Product Overview
309Cb belongs to the Austenitic series stainless steel, containing niobium element, which can resist high-temperature oxidation, corrosion and deformation caused by thermal cycling. It has good weldability and machinability.
309Cb is widely used in petrochemical, electric power, pharmaceutical and other industries under high temperature conditions. It is often used in the manufacture of high temperature stoves, petroleum equipment and chemical equipment.

Corrosion Resistance Enhancement
  • Form a stable passivation film on the steel surface. Passivation creates a thin protective film that hinders the anode process, improving chemical stability. Chromium content in the steel increases chromium in the TP309cb stainless steel tube film, enhancing film stability with thickness above 1nm.
  • Obtain a single solid solution structure. For example, 18Cr-8Ni austenitic stainless steel achieves high corrosion resistance only after solution treatment to obtain a single uniform austenitic structure.
  • Increase the electrode potential of the solid solution. Metal corrosion resistance is closely related to medium type, concentration, temperature, pressure, and other conditions, with medium oxidation capacity having the greatest impact.
