ASTM A519 4130 Carbon Steel Seamless Alloy Tubings
ASTM A519 covers several grades of carbon and alloy steel seamless mechanical tubing. The standard is also acceptable in the manufacture of piping. It is manufactured by hot working and then cold finishing the steel into a round, square, rectangle or special shapes. AISI 4130 is a steel formula designation indicating medium carbon content with strengthening alloys that include chromium, manganese, silicon, molybdenum, sulfur and phosphorus.
