    Although stainless steel is much stronger than iron and it does not rust, it is seldom used to make large objects, the followings are the objectives:

    → Stainless steel is very heavy. Scaffolding in construction site usually use iron instead of stainless steel as stainless steel is very heavy, there will be potential risk in using it as the material.

    → Stainless steel is very expensive. If stainless steel is used to make large objects, the cost will be too high and it is undesirable.

    → There are some metals which can replace stainless steel and they may be much better than it. Such as titanium and aluminum.

    Stainless steel is light but expensive.

    Stainless steel is made from iron and chromium.

    You know, chromium (Atomic number is 24) is an expensive metal.

    It is costly to make large objects totally by stainless steel.
