The global stainless steel industry continues its upward trajectory with a notable 2.1% year-on-year growth in 2025, signaling robust demand across industrial sectors. This growth reflects increasing applications in construction, automotive, energy, and manufacturing industries worldwide, with specialized grades like austenitic SS 310 gaining significant traction in high-temperature applications.
Understanding the Growth in Stainless Steel Demand
The 2.1% production increase demonstrates the resilience of the stainless steel market despite global economic uncertainties. India, as one of the world's largest stainless steel producers and consumers, has played a pivotal role in this growth, with cities like Mumbai emerging as major hubs for specialized stainless steel manufacturing and supply.
Spotlight on Austenitic SS 310: A High-Performance Grade
Among various stainless steel grades, austenitic SS 310 has witnessed increased demand due to its exceptional heat resistance and oxidation properties.
Chemical Composition of SS 310 Grade
The composition of SS 310 is carefully balanced to deliver superior high-temperature performance:
Chemical composition of SS 310 grade:
- Carbon (C): 0.25% max
- Chromium (Cr): 24.0-26.0%
- Nickel (Ni): 19.0-22.0%
- Manganese (Mn): 2.0% max
- Silicon (Si): 1.5% max
- Phosphorus (P): 0.045% max
- Sulfur (S): 0.030% max
- Iron (Fe): Balance
This unique composition SS 310 provides excellent resistance to oxidation and scaling at temperatures up to 1150°C (2100°F).
Physical Properties: Density of SS 310 Steel
The density of SS 310 steel is approximately 7.98 g/cm³ (0.289 lb/in³), which is similar to other austenitic stainless steel grades but with enhanced structural stability at elevated temperatures.
SS 310 vs. Other Grades: Key Comparisons
Comparison of SS 304 and SS 310 Material Properties
When evaluating the comparison of SS 304 and SS 310 material properties, several critical differences emerge:

The higher chromium and nickel content in SS 310 provides substantially better heat resistance.
Difference Between SS 309 and 310
The difference between SS 309 and 310 primarily lies in their nickel content and maximum operating temperatures:
- SS 309: Contains 12-15% nickel; suitable for temperatures up to 1040°C
- SS 310: Contains 19-22% nickel; withstands temperatures up to 1150°C
How to Confirm 310 SS Material
How to confirm 310 SS material authenticity is crucial for quality assurance:
- Chemical Analysis: Conduct spectroscopic analysis to verify composition
- Heat Treatment Response: SS 310 cannot be hardened by heat treatment
- Magnetic Testing: Austenitic SS 310 is generally non-magnetic
- Mill Test Certificates: Request MTCs from manufacturers
- Positive Material Identification (PMI): X-ray fluorescence testing
Market Pricing Trends
Price of SS 304 vs 310
The price of SS 304 vs 310 shows significant variation due to higher alloying content. SS 310 typically costs 40-60% more than SS 304. The price of SS 310 in India varies by city, quantity, and supplier.
Price of SS 304 and 310 2mm Thick Plates
The price of ss 304 and 310 2mm thick plates (approximate ranges as of 2025):
- SS 304 (2mm plate): ₹180-220 per kg
- SS 310 (2mm plate): ₹280-350 per kg
