Stainless Steel 202 Round Bars

What is Stainless Steel 202 Round Bar?

Stainless Steel 202 is an austenitic chromium-nickel-manganese stainless steel grade. It is part of the 200 series stainless steels developed to reduce nickel consumption by replacing part of it with manganese and nitrogen. This makes SS 202 more economical compared to traditional 300 series grades while still maintaining good corrosion resistance and mechanical properties.

SS 202 Round Bars are solid cylindrical stainless steel bars available in various diameters and finishes. These bars are used for machining components, fasteners, shafts, structural parts, and general engineering applications.

Compared to SS 201, SS 202 offers slightly better corrosion resistance and improved toughness due to higher chromium and nickel content.


Chemical Composition of SS 202 Round Bars (%)

  • Chromium (Cr): 17.00 – 19.00
  • Nickel (Ni): 4.00 – 6.00
  • Manganese (Mn): 7.50 – 10.00
  • Carbon (C): ≤ 0.15
  • Nitrogen (N): ≤ 0.25
  • Silicon (Si): ≤ 1.00
  • Phosphorus (P): ≤ 0.060
  • Sulfur (S): ≤ 0.030
  • Iron (Fe): Balance

Mechanical Properties

  • Tensile Strength: ≥ 520 MPa
  • Yield Strength: ≥ 275 MPa
  • Elongation: ≥ 40%
  • Hardness: ≤ 100 HRB

Physical Properties

  • Density: 7.80 g/cm³
  • Melting Range: 1400 – 1450°C
  • Modulus of Elasticity: 200 GPa
  • Thermal Conductivity: 15.5 W/m·K
  • Electrical Resistivity: 730 nΩ·m

Corrosion Resistance of SS 202 Round Bars

Stainless Steel 202 provides good resistance to:

  • Atmospheric corrosion
  • Mild industrial environments
  • Organic chemicals
  • Food processing environments (non-marine)

However, SS 202 is not recommended for:

  • Marine environments
  • High chloride exposure
  • Strong acidic solutions
  • Highly corrosive chemical plants

For such applications, higher grades like 304 or 202 are preferred.


Heat Treatment of SS 202

SS 202 cannot be hardened by conventional heat treatment. However, it can be:

Annealed at:

1010°C to 1093°C.Followed by rapid cooling (water quenching) to restore ductility and relieve stresses.Cold working is the primary method used to increase strength and hardness.


Machinability of SS 202 Round Bars

SS 202 offers moderate machinability compared to 300 series grades.

Machining Recommendations:

  • Use sharp carbide tools
  • Maintain controlled cutting speeds
  • Use adequate coolant
  • Avoid dwell time to reduce work hardening

Because SS 202 work-hardens quickly, proper machining techniques improve tool life and surface finish.


Weldability of Stainless Steel 202

SS 202 can be welded using standard welding processes:

  • TIG (GTAW)
  • MIG (GMAW)
  • Shielded Metal Arc Welding (SMAW)

Proper heat input control is essential to prevent distortion and cracking. Post-weld annealing may be performed if required.
