Stainless Steel

Stainless steel, with carbon percentages ranging from 0.03% to 1.2%, encompasses a diverse family of approximately 200 alloys known for their remarkable heat and corrosion resistance properties.


Its distinguishing characteristic is the high chromium content. Stainless steel typically contains a minimum of 10.5% chromium, which enhances its corrosion resistance and strength.


The chromium in the alloy creates a passive layer on oxidation upon exposure to air. This layer acts as a shield against further corrosion essentially making the alloy rustproof. This mechanism allows for retaining a spotless appearance for long periods under normal working conditions.
