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.

 

Key Features and Benefits
  • Strength and Durability: Stainless Steel alloys are known for their high strength and durability, making them an ideal solution for various applications and industries.
  • Corrosion Resistance: The addition of chromium in stainless steel alloys forms a protective oxide layer, giving them outstanding corrosion and oxidation resistance.
  • Formability: Stainless Steel alloys offer excellent formability, allowing manufacturers to create intricate shapes and components with ease.
  • Weldability: These alloys have good welding capabilities, making them ideal for applications that require complex assemblies and fabrications.
  • Versatility: With over 38 unique stainless steel alloys available, manufacturers can choose the perfect material for their specific application and end-use requirements. 
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.

 

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.

 

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.

Martensitics410, 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 hardening17/4PH, 17/7PHContains Aluminium or CopperHigh work hardening rates / Very high strengths / Better corrosion resistance compared to martensitics· Limited availability · Lower corrosion resistance formability and weldability compared to austenitics
Duplex309, 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.

Other properties include good weldability and good toughness.Automotive, Chemical Processing, Transport, Paper and Pulp, Food Processingpulp and paper processing, pressure vessels, desalination, automotive trim, chemical processing, transport applications
1.4410X2CrNiMoN25–7-4-2507S 32750Duplex 2507 (1.4410) is considered a super duplex grade. As a dual-phase Austenitic-Ferritic Stainless Steel, it provides superior resistance to all corrosion with excellent protection from chloride stress corrosion cracking. It is ideally suited for service in highly corrosive conditions. It also benefits from high thermal conductivity, and a low coefficient of thermal expansion alongside high mechanical strength and good weldability. However, it is not recommended for applications requiring prolonged exposure to temperatures above 299.°C (570 °F) due to a potential reduction in toughness.Automotive, Chemical Processing, Marine, Oil and Gaspulp and paper processing, desalination, automotive trim, seawater systems, heat exchangers, oil and gas equipment, offshore platforms, chemical processing, vessels, piping, desalination
1.4662X2CrNiMoN22–5-3-(LDX) 2404S 82441Duplex Alloy (LDX) 2404 (1.4662) is an Austenitic-Ferritic Stainless Steel with high contents of Chromium and Nitrogen. This alloy offers both high corrosion resistance and a higher mechanical strength when compared to other common Duplex materials. Other properties include good fatigue resistance and good weldability, making it ideal for multiple applications.Automotive, Chemical Processing, Marine, Oil and Gas, Energy, Architecturalstructural components, piping systems, pulp and paper processing, heat exchangers, water treatment and desalination, offshore platforms, storage tanks, pressure vessels
1.4162X2CrMnNiN21–5-1-(LDX) 2101S 32101Duplex Alloy (LDX) 2101 (1.4162) is a low-alloyed, general purpose Austenitic-Ferritic Stainless Steel. It offers good general corrosion resistance, high sulphide and chloride stress corrosion resistance and overall good strength and weldability.Chemical, Water Treatment, Paper & Pulpchemical processing vessels and piping, pulp and paper mill equipment, water treatment tanks
