ASTM/AISI Standard Alloy Round Bar 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.

Circular steel pipe is both openings and have hollow concentric sections of steel larger than the surrounding. The specifications of steel pipes are indicated by appearance dimensions and inner diameter and wall thickness, with a wide range of dimensions from very small diameter capillary to large round steel pipe of several meters in diameter. Round steel pipes can be used for pipelines, thermal equipment, machinery industry, petroleum geological drilling, containers, chemical industry, and special uses. It can be divided into seamless, ERW, LSAW, SSAW steel pipe according to the production process.
