AISI 4130 seamless pipe is an ideal choice for various industrial uses. It has outstanding mechanical properties and can be machined to a tight tolerance. It is also readily available in many different finishes, including stainless steel, aluminum, and more.
Chemical & Mechanical Properties of AISI 4130 Pipes
AISI 4130 Seamless Pipe is a powerful and versatile type. It has excellent tensile strength and corrosion resistance and is suitable for high-temperature applications. It is available in various countries and can be purchased at an affordable price. These pipes are manufactured using hot steel billets. They are highly durable and can handle chemical utilities, gas, and oil. These pipes can be fabricated in various shapes and sizes. The material is ideal for applications that require resistance welding. They are easy to weld. The low carbon content improves the weldability of the metal. The alloy is also known as chromium-molybdenum steel. It has properties similar to molybdenum steel, such as ductility, toughness, and machinability. The grade is used in the manufacturing of gears and flywheel components.
This seamless pipe is a through-hardening alloy that contains molybdenum and chromium as a fortifier. It is commonly used in structural engineering. It has a low carbon content and is welded easily. The strength of AISI 4130 is adequate to withstand significant stresses. Its modulus of elasticity is 205 GPa. It can be forged and heat-treated to increase its strength. It can retain its power at 500 degrees Celsius. It is considered one of the most vital pipe types in its grade.
Weldability of 4130 seamless pipes
Known for its strong strength-to-weight ratio, this pipe is used to construct various mechanical structures, aircraft, and ground support systems. The alloy contains chromium and molybdenum. Both these elements provide good flexibility. This steel is readily machinable in normalized and tempered conditions. However, machining becomes more difficult as the metal becomes harder. When welding 4130 or 4140 steel, it is essential to consider the heat input. Increasing the voltage or amperage can improve weldability. But, if the heat input is low, brittle microstructures are formed, and the welds have poor flexibility. It is better to cool the weld slowly. AISI 4130 seamless pipe also requires post-weld thermal treatment. This mechanical treatment enhances the oxidation resistance and load-bearing capacity of the tube. Typical treatment temperatures are 150°F to 260°F.
The most common uses of these pipes are in water treatment, fertilizers, high-pressure boiler equipment, and agricultural machinery.
