Cortensteeltube.com manufactures 4140 Alloy Tubing in a variety of shapes, sizes, and dimensions. A minimum yield strength of 275MPa and a minimum tensile strength of 485MPa are required for flanges.The specification also includes ASME B16.47, B16.5, and other standards. The diameter of 4140 alloy tubing ranges from 12 inches to 36 inches. Pressure classes range from 150 to 2500, and pressure numbers range from PN6 to PN64. 

Alloy steel F91 flanges contain carbon, manganese, silicon, sulphur, chromium, and molybdenum. Materials containing 4% chromium are more corrosion resistant and have better mechanical properties.As well as ring-type joints, flat faces, and raised faces, 4140 Alloy Tubing is also available. Flanges also perform different functions. There are two classes of 4140 alloy tubing. 

It is less common to use 4140 Alloy Tubing than Class 1. In different applications, slip-on flanges, welded neck flanges, socket weld flanges, and blind flanges are used. Alloy 4140 tubing is used in chemical, petrochemical, oil and gas, petroleum, and other oil and gas transmission lines.

Fabrication and Heat Treatment

  • Machinability 4140 Alloy Tubing

AISI 4140 alloy steel has good machinability in annealed condition.

  • Forming 4140 Alloy Tubing

4140 Alloy Tubing 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 steel.

  • Welding 4140 Alloy Tubing

4140 Alloy Tubing 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 4140 Alloy Tubing

4140 Alloy Tubing is heated at 845°C (1550°F) followed by quenching in oil. Before hardening, it can be normalised by heating at 913°C (1675°F) for a long period of time followed by air cooling.

  • Forging 4140 Alloy Tubing

AISI 4140 alloy steel is forged at 926 to 1205°C (1700 to 2200°F)

  • Hot Working 4140 Alloy Tubing

AISI 4140 alloy steel can be hot worked at 816 to 1038°C (1500 to 1900°F)

  • Cold Working 4140 Alloy Tubing

AISI 4140 alloy steel can be cold worked using conventional methods in the annealed condition.

  • Annealing 4140 Alloy Tubing

AISI 4140 alloy steel is annealed at 872°C (1600°F) followed by slowly cooling in the furnace.

  • Tempering 4140 Alloy Tubing

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 a lower tempering temperature. For example, tensile strength of 225 ksi can 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 4140 Alloy Tubing

AISI 4140 alloy steel can be hardened by cold working, or heating and quenching.
