4130 AISI Welded Pipe

4130 AISI Welded Pipe

The SAE AISI 4130 welded pipe is one type of production where the seamless pipes are most common in usage. The shape of the pipes varies as round, square and rectangular types. We are supplier of lengths for 4130 Seamless alloy steel pipe which can be single random, double random or custom cut to length. There are plain end, beveled end and threaded end types of the pipes with different finishes available. The different pipe types can be finished with annealed and pickled, polished, bright annealed or cold drawn finishes. The AISI 4130 Chromoly Pipe has 0.8 to 1% chromium, molybdenum, sulfur, phosphorus, manganese, silicon and carbon in the composition.

AISI 4130 Round Pipes

Table of Content


The minimum yield strength of the pipes is 460MPa and the minimum tensile strength is 560MPa with 21.5% elongation rate. The Werkstoff Nr. 1.7218 Pipe  also has 95 HRB hardness. The material also has higher temperature tolerance due to the high melting point. The melting point of the UNS G41300 Pipe is 1432 degrees Celsius and therefore it can be used in boiler, heat exchanger and superheater elements. The most applications of the AISI 4130 Alloy steel pipe can be seen in the oil and gas, pharmaceutical, chemical, aerospace, desalination, power generation and in structural engineering applications.
