FIFTEEN POINTS OF STAINLESS STEEL
1. Stainless Steel is an alloy of iron and chromium with minimum 10.5 percent. 2. Chromium produces a thin layer of oxide on the surface of steel called as "passive layer". This prevents corrosion. 3. for other useful properties it also contains carbon, silicon, manganese, nikel, molybdenum. 4. stainless steel was discovered in 1913 sheffield metallurgist Harry Brearley. 5. Types of corrosion in stainless steel: Pitting Corrosion, Crevice Corrosion, General Corrosion, Stress Corrosion Cracking (SCC), Intergranular Corrosion, Galvanic Corrosion pitting Corrosion due to chlorine ion like in salt and bleach. to avoid it have to use high resistance steel to corrosion. Crevice corrosion is due to lack of oxygen on the passive layer. For this use flexible sealant or high corrosion resistant grade. General Corrosion due to certain concentrated hydrochloric Acid, Sulphuric Acid. Stress Corrosion Cracking (SCC): This corrosion normally happens in hot water tank and swimming...
