Stainless Steel Properties
Stainless Steel Alloys: An Overview
Stainless Steel Alloys: Discover the Strength, Corrosion Resistance, and Unmatched Versatility for Your Manufacturing Needs
Stainless steel alloys are the primary choice for many manufacturers seeking durability, outstanding corrosion resistance, high strength, and versatility in their materials. There is a wide range of Stainless Steel alloys for manufacturers to choose from, depending on the application and end-use requirements, so it is beneficial to understand the difference between grades.
Â
Key Features and Benefits
- Strength and Durability:Â Stainless Steel alloys are known for their high strength and durability, making them an ideal solution for various applications and industries.
- Corrosion Resistance:Â The addition of chromium in stainless steel alloys forms a protective oxide layer, giving them outstanding corrosion and oxidation resistance.
- Formability:Â Stainless Steel alloys offer excellent formability, allowing manufacturers to create intricate shapes and components with ease.
- Weldability:Â These alloys have good welding capabilities, making them ideal for applications that require complex assemblies and fabrications.
- Versatility:Â With over 38 unique stainless steel alloys available, manufacturers can choose the perfect material for their specific application and end-use requirements.Â
Understanding Stainless Steel Alloys
Stainless Steel alloys can be grouped into five main categories: Austenitic, Ferritic, Martensitic, Duplex, and Precipitation Hardening (PH). Each type offers different properties and benefits, making them suitable for various applications.
Â
All stainless steel grades contain chromium, offering outstanding corrosion and oxidation resistance. Adding chromium helps form the complex oxide surface, which gives Stainless Steel its protective corrosion resistance. However, some stainless steel grades can equally possess other exceptional properties owing to variations in their composition. These subtle composition changes created by using different alloying elements alter the microstructures within the material resulting in a wide range of versatile mechanical properties. While there are many precision alloys for manufacturers to choose from, stainless steel alloys form one of the largest groups of materials; therefore, it is beneficial to categorise them by microstructure.
Â
Though Austenitic grades are the most popular choice, Knight Group supplies all five types of precision stainless steel alloys in precision strip and wire, ensuring you can find the perfect material for your manufacturing needs.

Summary Table: Understanding the types of Stainless Steel Alloys available
| Material | Grades Supplied | Main features | Advantages | Disadvantages |
|---|---|---|---|---|
| Austenitics | 205 | · Non magnetic* · Low Carbon · Main alloying element is chromium typically 16-20% · Nickel typically 7-13% | · Strengthens significantly during cold working · Good weldability · High strength and ductility | · Cannot be hardened by heat treatment · Low stress corrosion cracking resistance |
| Heat Resisting Austenitcs | 301, 302, 303, 304L, 304, 305, 320, 321, 347, | |||
| Super Austenitics | 316, 316L, 316LVM, 316Ti, 904L | |||
| Ferritics | 409, 410S, 430, 430L, 430Ti (439), 441, 444 | · Magnetic · Low Carbon · Main alloying element is chromium, typically 10.5-17% | · Good formability · Low cost · Good stress corrosion cracking resistance · Moderate ductility | · Limited corrosion resistance · Cannot be hardened by heat treatment |
| Martensitics | 410, 420, 431 | · Can be magnetic or non magnetic · Low Carbon · Main alloying element is chromium typically 12 to 15% molybdenum (0.2-1%) | Hardened by quenching and tempered to give improved toughness and ductility | · Less resistant to corrosion compared to Austenitic and Ferritic grades · Limited formability and welding capabilities |
| Precipitation hardening | 17/4PH, 17/7PH | Contains Aluminium or Copper | High work hardening rates / Very high strengths / Better corrosion resistance compared to martensitics | · Limited availability · Lower corrosion resistance formability and weldability compared to austenitics |
| Duplex | 309, 310 | · Magnetic · Low Carbon · Combined Austenitic-Ferritic structure · Chromium typically 21-26% · Nickel typically 3.5-6.5% | · Superior tensile strength in annealed condition · Good corrosion and pitting resistance · Lighter weight · Lower cost due to lower nickel content | · Cannot be hardened by heat treatment but offers higher annealed strength levels than Ferritic or Austenitic grades · Restricted application temperature range when compared to Austenitics |
* cold working of the less alloyed grades will induce structural changes leading to increased levels of magnetism.
