Is Brass Stronger Than Stainless Steel? Strength Data Comparison

Defining Strength Parameters

Material strength encompasses multiple properties: tensile strength (maximum stress before fracture), yield strength (stress at which permanent deformation begins), hardness (resistance to surface indentation), and fatigue strength (resistance to cyclic loading). No single number captures overall strength.

Brass Strength Data by Alloy

CW614N free-cutting brass has tensile strength of 350-400 MPa and yield strength of 250-310 MPa. CW617N forging brass achieves 380-460 MPa tensile and 170-350 MPa yield. Naval brass C46400 reaches 500+ MPa tensile.

High-tensile manganese brass can exceed 600 MPa.

Stainless Steel Strength Data

304 stainless steel has tensile strength of 515 MPa and yield strength of 205 MPa. 316L achieves 485 MPa tensile and 170 MPa yield. Notably, brass yield strength (250-310 MPa for CW614N) actually exceeds 304 stainless steel yield strength (205 MPa), meaning brass resists permanent deformation better in many cases.

Practical Strength Implications

For most precision component applications, both brass and stainless steel provide adequate strength. The deciding factors are typically machinability, conductivity, corrosion resistance, and cost rather than raw strength. Brass components manufactured by Divine Brass achieve tolerances of plus or minus 0.005 mm regardless of strength grade.
