AISI 4140 Seamless Pipe is tubing made to the pipe schedule. Alloy pipe in the power industry generally refers to A335 material, but in the oil and gas market, 4140 Pipe is used. This product is made to the pipe schedule but uses A519-4140 as the controlling Seamless specification. The material is then heat treated to L80, P110 or the customer’s specified properties. This material is easily welded and is generally used for above ground applications and utilizes the fittings, flanges and other piping components with the same 4140 chemistry. This product is a good alternative to replace X65 through X80 piping items where the usage or repair is too small for mill production.
AISI 4140 is a low alloy steel containing molybdenum and chromium as strengthening agents. We stocks all AISI 4140 Pipes, 4140 Tubing, 4140 Flanges, 4140 Pipes Fittings, 4140 Elbow etc. The carbon content is nominally 0.30% and with this relatively low carbon content the alloy is excellent from the fusion weldability standpoint. The alloy can be hardened by heat treatment. Typical applications for 4140 low alloy steel include structural use such as aircraft engine mounts and welded tubing applications.
