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.

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
AISI 316Ti/
1.4571
X6CrNiMoTi17-12-2
700 °C (1
292 °F)
1)
• Properties comparable to AISI316L
• Addition of titanium means increased
resistance to intergranular corrosion
even after welding
• Broad range of uses in the chemical,
petrochemical and oil industries as
well as in coal chemistry
• Can only be polished to a limited
extent, titanium streaks can form
Inconel600/
2.4816
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
• Resistance to corrosion caused by
chlorine gases and chlorinated media
as well as many oxidizing mineral and
organic acids, sea water etc.
• Corrosion from ultrapure water
• Not to be used in sulfur-containing
atmospheres
