High Precision Aisi 1020 Cold Drawn Carbon Seamless Steel Pipe

Cold Drawn Seamless Steel Pipe

The High Precision AISI 1020 Cold Drawn Carbon Seamless Steel Pipe is a product renowned for its exceptional strength and durability, making it suitable for a wide range of industrial applications. The chemical composition comprises carbon, manganese, phosphorus, and sulfur; specifically, the carbon content ranges from 0.18% to 0.23%, while manganese is present in amounts between 0.3% and 0.6%. The maximum allowable limits for phosphorus and sulfur are set at 0.03% and 0.05%, respectively.

In terms of mechanical properties, this product exhibits outstanding characteristics in both hot-rolled and cold-drawn states. The hot-rolled variant demonstrates a tensile strength of 380 MPa, yield strength of 210 MPa, with an elongation percentage of 25%. Conversely, the cold-drawn version achieves a tensile strength of 460 MPa, yield strength of 350 MPa, along with an elongation rate of just 15%. Both variants exhibit area reductions of approximately 50% and 40%, respectively, alongside a hardness rating measured at HB111.

● As a high precision product, it plays an integral role across various sectors including automotive manufacturing, construction industries, energy production as well as general manufacturing.
