Product Description
Alloy pipe is a kind of seamless steel pipe, its performance is much higher than that of general seamless steel pipe, because this type of steel pipe contains more Cr, its high temperature resistance, low temperature resistance, corrosion resistance performance is much better than other Steel pipe, so the alloy pipe is widely used in petroleum, aerospace, chemical, electric power, boiler, military and other industries. Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low-alloy steels and high-alloy steels. The difference between the two is somewhat arbitrary: Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.Most commonly, the phrase "alloy steel" refers to low-alloy steels.
Strictly speaking, every steel is an alloy, but not all steels are called "alloy steels". The simplest steels are iron (Fe) alloyed with carbon (C) (about 0.1% to 1%, depending on type). However, the term "alloy steel" is the standard term referring to steels with other alloying elements added deliberately in addition to the carbon. Common alloyants include manganese (the most common one), nickel, chromium, molybdenum, vanadium, silicon, and boron. Less common alloyants include aluminum, cobalt, copper, cerium, niobium, titanium, tungsten, tin, zinc, lead and zirconium.

AISI A519 4130, 4140 Seamless Alloy Steel Pipe
The good strength and its hardenability make alloy 4130 steel seamless round tubing 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 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. Pipes are 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.
