Seamless circular steel tubes for mechanical and general engineering purposes - Technical delivery conditions - Part 2: Stainless steel
X6CrNiMoTi17-12-2, 1.4571, AISI 316Ti, UNS S31635 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 steelThe 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.
X6CrNiMoTi17-12-2, 1.4571, AISI 316Ti, UNS S31635 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.
