Re: Scrap Stainless

The four major types of stainless steel are:

• Austenitic – (Used for Medical equipment, containers, pipes and construction) Non Magnetic

• Ferritic – (Used for domestic appliances, boilers and indoor architecture) Magnetic

• Austenitic- Ferritic – (Used for industrial and petrol chemical applications) Magnetic

• Martensitic – (Used for Turbine blades and Knives) Magnetic

All Stainless Steel Rusts
Rust is the common name given to the reaction that occurs when any metal is in contact with oxygen (oxidisation). The effect of this reaction depends on the type of metal and will continue as long as the surface of the metal is exposed to oxygen.

Unlike mild steel and iron which form a coarse loose layer of rust which allows oxygen through, Stainless steel forms a micro layer of Chromium oxide which prevents oxygen from reaching the metal surface. This invisible to the naked eye micro layer of rust is normally very stable, and further rusting is prevented. However, if this layer is damaged by scratching or chemicals, the process of rusting will start again. It is therefore important that care is taken when cleaning stainless steel to avoid scratches and chemicals that can breakdown this very thin Chromium oxide layer.

Re: Sealed tubs

sorry, should have included PNC’s as production has moved country, only the new PNC’s have bolted tubs (not sealed)
