301 stainless steel Fatigue Strength

 

301 is an austenitic stainless steel, with a tensile strength of up to 1800 Mpa, has good resistance to atmospheric corrosion, cold deformation through the processing of steel strength, hardness, and to retain adequate plastic, toughness, combined with the steel in the atmospheric conditions with good resistance to rust,

 

301 stainless steel Chemical composition:
Cr 16-18%
Ni 6-8%
C 0.15% max
Mn 2% max
Si .75% max
P 0.40% max
S .030% max

Impact Resistance:
Annealed austenitic stainless steels exhibit high resistance to impact even at low temperatures. This property, in combination with strength and fabricability, has led to their use in cryogenic applications.

 

Fatigue Strength:
The endurance limit of annealed Type 301 is 30-45 percent of the tensile strength. Cold rolling increases the endurance limit as compared with annealed material. Stress relieving increases the endurance limit of cold rolled material.
