ASTM/ASME Standard Alloy Pipes AISI 4140 is a chromium molybdenum alloy steel specification widely used in the oil and gas industry. Similar to grade AISI 4130 but with a slightly higher carbon content. American Iron and Steel Institute (AISI 4140) is a member of the low alloy tool steel family characterized by small quantities of trace elements added to an otherwise simple steel. These trace elements, when compared with more simple steel such as 1040, improves the characteristics of 4140 . However, because 4140 remains relatively simple, it is used in a wider range of applications than more specialized tool steels like the D or S series of steel. Heat Treatment AISI 4140 has enough carbon present to allow for adequate heat treatment. Recommended hardening procedures are to bring the steel up to 1,675 degrees Fahrenheit for normalization (removal of stress within the steel). After it cools properly, heat the steel to 1,550 degrees Fahrenheit before quenching it in oil. The toughness of the steel makes machining in its hardened form difficult. However, after annealing the steel at 1,600 degrees followed by a slow cooling, the steel is much softer and far easier to machine. It can then be heat-treated after machining to produce a hard, precise item. Applications

ASTM/ASME Standard Alloy Pipes AISI 4130 is a low alloy steel containing molybdenum and chromium as strengthening agents. The carbon content is nominally 0.30% and with this relatively low carbon content the alloy is excellent from the fusion weldability standpoint. The ASTM A519 4130alloy can be hardened by heat treatment. We offers an extensive range of ASTM A519 4130seamless mechanical tubing is manufactured to meet your specific application requirements. Controlled modifications and adjustments are made to the tube making process for each order and take into consideration end use and all finishing operations (including heat treatment) that will be performed after you have received the tubing. General Scope This grade is similar to 4140 in scope which has a higher carbon level giving 4130 an advantage when it comes to weldability, this weldability is achieved at the cost of through section hardenability. AISI 4130 steel is a low alloy steel that is used in structural designs that may be found in applications such as aircraft engine mounts or welded tubing. It is well known for its ease of welding and ability to harden in commercial applications. It is commonly referred to as chromium-molybdenum steel.
