These materials combine excellent conduc-

This treatment reduces internal stress due to

Every WAGO clamping spring made of
high-quality, accurately tested austenitic
chrome nickel steel (CrNi) with high tensile
strength, which boasts proven corrosion
resistance through long-term usage.
In certain product lines, the clamping springs
are thermally treated temperatures
between 350°C (662°F) and 420°C (788°F)
after production.
At the clamping unit, the conductor is
embedded into the soft tin layer via high con-
tact pressure.g.
WAGO only accepts deliveries chrome
nickel spring steel against certificates of

have been performed.5%.
The thick tin layer also ensures good solder-
