The melting point of stainless steel is influenced by its alloy composition. Chromium, nickel, molybdenum, and carbon content play a significant role in defining the temperature at which the material melts. Stainless steels typically have melting points ranging from 1,370°C to 1,530°C (2,498°F to 2,786°F), with variations across grades.
Here is a breakdown of melting points for popular stainless steel grades, helping you select the right material for high-temperature applications.
| Stainless Steel Grade | Melting Point (°C) | Melting Point (°F) | Key Properties |
|---|---|---|---|
| 304 | 1,400 – 1,450 | 2,552 – 2,642 | High corrosion resistance, versatility |
| 304L | 1,400 – 1,450 | 2,552 – 2,642 | Low carbon, enhanced weldability |
| 316 | 1,375 – 1,400 | 2,507 – 2,552 | Superior corrosion resistance with molybdenum |
| 316L | 1,375 – 1,400 | 2,507 – 2,552 | Low carbon, excellent resistance in chlorides |
| 310S | 1,400 – 1,450 | 2,552 – 2,642 | High-temperature oxidation resistance |
| 321 | 1,400 – 1,450 | 2,552 – 2,642 | Titanium stabilized, resistant to intergranular corrosion |
| 410 | 1,480 – 1,530 | 2,696 – 2,786 | High strength, moderate corrosion resistance |
| 430 | 1,490 – 1,530 | 2,714 – 2,786 | Good formability, corrosion resistance |
| 2205 Duplex | 1,350 – 1,400 | 2,462 – 2,552 | High strength, chloride resistance |
The melting point of stainless steel is a crucial factor in selecting materials for industries that involve extreme heat. In high-temperature applications, such as furnaces, heat exchangers, and kilns, materials must withstand prolonged exposure to heat without deforming or melting. Stainless steel grades like 310S, with its higher melting point and oxidation resistance, are specifically designed for such applications. Conversely, lower melting point grades may be suitable for applications that do not reach extreme temperatures.
Several factors influence the melting point of stainless steel:
| Industry | Application Examples | Recommended Grades |
|---|---|---|
| Aerospace | Engine components, heat shields | 310S, 321 |
| Chemical Processing | Reactors, distillation columns | 316, 316L |
| Automotive | Exhaust systems, catalytic converters | 304, 409, 430 |
| Power Generation | Boilers, heat exchangers, furnace parts | 304, 310S, 316 |
| Construction | Structural supports in high-temperature areas | 304, 316, 321 |
High-temperature stainless steel grades are vital in industries that demand performance in challenging environments, from aerospace to chemical processing.
