Generally, the seamless pipe is made of high-quality carbon steel such as 10# , 20# , 30# , 35# , 45# , such as low-alloy structural steel such as 16Mn and 5MnV, or hot-rolled or cold-rolled steel of 40Cr, 30CrMnSi, 45Mn2, and 40MnB.

The molybdenum in A519 4140 tubing is very useful as it helps immensely in the resistance of corrosion due to chlorides. The manganese that is present in A519 4140 seamless tubes is extremely helpful as it acts like a deoxidizer and it also increases the

ASTM 4130 Sch80 pipe is a kind of chromium-molybdenum general purpose alloy steel tubing. This material is weldable and is capable of developing good strength. 4130 Sch80 seamless pipe has been for years the standard of the aircraft industry.

Our A519 4140 seamless tubes are available in a wide variety of sizes, range, type, and schedule-class. A519 4140 seamless mechanical steel tube uses include the manufacture of hydraulic cylinders for heavy equipment.
