| Material | austenitic stainless steel |
| Standard | EN 10088-1 |
| Grade | 1.4301 |
| Main properties and application | 1.4301 stainless steel is the universal and the most widely used austenitic steel in the industry; weldability is good, but due to the lack of titanium, the weld seam (except for contact welding) is subject to intergranular corrosion; Steel 1.4301 is used more widely when subsequent heat treatment (hardening) and cold deformation is necessary, as parts of furnace fittings, heat exchangers, muffles, rotors, nozzles and collectors of exhaust systems, electrodes of spark plugs, etc.; weakly magnetic, practically non-magnetic in the heat-treated state; good resistance to atmospheric and intergranular corrosion in combination with heat resistance, stability, strength, ease of processing, the possibility of use in a wide range of temperatures made this brand of steel one of the most produced and used around the world in various industries, including for the manufacture of machine parts and food and trade machine-building equipment, consumer goods.
Chemical composition and main properties of wire steel grade EN 1.4301 (X5CrNi18-10) according to ЕN 10088-3:2014 corresponds to the requirements to steel grade ISO name X5CrNi18-10 (number 4301-304-00-I) according to ISO 15510-2014 and steel grade AISI 304 of ASTM A580-18. |
| Operating temperature | the recommended operating temperature is not more than 420 ° C in terms of corrosion resistance; not more than 710°С in terms of mechanical parameters; melting point 1400°С |
| Grade analogue | ISO: 4301-304-00-I (X5CrNi18-10); Poland (PN): 1H18N9T; AISI 304L; AISI 304H; SS304; SS304L; UNS S30403; stainless steel 18/10 |
| Density | 7.92 g/cm3 |
| Corrosion resistance | EN 1.4301 stainless steel has good resistance to atmospheric and intergranular corrosion, including in saturated steam, when operating at high and low temperatures and in aggressive environments, in solutions of nitric, acetic, phosphoric acids, alkali solutions and salts, in sea water; steel grade 1.4301 is recommended for use as corrosion-resistant; used in highly aggressive environments; steel grade 1.4301 is unstable in sulphurous environments |
| Notes regarding corrosion | atmospheric corrosion resistance: 4500 times higher than ordinary quality low carbon steel without coating, 500 times higher than zinc galvanized low carbon steel, 50 times higher than aluminum, higher than brass 25 times. PREN (PEPC - Pitting Resistance Equivalent): 20 |
