Siddhagiri Metals and Tubes is a renowned supplier of AISI 4130 alloy in all forms including  Pipe, Tube and Pipe Fittings.

AISI 4130 compound steel contains chromium and molybdenum as fortifying specialists. It has a low carbon content, and subsequently, it can be welded effortlessly.In other Words, AISI 4130 is a low compound steel containing molybdenum and chromium as fortifying operators. We stock all AISI 4130 Pipes, 4130 Tubing, 4130 Flanges, 4130 Pipes Fittings, 4130 Elbow and so forth. The carbon substance is ostensibly 0.30% and with this moderately low carbon content, the amalgam is amazing from the combination weldability point of view. The amalgam can be solidified by warmth treatment. Regular applications for 4130 low amalgam steel incorporate basic utilize, for example, airship motor mounts and welded tubing applications.
