What are ASTM A519 4130 Tubes?

ASTM A519 4130 Tubes are one type of seamless mechanical tube made from chromium-molybdenum alloy steel containing 0.30% carbon. In addition to alloy composition of chromium and molybdenum elements, ASTM A519 Grade 4130 Steel Tubing is characterized by high strength to weight ratio, great toughness and fatigue resistance. These seamless mechanical tubing can be used for aviation space frames, Automotive industries, cylinders of hydraulic press equipment, pressure vessels and mechanical engineering, etc.

AISI 4130 Chromoly Seamless Mechanical Tubing

ASTM A519 4130 Tubes are high-strength low-alloy chromium-molybdenum steel tubes widely used in demanding industrial applications requiring superior strength, toughness, weldability, and fatigue resistance. Known for their excellent mechanical properties, ASTM A519 Grade 4130 Steel Tubing is extensively utilized in aerospace, oil & gas, automotive, power generation, construction, hydraulic systems, and engineering applications.
