4130 Precision Seamless Steel Tube is a high-strength, low-alloy steel tube manufactured through advanced cold drawing or cold rolling technology. Made from AISI 4130 (Chromoly) steel, it combines exceptional toughness, fatigue resistance, and weldability with precise dimensional accuracy and a smooth internal surface. 4130 precision seamless tubes are widely used in aerospace, automotive, hydraulic, mechanical, and energy industries, where strength, performance, and precision are critical.
