Steel Seamless Pipe and Tubes
AISI 4140 alloy steel is heated at 845°C (1550°F) followed by quenching in oil. Before hardening, it can be normalized by heating at 913°C (1675°F) for a long period of time followed by air cooling.

Forging A519 4140 Alloy Steel Seamless Pipe and Tubes
AISI 4140 alloy steel is forged at 926 to 1205°C (1700 to 2200°F)

Hot Working A519 4140 Alloy Steel Seamless Pipe and Tubes
AISI 4140 alloy steel can be hot worked at 816 to 1038°C (1500 to 1900°F)

Cold Working A519 4140 Alloy Steel Seamless Pipe and Tubes
AISI 4140 alloy steel can be cold worked using conventional methods in the annealed condition.

Annealing A519 4140 Alloy Steel Seamless Pipe and Tubes
AISI 4140 alloy steel is annealed at 872°C (1600°F) followed by slowly cooling in the furnace.

Tempering A519 4140 Alloy Steel Seamless Pipe and Tubes
AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has lower tempering temperature. For example, tensile strength of 225 ksi cab be achieved by tempering at 316°C (600°F), and a tensile strength of 130 ksi can be achieved by tempering at 538°C (1000°F).

Hardening A519 4140 Alloy Steel Seamless Pipe and Tubes
AISI 4140 alloy steel can be hardened by cold working, or heating and quenching.
