We manufacture welded 310 stainless steel tube from 6mm to 63.5mm OD, 0.4mm to 2mm wall thickness, to ASTM A249 and A213 standards.
We manufacture welded 310 stainless steel tube from 6mm to 63.5mm OD, 0.4mm to 2mm wall thickness, to ASTM A249 and A213 standards. With 24-26% chromium and 19-22% nickel — significantly higher than 304 or 316 — 310 offers excellent resistance to oxidation and scaling at sustained high temperatures, making it a standard choice for heating elements and furnace components.
| Element | Value |
|---|---|
| Chromium (Cr) | 24.0–26.0 |
| Nickel (Ni) | 19.0–22.0 |
| Carbon (C) | ≤0.25 (310) / ≤0.08 (310S) |
| Manganese (Mn) | ≤2.00 |
| Silicon (Si) | ≤1.50 |
| Phosphorus (P) | ≤0.045 |
| Sulfur (S) | ≤0.030 |
| Iron (Fe) | Balance |
| Property | Value |
|---|---|
| Tensile strength | ≥515 MPa |
| Yield strength (0.2%) | ≥205 MPa |
| Elongation | ≥40% |
| Density | 7.9–8.0 g/cm³ |
Figures shown are standard reference values for this grade; exact limits are governed by the applicable ASTM/ASME specification on your order and Mill Test Certificate. See our Heating Elements & Immersion Heater Tubes page for our specific size range and finishing options for this application.
| 310 | Incoloy 800 | |
|---|---|---|
| Base | Stainless steel (Fe-Cr-Ni) | Nickel-iron-chromium alloy |
| Best for | High-temperature oxidation resistance, general high-heat service | Higher resistance to oxidation, carburization, and corrosive atmospheres |
| Cost | Generally more economical | Generally higher, reflecting nickel content |
In short: 310 is a strong, more economical choice for most high-temperature applications; Incoloy is typically stepped up to for more demanding combinations of heat and corrosive/carburizing atmosphere. See our Heating Elements page for guidance specific to your application.
