ASTM A240 AISI 441 Stainless Steel Sheet 0.4-6MM 441 Stainless Steel Data Sheet
When it comes to stainless steel, there are many different types. One such type is 441 stainless steel. 441 stainless steel has become popular due to its many uses and properties. This blog post will provide an overview of 441 stainless steel and explore its composition, mechanical properties, physical properties, and uses.
441 Stainless Steel Composition
441 stainless steel is made up of three major alloying elements: chromium (Cr), molybdenum (Mo), and titanium (Ti). Chromium helps to improve corrosion resistance and formability, while Mo helps increase strength and hardness. The addition of titanium helps improve the material’s weldability by stabilizing the austenite structure that forms during welding.
| Element | Content (%) |
| Chromium, Cr | 17.50-18.50 |
| Titanium, Ti + Niobium, Nb | 0.60 max |
| Carbon, C | 0.02 max |
| Iron, Fe | Remainder |
441 Stainless Steel Mechanical Properties
The mechanical properties of 441 stainless steel are impressive. This material boasts a yield strength of 25 ksi and a tensile strength of 75 ksi – making it one of the strongest types of stainless steel available on the market today. Its excellent ductility also makes it easy to form into various shapes with minimal effort.
| Properties | Metric | Imperial |
| Tensile strength (annealed) | 489 MPa | 70900 psi |
| Yield strength (@temperature 871 °C/ 1600 °F ) | 2.90 MPa | 421 psi |
| Modulus of elasticity | 220 GPa | 31908 ksi |
| Elongation at break (in 2″, annealed) | 35.90% | 35.90% |
| Hardness, Rockwell B (annealed) | 80 | 80 |
441 Stainless Steel Physical Properties
In terms of physical properties, 441 stainless steel is also quite impressive. It has a high melting point of 2157°C (3915°F), allowing it to be used in various high-temperature applications without fear of melting or distortion due to heat exposure. Additionally, this material has excellent corrosion resistance against oxidizing acids like sulfuric acid and reducing acids like hydrochloric acid – making it a perfect choice for use in chemical processing environments where these acids may be present.
