What Is Stainless Steel?

Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the 'passive layer'. This prevents any further corrosion of the surface. Increasing the amount of Chromium gives an increased resistance to corrosion.

SS Material also contains varying amounts of Carbon, Silicon and Manganese. Other elements such as Nickel and Molybdenum may be added to impart other useful properties such as enhanced formability and increased corrosion resistance.

Is stainless steel non-magnetic?

Ferromagnetic alloys, when heated to a high temperature then it looses their ferromagnetism and become paramagnetic, they do not retain their own magnetic field but continue to be attracted to external ones. Austenitic SS have a high amount of austenite which makes them mostly non-magnetic

Stainless Steel Composition

Material Grades Supplied Description Main features Advantages Disadvantages
Austenitic Steels with Manganese 201 Austenitic SS are divided in the 200 and 300 series, with 16% to 30% chromium and 2% to 20% nickel for enhanced formability, surface quality, increased corrosion, formability and wear resistance. Austenitic SS are used for domestic, transport, industrial, and architectural products based primarily on their corrosion resistance
  • 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
Austenitics 301, 304L, 304, 305, 320, 321, 347,
Austenitic Steels with Molybdenum 316, 316L, 316Ti, 904L
Ferritics 409, 410S, 430, 430L, 430Ti (439), 441, 444 Ferritic steels is a grade of SS alloy that contains over 12% chromium. It is defined as a straight chromium non-hardenable class of SS alloys that have chromium contents range from 10.5% to 30% and a carbon content of less than 0.20%.
  • 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 Martensitic ss are characterized by high hardness and strength in the heat treated condition. We offer a range of martensitic SS alloys which contain 11 – 17% chromium with 0.15 – 0.63% carbon. Martensitic Stainless Steels grades are magnetic in both the annealed and hardened (heat treated) condition. Application Used for cookwear, cutlery, springs, scissors, industrial blades, surgical and dental instruments, screwdrivers, vehicle stampings, pliers
  • 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 Precipitation Hardening (PH) SS are classified as martensitic or semi-austenitic.Semi-austenitic grades are 17-7 PH® and PH 15-7 Mo® and Martensitic grades include 17-4 PH® and 15-5 PH®.it makes use of solid impurities or precipitates for the strengthening process.
  • 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 Duplex ss contain a mixture of ferrite and austenite in their structure, and exhibit characteristics of both phases with higher ductility and strength.Type 2205 duplex ss is a grade that offers very good pitting and uniform corrosion resistance, high resistance and high strength to stress corrosion cracking.
  • 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.
**Super Austenitics, Super Ferritic and Super Duplexes are available by request
