Composition of 301 Stainless Steel Strip
Type 301 (UNS 30100) stainless steel is part of the austenitic
group. It’s an alloy containing chromium and nickel.
Type 301 has a chromium content of 16.0-18.0% and a nickel content
of 8.0-10.0%. Chromium is what makes stainless steel more resistant
to rust. 301 stainless steel has a lower nickel content and a
higher carbon content than other types of stainless steel.
Composition of 301Si Stainless Steel
If your application needs high ductility at extra hard tempers,
Type 301Si(UNS 301116) is a good choice. 301Si has higher silicon
than traditional 301 stainless steel.
Standard 301 has a silicon content of no more than 1.0. The silicon
content of Type 301Si is 1.0-1.35.
The additional silicon gives you good ductility at a higher tensile
strength. Yield strength is less limited than with traditional 301.
It provides more formability with less cracking.
Tensile on 301si is typically 270k min but available in higher
ranges.
Edge Condition
Providing a deburred or round edge increases the uniformity of the
spring and reduces the chance of injury. Deburring the edges
improves the shape of the strip. It has less camber and less wave.
It is also noted by spring manufacturers that the edge can
positively impact the performance and cycle life of the constant
force spring.
Corrosion Resistance
Even with its higher carbon and lower nickel content, Type 301 is
very resistant to corrosion. It resists corrosion from factors
including atmospheric conditions, food, and road de-icing salt.
Corrosion in austenitic stainless steels is usually the result of
chromium carbide precipitation.
Cold working followed by annealing creates the best corrosion
resistance. A second annealing process dissolves chromium carbides and removes discoloration. This restores its corrosion resistance
at weld or laser-cut edges.
Toughness and Fatigue Limit
Type 301 stainless steel maintains its toughness even after cold
rolling to a high tensile strength. The Charpy impact test is a
standardized high strain-rate test that measures toughness. At room
temperature, annealed 301 stainless steel strip has Charpy V-notch
energy absorption values greater than 100 feet per pound.
Fatigue is a combination of elastic deflection and plastic
deflection. Elastic deflection is the movement and returning to
shape of a spring after a load is placed on it and then removed.
Plastic deflection describes how much a spring changes its shape
permanently after it receives a load.
Materials with higher fatigue resistance make springs that last
longer. Higher fatigue resistance also helps the spring handle a
greater load.
The fatigue or endurance limit in bending for annealed austenitic
stainless steels like Type 301 is around half of the tensile
strength.
