What is stainless steel ?
From the mines to the manufacturer, here’s a quick overview of how stainless steel is made
Due to its excellent corrosion resistance, high strength and attractive appearance, stainless steel sees a wide range of uses across both industrial and consumer markets.
But how does stainless steel go from a pile of scrap or refined ores to its final shape and application?
Most stainless steel starts life in a similar manner before heading off to processing. This processing—along with the exact composition of the steel alloy—determine its many characteristics.
So to understand how stainless steel is produced, we must first dive into its composition.
Stainless steel is an iron and chromium alloy.
Other common additives include:Nickel,Carbon,Manganese,Molybdenum,Nitrogen,Sulfur.Copper,Silicon
Hot Rolling
Performed at temperatures higher than the recrystallization temperature of the steel, this step helps to set the rough physical dimensions of the steel. Precise temperature control throughout the process keeps the steel soft enough to work without altering the structure.
The process uses repeated passes to adjust the dimensions of the steel slowly. In most cases, this will involve rolling through multiple mills over time to achieve the desired thickness.
