Question

why do we use metals such as iron and stainless steel to make locks

Answer 1

Solution :-

When people choose locks, they are worried about the durability of locks. Usually locks are made up of those metals which do not rust. In terms of durability, stainless steel is the best material to make locks. Stainless has good strength, high corrosion resistance and no discoloration. Stainless steel has different categories. It is mainly classified into ferrite and austenite. Ferrite steel has magnetism. It is also called stainless iron. It can rust if it is used for a long time and under very poor conditions. Austenite steel cannot rust.
