AISI 4130 is a type of steel that has high forms and ductility properties; hence it is ideal in the manufacture of different 4130 pipe fittings including straight tees, reducing tees, long-radius tees, 3R tees, caps, and reducers. AISI 4130 alloy steel reinforcing elements like chromium and molybdenum are provided to strengthen it. Having low carbon level, AISI 4130 fittings are easily welded. The pipe fittings of AISI 4130 steel are easily machinable with the help of conventional tools and offer smooth finish and high accuracy. The characteristics of AISI 4130 pipe fittings are peculiar, such as design accuracy and anti-corrosion. The AISI SAE 4130 fittings are highly corrosive and wear-resistant as well as fitting well in applications that have high stresses. SAE 4130 pipe fittings can be used in piping systems to link straight pipe or tubing, change size or shape and to control the flow of fluids. The process of changing the direction of the pipe by bending can be used, but this may result in deformation, stretching the outer wall and thickening the inner one. Installation of AISI 4130 line fittings will allow the accurate and stable connections that will guarantee the highest level of working without the destruction of the integrity of the pipe system.

Frequently Asked Questions About AISI 4130 Pipe Fittings

What is the purpose of tempering in UNS G41300 elbow?
Tempering of the UNS G41300 Elbow is done to relieve stresses induced by the hardening process. This treatment ensures the required mechanical properties are achieved for the final application, which may vary based on client specifications.
How is werkstoff nr. 1.7218 reducer manufactured and machined?
The Werkstoff Nr. 1.7218 Reducer is made from SAE 4130 low alloy steel, which offers good machinability. Simple shapes like AISI 4130 elbows are machined after normalizing, while more complex shapes such as SAE 4130 pipe elbows need annealing. To achieve optimal machinability, a coarse pearlitic structure with minimal ferrite is recommended.
What are the applications & properties of aisi 4130 fittings?
AISI 4130 fittings are made from low-alloy 4130 steel, known for its excellent mechanical properties. With a density of 7.85 g/cm³, AISI 4130 reducers are used in structural applications, especially in aerospace and construction. These fittings can be easily cold worked, hot worked, or forged but cannot be aged.
