Stainless steel bars are essential in modern infrastructure and manufacturing. From building frameworks to precision-engineered parts, their strength and corrosion resistance make them indispensable. Among different grades, the 202 stainless steel bar has become a popular choice due to its combination of durability, affordability, and versatility.
If you are an engineer, project manager, or procurement professional, understanding the value of SS 202 bars can help you make smarter buying decisions. This guide explains everything about 202 stainless steel bars—from features and applications to how to choose the right supplier.
What is 202 Stainless Steel Bar?
202 stainless steel bar belongs to the austenitic family of stainless steels. It was designed as an economical alternative to 304 stainless steel. By reducing nickel content and increasing manganese, the 202 grade maintains strength and toughness while lowering production costs.
This makes the stainless steel 202 bar suitable for a wide range of uses where high corrosion resistance is not the top priority, but durability and affordability are.
Composition of 202 Stainless Steel Bar
The chemical composition defines the behavior of SS 202 bars in different environments.
- Chromium (17–19%) – Improves corrosion resistance
- Nickel (4–6%) – Provides toughness
- Manganese (7.5–10%) – Reduces cost by replacing part of the nickel
- Carbon (≤0.15%) – Enhances hardness
- Silicon (≤1%) – Improves oxidation resistance
- Nitrogen (≤0.25%) – Adds strength
This combination allows 202 stainless steel bars to withstand mechanical loads while being more cost-effective than higher nickel grades.
Mechanical Properties of 202 Stainless Steel Bar
The mechanical performance of SS 202 bars makes them suitable for heavy-duty applications.
- Tensile Strength: ≥515 MPa
- Yield Strength: ≥275 MPa
- Elongation: ~40%
- Hardness: ≤95 HRB
These figures highlight the balance of strength and ductility in the 202 stainless steel round bar.
Why Choose 202 Stainless Steel Bar?
Buyers often compare multiple stainless steel grades before making a decision. The 202 SS bar stands out for several reasons:
- Cost-Effective Solution – Less expensive than 304 and 316 grades.
- Durability – Offers long service life under moderate conditions.
- Strength – High tensile and yield strength.
- Fabrication Ease – Easy to machine, cut, and weld.
- Availability – Widely stocked by 202 stainless steel bar suppliers in India.
- Eco-Friendly – 100% recyclable without losing quality.
Types of 202 Stainless Steel Bars
When buying stainless steel bars, knowing the available forms helps in selecting the right one for your project.
- Round Bar – Common for shafts, fasteners, and machine parts.
- Square Bar – Used in structural and architectural applications.
- Flat Bar – Suitable for brackets, reinforcements, and support systems.
- Hex Bar – Ideal for bolts, nuts, and precision-engineered parts.
- Bright Bar – Provides a polished surface, used in decorative items.
- Forged Bar – Stronger option for machinery and heavy-duty use.
Applications of 202 Stainless Steel Bar
The 202 SS bar finds applications in multiple industries:
Construction Industry

Comparison: 202 Stainless Steel Bar vs 304 Stainless Steel Bar
| Feature | 202 Stainless Steel Bar | 304 Stainless Steel Bar |
|---|---|---|
| Nickel Content | 4 – 6% | 8 – 10.5% |
| Manganese Content | 7.5 – 10% | ≤ 2% |
| Corrosion Resistance | Good in mild conditions | Excellent in harsh environments |
| Cost | More affordable | More expensive |
| Applications | Construction, automotive | Food, chemical, marine |
This shows that 202 stainless steel bars are best for cost-sensitive projects, while 304 bars are better for high-corrosion environments.
Buying Guide: How to Choose the Right 202 Stainless Steel Bar Supplier
