Stainless Steel 310 Pipe Price
Stainless steel 310 pipe is priced at approximately ₹700-900/kg in India for standard sizes (SCH 40, seamless). Prices on the international market range from $8 to $15 per kilogram, depending on the outer diameter, wall thickness, and finish.
SS 310 pipe costs roughly 30–50% more than SS 304 and 15–25% more than SS 316 due to higher chromium and nickel content. Final pricing depends on manufacturing type, surface finish, and quantity ordered. Contact Sachiya Steel International for a competitive quotation.
Chemical Composition of Stainless Steel 310 Pipe
The table below lists the chemical composition of TP 310 (UNS S31000) pipe per ASME ASTM A312/SA312.
With an iron balance, this high-alloy composition contains 24.0–26.0% chromium and 19.0–22.0% nickel. It maintains minimal impurities, with a maximum of 1.50% silicon and 0.25% carbon.
Mechanical Properties of SS 310 Pipe
TP 310 pipe meets these minimum mechanical property requirements per ASTM A312/ASME SA312.
This material has a minimum tensile strength of 75 ksi (515 MPa), a minimum yield strength of 30 ksi (205 MPa), and a minimum elongation of 35%. One of these strengths is much higher than the other.
| Property | Imperial | Metric |
|---|---|---|
| Tensile Strength (min) | 75 ksi | 515 MPa |
| Yield Strength, 0.2% Offset (min) | 30 ksi | 205 MPa |
| Elongation (min) | 35% | 35% |

Stainless Steel 310 Pipe Industrial Applications
Industries use alloy 310 conduit: chemical processing, power generation, and heat treatment. In these industries, it is important that the material can resist oxidation at temperatures above 1000°C.
Heat Treatment & Furnace Industry
SS 310 pipe used in radiant tubes, muffle furnaces, and kiln linings for high-temperature carburising resistance.
Chemical & Petrochemical Processing
Essential for reactor piping, transfer lines, and catalyst systems due to superior oxidation resistance.
Power Generation & Boiler Systems
310 stainless steel pipe is applied in superheater tubing, boiler baffles, and exhaust ducting for high-temperature creep strength.
SS 310 vs 310S Stainless Steel Pipe Comparison
This comparison assists engineers and customers in selecting the appropriate high-temperature grade depending on welding specifications and operating temperatures. Grade 310 has better creep strength for heat that stays above 1000°C for a long time. Low-carbon 310S performs better in welded systems because it effectively prevents intergranular corrosion during the common cycles of heating and cooling.
| Feature | Stainless Steel 310 | Stainless Steel 310S |
|---|---|---|
| UNS Designation | UNS S31000 | UNS S31008 |
| Carbon Content (Max) | 0.25% | 0.08% |
| Creep Strength | Higher in extreme heat | Slightly Lower |
| Welding Risk | Higher risk of sensitisation | Reduced carbide precipitation |
| Max Service Temp | Continuous above 1000°C | Better for cyclic heating |
| Best Application | High-strength furnace parts | Welded piping & fabrications |
