IS 4454 specifies stainless steel wire for springs where corrosion resistance is needed. Covers austenitic (18-8 type) and martensitic grades. Used for springs in food processing, marine, medical, and chemical environments.
Specification for stainless steel wire for mechanical springs, covering grades, dimensions, mechanical properties, and testing.
Key Values
Grade 1 (austenitic) tensile (1mm)1600-1900 MPa
Grade 1 composition18% Cr, 8% Ni (Type 302)
Practical Notes
! Use IS 4454 instead of IS 1538 (carbon steel) when springs are exposed to corrosion, moisture, or chemicals.
! Austenitic grade (Type 302/304) is non-magnetic and most commonly used for corrosion-resistant springs.
! Stainless spring wire costs 3-5x more than carbon spring wire — use only where corrosion resistance justifies the cost.
