A world developing exponentially fast, creates increasing needs on safety and technologically advanced applications. EGA Master has developed a new range of stainless steel tools to provide solutions to some of these needs. 420 * stainless steel contributes to avoid contaminations, rusting and complying with clean room environment requirements.
(*) The stainless steel roller cabinets are made of 430 stainless steel.
Property required | Where needed | Sectors | Why not carbon steel | Why stainless steel |
---|---|---|---|---|
Zero or low tolerance to contamination and particles | Sterile production in critical environments | Laboratories | They can only be sterilized few dozens of times, as the chrome plating used to avoid rust will deteriorate and chip off with time, contaminating 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 components such as screws, nuts, washers, pipes, bars, etc. | Ship building | Carbon steel tools can leave small particles on stainless steel components, which will get contaminated, and make them rust | Stainless steel tools will not contaminate other SS components and thus not make them get rusted |

Increasing tool lifetime | Corrosive environments | Naval ( vessels / ship maintenance) | Carbon steel tools, even when they are chrome plated, will rust quickly in highly corrosive areas, leaving them unusable and having to replace 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 420 stainless steel for the manufacturing its tools, as it combines optimally different properties required for manufacturing and use of stainless steel tools.
Hardness | 38-48 HRc |
Tensile Strength | 1200-1500 N/mm2 (MPa) |
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 |

Mn | ≤ 1,00 % | |
Si | ≤ 1,00 % | |
Cr | 12 % - 14 % |
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.
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.
