They can only be sterilized few dozens of times, as the chrome pla- ting used to avoid rust will deteriora- te and chip off with time, contamina- ting the process Materials and finishing used in their production enables sterilizing them thousands of times
Avoiding premature rust of parts by particle contamination Using tools on Stainless Steel compo- nents such as screws, nuts, washers, pipes, bars, etc. Ship building

Aeronautics
Marine applications
Power
Chemical Industries
Carbon steel tools can leave small particles on stainless steel compo- nents, which will get contaminated, and make them rust Stainless steel tools will not con- taminate other SS components and thus not make them get rus- ted
Increasing tool lifetime Corrosive environ ments Naval ( vessels /ship maintenance)
Subaquatic
Offshore (Oil & Gas/ Wind Power…)

Chemical industries
Humid environments
Wet processing
Water desalination
Salt production

Carbon steel tools, even when they are chrome plated, will rust quickly in highly corrosive areas, leaving them unusable and having to repla ce them frequently Stainless steel is a low carbon steel enriched with above 10% chromium, which allows the formation of an invisible chromium oxide layer that protects the core from rusting.  Even when the layer is damaged chemically or mechanically, the oxygen of the environment will repair the layer again


As with carbon steels, there are dozens of different stainless steels, each of them presenting different properties for different applications. Some are more resistant to rust, some other are stronger, some harder…But non of them is best in all properties. EGA Master has chosen AISI 420 Stainless steel for the manufacturing its tools, as it combines optimally different properties required for manufacturing and use of stainless steel tools:

Hardness 38-48HRc
Tensile Strength

≥635 N/mm²


PROPERTIES APLICATION & BENEFITS
Avoiding contamination No iron or chrome-nickel contamination
Sterilization Thousands of sterilizing processes
Durability Combination of hardness, resistance and antirust protection makes it most durable
Cost Being a mass production alloy together with having good manufacturing properties makes it most cost effective for tool manufacturing


MAT: AISI 420
Composition C

In EGA Master we are sure that prevention is the most effective cure not only for increased safety, but also from an cost effective point of view. Eliminating the risk of ferrous transfer is a key factor for increasing profitability on the long term, while keeping processes, and people, safe.

CAUTION

These tools are not classified as non-magnetic but tools made of martensitic – ferromagnetic stainless steel whose magnetic permeability is much higher than the unit.
