Stainless Steel 317L Coil
Stainless Steel 317L Coil is a low carbon version of grade 317 stainless steel, designed to offer improved corrosion resistance, especially against strong acids such as sulfuric acid and chloride environments. The lower carbon content in 317L enhances its weldability and reduces the risk of intergranular corrosion after welding or heat treatment. This alloy is rich in chromium, nickel, and molybdenum, providing superior strength and excellent resistance to pitting, crevice corrosion, and general chemical attacks. It is widely used in harsh industrial environments requiring reliable and durable materials.
Uses of Stainless Steel 317L Coil
Chemical Processing Industry: Ideal for tanks, piping, and heat exchangers dealing with aggressive chemicals.
******ceuticals: Used in equipment where purity and corrosion resistance are essential.
Pulp and Paper Industry: Suitable for bleaching plants and digesters.
Marine Applications: Performs well in saltwater and chloride-rich conditions.
Food and Beverage Industry: Utilized in clean-in-place systems and food processing equipment.
Pollution Control Equipment: Used in flue gas scrubbers and waste treatment systems.
