SA179tubes.com specialises in high-quality products and services for the oil and gas industry. In order to provide excellent customer service and on-time order processing, we strive to be the best 4140 alloy steel tube supplier in the industry.

A wide range of downhole tools are made from low alloy steel 4140. Alloy steel with a carbon content of 0.38%-0.43% and controlled levels of chromium, molybdenum, manganese, silicon, phosphorus, and silicon.

 

In 4140 alloy tubing was more economical than stainless steel. 4140 Alloy Tubing is primarily composed of carbon, manganese, potassium, sulphur, silicon, chromium, and molybdenum. These tubes are suitable for medium to high corrosion-induced environments. 

Alloy 4140 tubing is resistant to crevice corrosion and acid cracking. They can be easily machined and fabricated to form desired elements. The 4140 alloy tubing is highly ductile and can be easily galvanised or annealed. Cold-rolling or hot-rolling can easily be used to produce these tubes. 

They can be ordered in lengths up to 13500 mm. 4140 Alloy Tubing has superior mechanical properties and strength. These Tubes have a minimum tensile strength of 655 Mpa and a minimum yield strength of 415 Mpa. All 4140 Alloy Tubing Suppliers follow the same standard processes and tests when producing the best products.

A variety of shapes and sizes are available in this grade of Tube. The 4140 alloy tubing is highly versatile and is commonly used for connecting rods, pump shafts, torsion bars, etc. Steel round Tubes are available in schedules SCH 5 to SCH 160 and SCH XXS. DIN 1.7218 Steel Round Tube exhibits exceptional tolerances and dimensional accuracy. The melting point of these Tubes is 1416 degrees C, and they have a density of 7.85 grams per cubic centimetre. As a 4140 Tube supplier, we offer exceptional prices on all of our products. 

Low alloy steels are ideal for those applications that need to be economical while also being efficient. Cheaper than stainless steel, the small additions of different elements in their chemical composition give them significantly higher mechanical properties. Moreover, there is an increase in exceptional tolerances and dimensional accuracy. 4140 is a type of low steel alloy whose chemical composition includes chromium, molybdenum, and manganese.

Manganese in the chemistry of AISI 4140 Tube improves its toughness, while chromium and molybdenum impart ductility. In addition to its hardenability, this alloy grade has a high tensile strength of 655 MPa. Heat treatment is usually used to improve the mechanical properties of steel alloys. This alloy can be annealed using conventional methods. 

However, because the alloy is tougher than most carbon steel alloys, it requires greater force to form UNS G41400 q & t Tubes.  Grade 4140 is annealed to reduce residual dresses, while also improving their ductility. Suppliers of AISI 4140 Alloy Steel Seamless Tube typically supply these components quenched and tempered. 

As tempering increases the alloy’s hardness and tensile strength, quenching increases its hardness. Due to the alloy’s high toughness and hardness, AISI 4140 qt Alloy steel Square Tubing material tends to resist abrasion better. Therefore, external forces would have a hard time damaging the Tubes’ surface. Torsion strength is also high in the alloy. The SAE 4140 qt Steel Round Tube exhibits high fatigue resistance, which is common for materials.

Fabrication and Heat Treatment

  • Machinability 4140 Alloy Tubing

AISI 4140 alloy steel has good machinability in the 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 steels.

 

  • 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.
