347 Stainless steel sheet is an alloy of iron, carbon and chromium. Because it does not contain nickel, it is a nickel-sparing stainless steel, also known as stainless steel. stainless steels have normal magnetic properties due to their martensitic structure and the presence of iron. stainless steels are highly resistant to high temperature oxidation and have further improved physical and mechanical properties compared to carbon steel. Most  stainless steels can be heat treated. Currently  stainless steels are used in a wide range of industries such as automotive exhausts, lifts, washing machine inner tubes, kitchenware, home appliances, medical equipment, water heaters, roof panels, curtain walls and power plant equipment.
