AISI 4130 Tubing has higher thermal conductivity and lower thermal expansion than austenitic steels. They can be used without problems at temperatures of at least -50 °C as they have better ductility than ferritic steels at low temperatures. They have lower nickel and molybdenum content than their austenitic counterparts. This lower alloy content means these steels can be more cost effective. In addition, it is also possible that the thickness of this steel can be reduced since it has a higher elastic border. Thinner products mean significant weight savings can be achieved. AISI 4130 Seamless Tubes tends to be readily weldable and all common welding processes can be used although they do not weld as well as the austenitic grades. The extensive advantages of this steel make it versatile: processing, transport and storage of chemicals; pipelines for the production and transportation of oil and gas; etc.
We as Siddhgiri Tubes is a known exporter and distributor of AISI 4130 Tubes, which exceeds the toughness and ductility of ferritic grades, although not as sensitive to touch as austenitic grades. As with all steels, corrosion resistance depends primarily on the composition of the steel, the most important being the chromium, molybdenum and nitrogen content. They are extremely resistant to erosion and even in chloride and sulphur environments. 4130 Steel Tubing exhibit very high resistance to stress corrosion cracking (SCC), a type of erosion that occurs when a specific set of factors are present: tensile stress, corrosive environment and a sufficiently high temperature.
