Stainless steel is an alloy of iron with carbon and other alloy additions containing up to 2% carbon. “Stainless Steel” covers all types of stainless steels, i.e. both existing stainless steels and acid resistant steels.

Stainless steel of 1.4301 (304) quality is distinguished by:

  • good cold-processing,

  • excellent weldability,

  • excellent impact strength,

  • ductility,

  • very good corrosion resistance,
  • sufficient strength,

  • lack of magnetism

In addition to steel grade 1.4301 (304) there are other variations of austenitic steel:

  • 1.4306 (low carbon – 304L) – 18% Cr, 10% Ni,

  • 1.4307 (low carbon – 304 L) – 18% Cr, 8% Ni,

    • recommended for welding thicknesses greater than 6 mm,

  • 1.4401 (with molybdenum – 316) – to the more aggressive environments

  • 1.4404 (low-carbon Mo – 316 L),

  • 1.4571 (with titanium – 316Ti) – an alternative to 1.4404, but is unsuitable for decorative applications and polishing in the construction industry

Agents containing ingredients such as chlorine, salt, acids and bleaches must not be used for cleaning products such as stainless steel 1.4301 (304). Even low levels of these ingredients can cause permanent damage to the coating of chromium responsible for the anti-corrosion properties and ultimately leads to the formation of corrosion. Wire brushes of carbon steel, cleaning wool and steel scouring pads should not be used either, because they also significantly contribute to the formation of corrosion.

Regular maintenance of stainless steel 1.4301 (304) prevents the formation of deposits, maintains the gloss and prolongs the working life. It also facilitates the removal of spots and tarnishing. Cleaning stainless steel 1.4301 (304) should be done before the appearance of a visible layer of dirt or fingerprints, so that the effort and cost of cleaning is minimized, and the risk of permanent discoloration of the surface appearance of the steel is kept to a minimum. Appropriate, regular maintenance of stainless steel 1.4301 (304) ensures its beautiful appearance and guarantees a durable and long service life for steel products.
