Product Description

Product Description

12X18H10T is Chrome-nickel stainless steel with addition of titanium with increased hardness, elasticity, maintaining non-magnetic properties, resistance to intergranular corrosion and increased temperatures. It is characterized by significant resistance to nitric-acid, nitric-acid salts in high concentrations and temperatures, cold solutions of salts, toluene, sulphuric acid, phosphoric acid, acetic acid, formic acid and a large portion of organic acids. It is worth mentioning about the very good impact strength maintained at low temperatures, sufficient ductility of the materials, as well as increased resistance to pitting and crevice corrosion due to the content of titanium in the chemical composition. It is used in the chemical, food, cryogenic, nitric, aerospace, paper and fuel industries for pressure vessels, liquid installations, tanks, pipelines, fittings, components of equipment and machinery in food processing, silos and tanks for the production of chemical compounds, radiators, heat exchangers, corrosion-resistant springs, parts requiring increased strength in structures, and autoclaves. The steel is distinguished by its good weldability.
