Because of excellent corrosion resistance, high strength and attractive appearance of stainless steel it is used widely both in industrial and consumer markets.Most of the stainless steel starts life in a very similar manner before heading off to processing. This processing—along with the exact composition of the steel alloy—determine its different characteristics.So to understand how stainless steel is produced, one needs to understand its composition.

Stainless steel is an alloy of iron and chromium. While stainless must contain at least 10.5% chromium, the definite components and ratios will vary based on the grade requested by the client and the intended use of the steel.

Other common additives include:

• Nickel

• Carbon

• Nitrogen

• Sulphur

• Copper

• Silicon

• Manganese

• Molybdenum

The same & definite composition of an alloy is strictly measured and assessed throughout the alloying process to ensure that the steel exhibits the required qualities.The main reason to add other metals and gasses to a stainless steel alloy include:

• Increased corrosion resistance

• High-temperature resistance

• Low-temperature resistance

• Improved weldability

• Improved formability

• Controlling magnetism

• Improved strength
