Ronsco - Model 1.4435 - Austenitic Stainless Steel
1.4435 isaustenitic chromium-nickel stainless steels containing molybdenum. This addition increases general corrosion resistance, improves resistance to pitting from chloride ion solutions, and provides increased strength at elevated temperatures. Corrosion resistance is improved, particularly against sulfuric, hydrochloric, acetic, formic, and tartaric acids.

1.4435 products are characterized by resistance to high temperatures, high plasticity, ductility, and relatively good ductility. They are suitable for compression, cold and tensile hardening to produce springs and spring elements from strips or wires. The materials show non-magnetic properties in soft condition, relatively good mechanical properties in cryogenic temperatures and good weldability not requiring additional heat treatment processes. It is also important to note the relatively low mechanical properties, which are not conducive to mechanical applications, and the difficult machinability of steel.
1.4435 is suitable for use in the environment of phosphoric, nitric, citric, lactic, formic, acetic acids, in the presence of alkalis - hydroxides, and salts - nitrates, chlorides, fluorides, acetates and sulphates. The grade also shows resistance to the marine environment and salts. The steel is not resistant to chloric acid, orthophosphoric acid, formic acid in high concentrations, sulphuric acid and hydrochloric acid.
1.4435 is widely used in the oil, nitrogen, shipbuilding, chemical, construction, refinery, medical, cellulose, cryogenic, automotive, as well as food processing industries for parts of gas installations, heat exchangers, railings, ship equipment and public transport vehicles, valves, tanks, pumps, radiators, food processing machines in dairy, catering, meat plants, vegetable and fruit processing plants, distillers, chimneys, steam systems, pipelines, pressure equipment, crystallizers, cisterns, silos, swimming pools, boiler parts, condensers, autoclaves, reactors or condensing equipment.
