To make it last for a long time
Stainless steel is an alloy primarily made of iron, chromium, nickel, and other metals that is highly resistant to corrosion. Zinc steel, on the other hand, is carbon steel coated with a layer of zinc for added protection against rust and corrosion. Stainless steel is generally more durable and has a longer lifespan compared to zinc-coated steel.
Stainless steel is an alloy of steel and chromium. The chromium is added for what is called passivation -- that is, to make passive or unreactive. When the chromium metal in stainless steel meets air, it forms a very thin layer of chromium (III) oxide. This layer is inert, impermeable to water, and extremely resistant to all forms of corrosion (since it is already oxidized). It protects the inner structure of the steel from rust cavities, since it prevents oxidation in the iron itself. Stainless steel is easily sterilized, and any harsh treatments that remove parts of the material are met with innate regeneration of the protective chromium oxide layer. These properties make it ideal for biological uses, such as eating utensils and surgical instruments, and for uses where corrosive materials are present, such as industrial process equipment that deal with acids.Though it is the chromium that makes stainless steel, there are many grades of stainless steel which many contain a few other additives. Nickel is the most widely-used one, which is used to make the metal less brittle. Most stainless steel products contain considerable amounts of nickel. Other additives are manganese, which is typically used more or less as a substitute for nickel, and molybdenum, which adds strength, thermal resistance, and corrosion resistance to the stainless steel.
Chromiun is the primary metallic element added to steel to make stainless steel.
Some examples of ferrous metals include iron, steel, and stainless steel. These metals contain iron as the primary element and possess magnetic properties. They are commonly used in construction, machinery, and automotive industries.
Stainless steel is generally more durable than zinc. Stainless steel has better resistance to corrosion, heat, and discoloration compared to zinc, which may tarnish and corrode over time. Stainless steel is also stronger and more resilient to physical damage.
why are other metals added to stainless steel
Stainless Steel must have at least 10.5-11% chromium content.
Stainless steel has low electrical conductivity compared to other metals.
Iron and chromium are the two main metals mixed in the manufacturing of stainless steel. Other metals such as nickel, manganese, and molybdenum may also be added in varying quantities to achieve specific properties in the final product.
The addition of other metals makes steel stainless.
The conductivity of stainless steel is relatively low compared to other metals, making it a poor conductor of electricity.
Steel is just a form of iron that is refined differently to iron in a blast furnace, as it is allowed to have a small amount of carbon and other alloying metals. However other forms of steel such as weathering steel and stainless steel have other metals (chromium, magnesium etc.) added to them to give them the properties that they require for their particular purpose.
Stainless steel is an alloy primarily made of iron, chromium, nickel, and other metals that is highly resistant to corrosion. Zinc steel, on the other hand, is carbon steel coated with a layer of zinc for added protection against rust and corrosion.

Stainless steel does not corrode like other metals do. because of the tannic acid in cedar and the fact that it will be outdoors stainless steel will resist corrision much better.
The benefits of stainless steel materials are that they will not rust as other steels would. Additionally, steel is a lot more common than some other metals.
stainless steel
Oversimplifying it alot: Iron + Carbon --> High Carbon Steel High Carbon Steel + Chromium & other surface alloy metals --> Stainless Steel Basically Stainless Steel is ordinary Steel with a surface Chrome Steel layer protecting it from corrosion.
