Material Process connection and thermowell
The temperatures for continuous operation specified in the following table are only intended as
reference values for use of the various materials in air and without any significant compressive load.
The maximum operation temperatures are reduced considerably in some cases where abnormal
conditions such as high mechanical load occur or in aggressive media.

for continuous
use in air Properties
AISI 316/
1.4401 X5CrNiMo17-12-2 650 °C (1 202 °F)
1)
• Austenitic, stainless steel
• High corrosion resistance in general
• Particularly high corrosion resistance in chlorine-
based and acidic, non-oxidizing atmospheres through
the addition of molybdenum (e.g. phosphoric and
sulfuric acids, acetic and tartaric acids with a low
concentration)
AISI 316L/
1.4404
1.4435 X2CrNiMo17-12-2
X2CrNiMo18-14-3 650 °C (1 202 °F)
1)
• Austenitic, stainless steel
• High corrosion resistance in general
• Particularly high corrosion resistance in chlorine-
based and acidic, non-oxidizing atmospheres through
the addition of molybdenum (e.g. phosphoric and
sulfuric acids, acetic and tartaric acids with a low
concentration)
• Increased resistance to intergranular corrosion and
pitting
• Compared to 1.4404, 1.4435 has even higher
corrosion resistance and a lower delta ferrite content
Alloy600 NiCr15Fe 1 100 °C (2 012 °F) • A nickel/chromium alloy with very good resistance to
aggressive, oxidizing and reducing atmospheres, even
at high temperatures
• Resistant to corrosion caused by chlorine gas and
chlorinated media as well as many oxidizing mineral
and organic acids, sea water etc.
• Corrosion from ultrapure water
• Not to be used in a sulfur-containing atmosphere
1) Can be used to a limited extent up to 800 °C (1472 °F) for low compressive loads and in non-corrosive
media. Please contact your Hauser sales team for further information.
