Astec Tubes is a well-known manufacturer, supplier, and exporter of steel products, offering AISI 4130 pipes made from low-alloy chromoly steel with chromium and molybdenum that deliver excellent strength, toughness, and weldability. Our pipes are built for high stress applications and are widely used in oil and gas, aerospace, and automotive industries where performance under pressure and resistance to corrosion are critical. Available in both seamless and welded forms, AISI 4130 Seamless Pipes provide durability and reliability in demanding operating conditions, making them one of the most trusted solutions worldwide.
This perfectly balanced composition of 4130 grade pipe gives it strength. About 96–97% of it is iron with molybdenum (0.15–0.25%) adding toughness and heat resistance and chromium (0.80–1.10%) increasing corrosion resistance. Carbon content between 0.38–0.43% gives hardness and wear resistance. Manganese and silicon support ductility and machinability, while sulfur and phosphorus are controlled to ensure weldability and structural integrity.

These properties give AISI 4130 alloy steel seamless pipes a density of 7.85 g/cm³ and a melting point of 1416°C, making them ideal for extreme working environments. To ensure consistency every pipe undergoes strict quality testing. Hardness, flaring, flattening, hydrostatic checks and ultrasonic examination for internal soundness are among the tests. Grain structure is confirmed by macro and micro analysis while radiographic testing reveals hidden defects. Before being used, every pipe is also put through pitting resistance testing and chemical analysis to ensure it meets the highest international standards.
AISI 4130 pipes are a popular choice because of their many benefits. Strong yet lightweight structures are the result of their high strength-to-weight ratio. Its fatigue resistance ensures performance under consistent stress cycles and its weldability simplifies fabrication. Our pipes can be made to proper hardness, toughness, and ductility due to chromium resistance to corrosion and its capacity to endure heat treatment like tempering and quenching. It continues to work even at high temperatures and pressures, offering an affordable choice for manyindustries.

Applications show this adaptability. AISI 4130 grade pipe is used in aerospace for structural elements, engine mounts, and welded tubing. It is essential for hydraulic systems, race car roll cages and even bicycle frames in the automotive and motorsport industries. It contributes to nuclear power plants, high-pressure boilers, petrochemical processing and oil and gas exploration in the industrial and energy sectors. Sporting goods, firearms and important parts for large machinery are some additional applications. Pipes are packed in wooden crates, steel strips or protective covering for safe delivery preventing damage during transportation, and guaranteeing that it arrives at customers' locations in ideal condition.
AISI 4130 alloy steel seamless pipes are manufactured to meet international standards such as ASTM A519 / ASME SA519 for seamless mechanical tubing. It conform to Product Specification Levels (PSL1, PSL2 and PSL3) in oil and gas operations. It is resistant to hydrogen sulphide environments and meet NACE MR 0175 / ISO 15156 requirements for sour service. A Material Test Certificate (EN10204.3.1) attesting to the mechanical and chemical characteristics of each pipe is provided. In some projects third-party inspections are carried out for added assurance.
Manufacturing methods include seamless extrusion, cold rolling, and cold drawing which guarantee precision, superior finish, and enhanced strength. Heat treatments such as annealing, normalizing and quenching are used to adjust hardness and toughness according to application needs. Every AISI 4130 and A519 4130 pipe is made with dimensional accuracy and flawless finishing. Besides AISI 4130 we offer dependable and certified products for a variety of industries, including A29 AISI 4140 Pipe, AISI 4140 Grade L80 Pipes and A519 4140 Alloy Steel Seamless Pipe and Tubes.
