Abstract

A ferritic stainless steel, characterized by superior crevice and intergranular corrosion resistance, consists of, by weight, up to 0.08% carbon, up to 0.06% nitrogen, from 25.00 to 35.00% chromium, from 3.60 to 5.60% molybdenum, up to 2.00% manganese, up to 2.00% nickel, up to 2.00% silicon, up to 0.5% aluminum, up to 2.00% titanium, zirconium and/or niobium, balance iron. The sum of carbon plus nitrogen is in excess of 0.0275%. Titanium, zirconium, and niobium, are in accordance with the following equation: %Ti/6+%Zr/7+%Nb/8>/=%C+%N

Description

Изобретение относитс  к черной металлургии, в частности к ферритным нержавеющим стал м.This invention relates to ferrous metallurgy, in particular to ferritic stainless steels.

Целью изобретени   вл етс  снижение себестоимости получени  стали при суммарном содержании углерода и азота более 0,0275 мас,% и сохранение при этом высокой коррозионной стойкости и механических свойств.The aim of the invention is to reduce the cost of steel production with a total content of carbon and nitrogen of more than 0.0275 wt%, while maintaining high corrosion resistance and mechanical properties.

Сталь получают путем аргонокисло- родного обезуглероживани  и примен ю дл  свариваемых деталей, имеющих ТОЛ1ЦИНУ не более 1,7В мм (предпочтительно не более 1,24 мм)j особенно дл  свариваемьк конденсаторных труб, толщина которых составл ет 0,66- 0,97 мм.Steel is produced by argon-oxygen decarburization and is used for welded parts that have a TOL1 of not more than 1.7V mm (preferably not more than 1.24 mm) j, especially for welded capacitor tubes, whose thickness is 0.66-0.97 mm .

Полученные слитки нагревают до 1125 С, в гор чем состо нии прокатывают на лист ТОЛ1ЦИНОЙ 3,18 мм, отжигают при 1060-1125 С, в холодном состо нии прокатывают на лист толщиной 1,57-1,65 мм и отжигают при 1060- 1125 С. Затем одни образцы подвергают испытаг:лю на стойкость против коррозии , а другие сваривают при помощи дуги вольфрамовым электродомThe resulting ingots are heated to 1125 ° C, rolled into a sheet in hot condition with a TOL1TSINO of 3.18 mm, annealed at 1060-1125 ° C, in a cold state rolled into a sheet of 1.57-1.65 mm thick and annealed at 1060-125 C. Then, some samples are subjected to a test: Liu for resistance to corrosion, while others are welded using an arc with a tungsten electrode

в среде инертного газа и испытывают на стойкость.in an inert gas environment and tested for durability.

Испытанные образцы имеют свойст- ва, сходные со свойствами ферритной нержавеющей стали, полученной вакуумной плавкой.The tested specimens have properties similar to those of ferritic stainless steel produced by vacuum melting.
