X6CrNiMoTi17-12-2, 1.4571, AISI 316Ti - application and specification

The austenitic steel X6CrNiMoTi17-12-2 / 1.4571 is titanium-stabilized and resistant to intergranular corrosion, pitting corrosion, and most acids and salts in mild concentrations. It has good weldability and has reasonably acceptable strength qualities at increased temperatures. When compared to X5CrNi18-10 / 1.4301 steel, it has much greater resistance to crevice and pitting corrosion.

Titanium is used in the grade as a supplementary carbide-forming element that aids in maintaining a consistent chromium concentration during heat treatment and avoids intergranular corrosion during welding. The 1.4571 steel has a high thermal expansion coefficient and is more resistant to high temperatures, but it is prone to deformation due to its poor heat conductivity, especially at smaller dimensions.

After heat treatment, AISI 316Ti can display magnetism when compared to other austenitic steels. Cold bending and pressing are not an issue since the steel has high ductility and plasticity. It's worth noting that steel does not require any extra heat operations after welding and may operate at temperatures as low as 870 degrees Fahrenheit. Materials in the aforementioned group of materials are difficult to treat mechanically.

The X6CrNiMoTi17-12-2 grade is resistant to hot sulfuric acid solutions, boiling organic acids, nitric acid and sulfuric acid reagents, sulphur dioxide environments, phosphoric acid at room and low temperatures, orthoboric acid, benzoic acid, formic acid, tartaric acid, lactic acid, oleic acid, acids used in the food industry, acetic acid, and a variety of hydroxides. Salts such as nitrates, borates, bromides, and chlorides fall under this category. 316Ti should not be used in settings with hydrochloric, nitric, or hydrofluoric acid solutions.

Steel is used in the shipbuilding, chemical, dyeing, brewing, off-shore, pharmaceutical, textile, petrochemical, plastics, and paper industries, as well as in the manufacturing 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, and in the construction of balustrades, frames, and ornaments.
