X6CrNiMoTi17-12-2 / 1.4571 steel is austenitic grade stabilized with titanium, resistant to intergranular corrosion, pitting corrosion, most acids and salts in moderate concentrations. It is characterized by relatively good strength properties at elevated temperatures and good weldability. It exhibits significantly better resistance to crevice and pitting corrosion compared to X5CrNi18-10 / 1.4301 steel
The addition of Titanium in the grade plays the role of the additional carbide-forming element, which helps to maintain a stable concentration of chromium during heat treatment, and prevents intergranular corrosion during welding. The 1.4571 steel has a high thermal expansion coefficient, is more resistant to elevated temperatures, but is susceptible to deformation - especially at smaller dimensions due to inferior thermal conductivity.
Compared to other austenitic steels, AISI 316Ti can exhibit magnetism after heat treatment. The steel is characterized by good ductility and plasticity, cold bending and pressing is not a problem. It is worth adding that steel does not require additional thermal processes after welding and can work at 870 operating temperatures Mechanical treatment of materials in the aforementioned group of materials is difficult.
X6CrNiMoTi17-12-2 grade is resistant to solutions of hot sulfuric acid, boiling organic acids, nitric acid and sulfuric acid reagents, environments containing sulfur dioxide, phosphoric acid at room and low temperatures, orthoboric acid, benzoic acid, formic acid, tartaric acid, lactic acid, oleic acid, acids found in food industry, acetic acid, numerous hydroxides. This also applies to salts - nitrates, borates, bromides and chlorides. 316Ti is not suitable for use in environments containing solutions of hydrochloric, nitric and hydrofluoric acids.
Steel is used in shipbuilding, chemical, dyeing, brewing, off-shore, pharmaceutical, textile, petrochemical, plastics and paper industries, in the production of chemical tanks, heat exchangers, fittings and installations for the production of chemical reagents, components - bolts, nuts working in contact with salts, parts and components of ships and ships, medical implants, surgical implants, springs, in construction for elements of balustrades, frames, ornaments, welded fittings, installations, parts of machines producing rubber.
