Stainless Steel
Stainless steel alloys are the primary choice for many manufacturers due to its versatility, with high strength, good formability and outstanding corrosion and oxidation resistance. There are wide range of Stainless Steel alloys for manufacturers to choose from, depending on application and end use requirements, so it is beneficial to understand the difference between grades.
All stainless steel grades must contain chromium offering outstanding corrosion and oxidation resistance. The addition of chromium helps to 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.
Commercial forms of stainless steel can be grouped into five main groups: Austenitic, Ferritic, Martensitic, Duplex and Precipitating Hardening (PH).
Though Austenitic grades are the most popular choice, Precision Metals EU supplies all five types of Precision Stainless Steel Alloys: Austenitic, Ferritic, Martensitic, Duplex and Precipitating Hardening (PH) in a wide range of forms.
Summary Table

| Ferritic | 409, 410S, 430, 430L, 430Ti (439), 434, 441, 444 | ● Magnetic (Due to Ferritic Structure) ● Low Carbon (Improves corrosion resistance and prevents grain growth) ● Fully Ferritic Structure (Good formability and moderate corrosion resistance) ● Main alloying element is chromium, typically 10.5-17% | ✅ Little or No Nickel (Cost-effective alternative to austenitic grades) ✅ Moderate strength (Lower than austenitic grades, but stronger than pure iron) ✅ Moderate corrosion resistance (Better in lower-chloride environments; 444 has higher resistance) ✅ Good weldability (Some grades require preheating and post-weld treatment) ✅ Good resistance to stress corrosion cracking ✅ Good formability ✅ Moderate ductility | ❌ Limited corrosion resistance ❌ Cannot be hardened by heat treatment |
| Martensitic | 410, 420, 431 | ● Most Martensitic grades are magnetic due to Martensitic Structure (410, 420, 431) ● Higher Carbon (Improves hardness and strength) ● Martensitic Structure (Allows hardening through heat treatment) ● The main alloying element is chromium, typically 12-18% ● Low Nickel (Usually <2%) ● Molybdenum (0.2-1%) | ✅ High strength and hardness ✅ Can be hardened by heat treatment (Quenching and tempering improve toughness) ✅ Tempering, when applied after quenching, can increase toughness and ductility. | ❌ Lower corrosion resistance compared to austenitic and ferritic grades ❌ Limited weldability (Requires preheating and post-weld heat treatment) ❌ Limited formability due to high hardness |
| Precipitation hardening | 17/4PH, 17/7PH | ● Magnetic (Due to Martensitic or Semi-Austenitic Structure) ● Low to Moderate Carbon (Balances strength and corrosion resistance) ● Precipitation-Hardening Structure (Combination of martensitic, semi-austenitic, or austenitic phases) ● The main alloying element is chromium, typically 15-17% ● Nickel typically 3-8% ● Additions of copper, aluminium, titanium, niobium, or molybdenum | ✅ Very high strength after ageing treatment (Higher than standard stainless steels) ✅ Better corrosion resistance than martensitic grades but lower than austenitic stainless steels ✅ Can be hardened by ageing treatment (Improves hardness and strength without severe distortion) | ❌ Limited availability (Specialty application materials) · Lower corrosion resistance formability and weldability compared to austenitics ❌ Limited weldability (Requires post-weld aging to restore properties) |
| Duplex | 2202, 2205, 2304, 2507, (LDX) 2404, (LDX) 2101 | ● Magnetic ● Low Carbon ● Balanced Austenitic-Ferritic Structure (Improves strength and corrosion resistance) ● Chromium typically 21-26% ● Nickel typically 1.5-7% | ✅ Superior tensile strength in annealed condition ✅ Good to excellent corrosion and pitting resistance ✅ Lighter weight ✅ Lower cost in lean duplex grades (2202, 2304, etc.) due to lower nickel content | ❌ Cannot be hardened by heat treatment but offers higher annealed strength levels than Ferritic or Austenitic grades. ❌ More restricted high-temperature range compared to Austenitic Stainless Steels (Tends to embrittle above 250-350°C / 480-660°F) |
* cold working of the less alloyed grades will induce structural changes leading to increased levels of magnetism.
