Ready Stock of ASTM A519 4130 chromoly Tubing

ASTM A519 4130 chromoly Tubing is chromium molybdenum added alloy steel pipes that are intended for strength and corrosion resistance. The low carbon content allows the pipes to be welded with ease and reduced carbide precipitation. The material is also receptive to most heat and mechanical treatments. The AISI 4130 Tube has 460 MPa minimum yield strength and 560 MPa minimum tensile strength with 20% elongation at break. The material has nickel, chromium, molybdenum, manganese, silicon, iron, sulfur phosphorus and chromium in the composition. This allows the AISI 4130 Welded Pipes to have 2580 degrees Fahrenheit melting point which in turn provides high heat resistance.

Wide range of 4130 Chromoly Tubing specifications

The pipes belong to the ASTM A29 and ASME SA29 specifications. The standards are according to ASTM, ASME and API standards. The size of the tubes range from 4mm to 219 mm for seamless pipes and the wall thicknesses range from 0.5mm to 20mm. There are round, square and AISI 4130 Rectangular Pipes along with hydraulic and U tubes. These pipes are specialized in larger diameter sizes. The length can be single random, double random and custom cut to length sizes up to 13500mm. The seamless, ERW, fabricated and welded pipes are available for various applications. The 4130 chromoly steel tubing can have plain end, beveled end and treaded ends for fitting with different types of piping components. The applications that require high strength such as structural applications use these pipes. There are different coatings available as required as well.
