316L 1.4404 Stainless Steel

Type 316 stainless steel is an austenitic chromium-nickel stainless steel containing molybdenum. This addition increases the resistance against corrosion and pitting.


Type 316L is an extra-low carbon version of Type 316 stainless steel that minimizes harmful carbide precipitation due to welding.


The rolling mill, also known as a roughing mill, reduces the thickness of the steel and it is cooled by water. The material is then transferred to a cold rolling mill.


When the material arrives at the cold rolling mill it is covered in black scale and is sent through an annealing and pickling line to remove it.
