SUS310S vs SUS316: High-Temperature
Dec 03, 2025
Leave a message
In high-temperature industrial environments, selecting the appropriate stainless steel material is crucial for equipment safety and lifespan. SUS310S and SUS316 are two commonly used austenitic stainless steels, but they differ significantly in high-temperature performance, oxidation resistance, and corrosion resistance. Understanding these differences can help buyers make the optimal choice.
SUS310S vs SUS316: High-Temperature
What is SUS316 stainless steel?
SUS316 stainless steel strip is a typical grade of austenitic stainless steel, corresponding to the Chinese standard 0Cr17Ni12Mo2. It exhibits better pitting corrosion resistance than 304 stainless steel in chlorinated media and high-temperature seawater. It is mainly used in chemical equipment, marine engineering, food industry, and the manufacture of high-temperature components, and is commonly used in applications requiring high environmental adaptability, such as bolts and corrosion-resistant parts.
What is SUS310S heat-resistant stainless steel?
SUS310S stainless steel is a Japanese SUS series austenitic stainless steel, corresponding to the Cr25Ni20 grade. It is suitable for temperatures up to 1200℃, with a continuous operating temperature up to 1150℃. The heat treatment specification is solution treatment at 1030～1180℃ followed by rapid cooling, resulting in an austenitic microstructure. Product forms include pipes, plates, and bars. This material is mainly used in the petroleum, electronics, chemical, pharmaceutical, machinery manufacturing, and nuclear power industries, and is suitable for manufacturing high-temperature components such as boilers, steam turbines, and industrial furnaces.
SUS310S vs.SUS316：chemical composition
| Property | SUS310S | SUS316 |
|---|---|---|
| Material Type | Austenitic stainless steel | Austenitic stainless steel |
| Primary Use | High-temperature applications (≥1000°C) | Corrosion-resistant applications at moderate temperatures |
| Chromium (Cr) | 24–26% | 16–18% |
| Nickel (Ni) | 19–22% | 10–14% |
| Molybdenum (Mo) | 0% | 2–3% |
| Maximum Continuous Service Temp | 1100–1150°C | 870–900°C |
SUS310S vs SUS316: Mechanical Properties
| Property | SUS310S | SUS316 |
|---|---|---|
| Yield Strength (MPa) | ≥ 205 | ≥ 205 |
| Tensile Strength (MPa) | 515–700 | 515–750 |
| Elongation (%) | ≥ 40 | ≥ 40 |
| Hardness (HRB) | ≤ 90 | ≤ 95 |
| Density (g/cm³) | 7.9 | 8.0 |
SUS310S Vs SUS316: High-Temperature
For high-temperature applications, SUS310S is superior to SUS316 because of its higher chromium and nickel content, resulting in better oxidation resistance and heat resistance up to 1150°C. SUS316, containing molybdenum, is more suitable for corrosive environments, especially those containing chlorides; therefore, SUS310S is an ideal choice for applications such as furnace components and heat treatment equipment.
Oxidation Resistance (Continuous Use)
| Temperature | SUS310S | SUS316 |
|---|---|---|
| 800°C | Excellent | Good |
| 900°C | Excellent | Fair |
| 1000°C | Excellent | Not Recommended |
| 1100°C | Excellent | Not Recommended |
SS 310 vs ss316 Price
The current market price for 310 stainless steel is approximately USD 4.60–6.20 per kg, while 316 stainless steel typically ranges from USD 3.80–5.50 per kg, depending on factors like thickness, surface finish, and order quantity.
Is 304 or 310 Stainless Steel better?
310 stainless steel is superior to 304 for high-temperature applications due to its higher chromium and nickel content, which provides greater oxidation and corrosion resistance at extreme temperatures. In contrast, 304 is more ductile, more affordable, and suitable for general-purpose applications like food processing equipment and kitchenware where high heat resistance isn't the main priority.
