Chromium-Nickel austenitic steel
12x18Н10Т and 10x17Н13М2Т
Stainless steel of these brands have high corrosion resistance in a wide range of aggressive environments. In the result of heat treatment (heating to 1000 °C and rapid cooling in water or air), they become a homogeneous austenite structure, good plasticity and high corrosion resistance.
03x18Н12 and 03x19Н11
Special corrosion resistance, in particular in concentrated nitric acid and high corrosion resistance of the weld are austenitic steel with low carbon content 03x18Н12 and 03x19Н11. This allows their use for the manufacture of various chemical equipment that operates in corrosive environments.
Steel, alloyed with molybdenum
High corrosion resistance to organic acids (lactic, oxalic, acetic) are chromium-Nickel alloys with additives of molybdenum 08x17Н13М2Т, 10x17Н13М2Т, 08x18Н13М3Т, 08x17Н15М3Т. The percentage of molybdenum is indicated by the digit after the letter M. However, such steel is not strong enough when heated to 600−700°C. the Presence of the ferritic phase reduces their corrosion resistance to nitric acid of high concentrations. For parts that operate in solutions of phosphoric acid, used steel 03x21Н21М4ГБ. It is most often used for the manufacture of welded equipment in the production of phosphorus fertilizers, where to use phosphoric acid with admixtures of fluoride.
