AISI 4130 Pipe

Siddhgiri Tubes Manufacturer AISI 4130 Seamless Pipe is a higher strength, lighter weight alternative to carbon steel. We are the market leader in ASTM A29 AISI 4130 Seamless Pipe, We produced a full range of rectangles, squares, rounds, and streamlined products. Our AISI 4130 Welded pipe is manufactured has some best features to offer such as precision–designed, finely finished, non – corrosive and more. The low content of carbon in the Chromoly 4130 Pipe facilitates superior welding operations.

ASTM A519 Grade also covers several alloy and carbon steel seamless mechanical piping and tubing grades. The standard ASME SA519 is also acceptable in the manufacturing of pipes. It is manufactured by hot working and then cold finishing the steel into rectangle, square, round, or special shapes. AISI 4130 pipe is made of Grade 4130 which is a steel formula designation indicating medium carbon content with strengthening alloys that contain manganese, silicon, chromium, sulfur, molybdenum, and phosphorus.

Round 4130 Chromoly Seamless Mechanical Pipes Benefits: High strength to weight ratio, superior tensile strength to mild carbon steel, Heat treatable to a broad range of machinability, strength, and hardness.
