Abstract
Description
Изобретение относится к области черной металлургии, в частности к составам сталей, которые могут быть использованы в судостроении.The invention relates to the field of ferrous metallurgy, in particular to compositions of steels that can be used in shipbuilding.
Известна сталь, содержащая, мас.%: углерод 0,2-2,5; кремний ≤0,1; марганец 0,1-1,5; хром 2,0-20,0; никель 0,01-2,0; молибден 0,1-5,0; азот ≤0,02; медь 0,025-1,0; титан ≤2,0; ванадий 0,01-5,0; цирконий ≤2,0; железо - остальное [1].Known steel containing, wt.%: Carbon 0.2-2.5; silicon ≤0.1; manganese 0.1-1.5; chrome 2.0-20.0; nickel 0.01-2.0; molybdenum 0.1-5.0; nitrogen ≤0.02; copper 0.025-1.0; titanium ≤2.0; vanadium 0.01-5.0; zirconium ≤2.0; iron - the rest [1].
Задачей изобретения является повышение коррозионной стойкости стали.The objective of the invention is to increase the corrosion resistance of steel.
Технический результат достигается тем, что коррозионно-стойкая сталь, содержащая углерод, кремний, марганец, хром, никель, молибден, азот, медь, титан, ванадий, цирконий, железо, дополнительно включает германий при следующем соотношении компонентов, мас.%: углерод 0,15-0,25; кремний 0,1-0,3; марганец 0,6-1,0; хром 22,0-26,0; никель 4,0-5,0; молибден 2,0-3,0; азот 0,02-0,06; медь 0,1-0,3; титан 0,75-1,25; ванадий 0,3-0,5; цирконий 1,0-1,5; германий 0,003-0,008; железо - остальное.The technical result is achieved by the fact that corrosion-resistant steel containing carbon, silicon, manganese, chromium, nickel, molybdenum, nitrogen, copper, titanium, vanadium, zirconium, iron, additionally includes germanium in the following ratio, wt.%: Carbon 0 15-0.25; silicon 0.1-0.3; manganese 0.6-1.0; chrome 22.0-26.0; nickel 4.0-5.0; molybdenum 2.0-3.0; nitrogen 0.02-0.06; copper 0.1-0.3; titanium 0.75-1.25; vanadium 0.3-0.5; zirconium 1.0-1.5; germanium 0.003-0.008; iron is the rest.
В таблице приведены составы стали.The table shows the compositions of steel.
В стали компоненты проявляют себя следующим образом. Никель, ванадий и молибден упрочняют твердый раствор. Медь способствует дисперсионному твердению. Титан образует карбонитриды, которые придают мелкозернистость структуре стали. Германий в структуре стали имеет вид мелкораздробленных включений, которые, находясь между частицами металла, способствуют "изоляции" очагов межкристаллитной коррозии. Вследствие присутствия в составе стали примесей серы введение циркония способствует образованию сульфидов циркония, выполняющих аналогичную функцию.In steel, the components manifest themselves as follows. Nickel, vanadium and molybdenum strengthen the solid solution. Copper promotes dispersion hardening. Titanium forms carbonitrides, which give a fine-grained steel structure. Germanium in the structure of steel has the form of finely divided inclusions, which, being between metal particles, contribute to the "isolation" of foci of intergranular corrosion. Due to the presence of sulfur impurities in the steel, the introduction of zirconium promotes the formation of zirconium sulfides, which perform a similar function.
Скорость коррозии стали в морской воде составит ~0,002 мм/год для всех приведенных в таблице составов.The corrosion rate of steel in sea water will be ~ 0.002 mm / year for all the compositions listed in the table.
Сталь может быть выплавлена в электропечах. Термическая обработка стали включает закалку при температуре 850°С в масло и отпуск при температуре 530°С.Steel can be smelted in electric furnaces. Heat treatment of steel includes quenching at a temperature of 850 ° C in oil and tempering at a temperature of 530 ° C.
