ASTM A519 4140 steel pipe is a seamless alloy steel pipe made from 4140 grade steel. 4140 steel is a low alloy steel that contains chromium, molybdenum, and manganese. This steel grade has high strength and toughness, making it a popular choice for applications that require high tensile strength, such as in the construction of heavy equipment, machinery, and oil and gas drilling tools. The seamless nature of this pipe makes it suitable for applications that require high pressure, such as in the oil and gas industry. The ASTM A519 standard specifies the requirements for seamless carbon and alloy steel mechanical tubing.
