Grade AISI 4130 is a low alloy steel pipe that contains elements such as chromium and molybdenum added to its allot as strengthening agents. As compared to conventional carbon alloy pipes, the AISI 4130 Pipe is more receptive to treatments either by heat or by mechanical means. The low content of carbon in AISI 4130 facilitates superior welding operations.
The good strength and its hardenability make chromoly 4130 pipe a good fit for applications that deal with structural employment. If this low alloy steel is manufactured using specification ASTM A519, they are either hot finished or they may be cold finished. If the ASTM A519 Grade 4130 Chromoly Pipe is to be a part of mechanical tubing, they could be strand cast or cast in ingots. 4130 Alloy Steel Seamless Pipe is customarily contrived by hot working steel. If imminent, these hot worked tubular pipes are subsequently cold finished in order to construct the solicited dimensions, shape or properties.
Chromoly pipe is commonly furnished in any one of the following shapes - square, round, rectangular as well as sections of a specific nature. To circumscribe the portions of the elements specified, a heat analysis could be employed. The 4130 Chromoly Steel Pipe could be coated with a film of oil before the performance of any shaping operation. Coating is applied on these pipes to hinder rust if specified by the buyer.
