THE USE AND CHARACTERISTICS OF STAINLESS STEEL

Material

Use and characteristics

17 020 

- pipes, exchanger for nitric acid production, welded components of chemical apparatus

17 040 

- lightly stressed equipment exposed to the effects of steam and water, pipes, exchangers used nitric acid production, decorative use

17 240 

- components and equipment in the food, chemical, and fermenting industry, components of cooling equipment away from salt water, air condensation equipment, items produced by deep drawing and spin-shaped, easily cold formable, easily polished

17 249 

- suitable for oxidizing environments – nitric acid at high concentrations and temperatures, in strong anorganic acids it is resistant only at low concentrations and medium temperatures, in weak organic acids up to middle concentration and middle temperatures

17 346 

- equipment for the chemical, textile, pharmaceutical, and paper industries where annealing is not possible after welding; suitable for non-oxidizing environments containing strong organic and strong inorganic acids at lower concentrations up to medium temperatures

17 349 

- dyeing, lacquer, sulphide, chemical, and dairy industry, resistant to concentrated acids and diluted sulphites, ammonium chlorides – easily cold formable and capable of high polish

17 350, 17 352 

- chemical, textile, pharmaceutical, and paper industry equipment, suitable for non-oxidative environments containing strong organic acids at medium to high concentrations and higher temperatures

17 248 

- steel stabilized by titanium, increased resistance to intercrystal corrosion, foodstuffs, consumer industry in the production of nitric acids, wood pulp oils, leather manufacture, engineering and nuclear technology, suitable for oxidation environments for strong anorganic acids at low concentrations and within normal temperatures – the titanium prevents a high polish

17 348 

- steel stabilized by titanium, increased resistance to intercrystal corrosion up to 450°C, equipment for the chemical, pharmaceutical, paper, textile, and rubber industry, nuclear technology, steel suitable mainly for non-oxidative environments containing strong organic and strong anorganic acids in lower concentrations up to medium temperatures, not capable of a high polish.

17 251 

- fire-resistant steel for use in temperatures up to 1000°C, e.g. fire-resistant equipment and tools for the ceramic and glass industries, for hardening shops, annealing shops, and for heat technology, steel is sensitive to gasses containing sulphur, high firmness and tensibility at high temperatures

17 255 

- fire-resistant steel for use at temperatures of up to 1100° C
