Resistance
Water, vapour, humidity, salt, acids in food and
weak organic or inorganic acids.

Applications
Food industry, mechanical engineering,
beverage production, pharmaceutical and
cosmetics industry, chemical apparatus engineering.

Resistance
Better corrosion resistance compared to Cr-Ni
steel, resistant to organic or inorganic acids,
media containing halogen, good resistance to
intercrystalline corrosion. High temperature
resistance up to 450°C.

Applications
Food industry, chemical industry, mechanical
engineering, beverage production,
pharmaceutical and cosmetics industry.

Resistance
Better corrosion resistance compared to Cr-Ni
steel, resistant to organic or inorganic acids,
media containing halogen, good resistance to
intercrystalline corrosion. Improved pitting
corrosion compared to 1.4404 due to the higher
content of molybdenum. High temperature
resistance up to 450°C.

Applications
Food industry, chemical industry, mechanical
engineering, beverage production,
pharmaceutical and cosmetics industry.

Resistance
High corrosion resistance to organic or
inorganic acids. Excellent thermal stability and
corrosion properties at temperatures up to
800°C.

Applications
High pressure engineering, chemical industry,
thermal process engineering. Excellent
properties for applications under high pressure
and temperature, e.g. with high pressure
reactors.

Resistance
Excellent corrosion resistance to reducing
media as e.g. hydrochloric acid in its
complete range of concentrations and
temperatures, acetic acid, hydrogen
chloride, sulphuric acid, phosphoric acid.

Applications
Chemical industry, phenol production.

Resistance
High corrosion resistance to pitting, crevice and
stress at high temperatures under oxidising and
reducing conditions. Resistant to, for example
sulphuric acid, acid mixtures from sulphuric acid,
phosphoric acid, nitric acid, chlorine gas and
oxidising acids with chloride ions.

Applications
Chemical industry, flue gas desulphurisation,
cellulose and paper industry.

Resistance
Depending on the compound superior
chemical resistance to acids, alkalis, amines,
vapour, ethylene oxide as well as many
other aggressive chemicals. Temperature
resistance -20°C to +275°C, at a brief time
+325°C.

Applications
Sealing technology and especially high
vacuum applications.

Resistance
Good chemical resistance to propane, butane and
natural gas, fuels, mineral oils and greases, silicone
oils and greases, and aromatic hydrocarbons.
Temperature resistance -20°C to +250°C, at a brief
time +300°C.

Applications
Sealing technology and especially high vacuum applications.

PTFE, polytetrafluoroethylene

highly resistant plastic
FDA conform

Resistance
Superior chemical resistance because of its
inertness. Extremely resistant to all bases, alcohols,
ketones, benzines.
The thermal capacity ranges from -260°C up to
+250°C, at a brief time +300°C (e.g. no
embrittlement of boiling helium at +269°C).

Applications Chemical industry, apparatus construction, medical
technology.
