Mild steel tubes are widely used in various industries due to their excellent mechanical properties, durability, and affordability. Three popular mild steel tube grades are AISI 1020, 4130, and 4140. In this article, we will discuss the material, specification, chemical composition, mechanical properties, steel grade, and application of these three grades. AISI 1020 Mild Steel Tube Material AISI 1020 is a low-carbon steel that contains 0.18% carbon and 0.23% manganese. It is

1020 THICK WALL STEEL PIPE HEAVY WALL STEEL TUBING The steel pipe whose ratio of outer diameter to wall thickness is less than 20 is called thick wall steel pipe. It is mainly used as petroleum geological drilling pipe, cracking pipe for petrochemical industry, boiler pipe, bearing pipe, high-precision structural pipe for automobile, tractor and aviation, etc. The difference between thick wall steel pipe and thin wall steel pipe lies in the thickness of steel pipe wall.
