Alloy 303Se alloy is a free-machining stainless steel specifically designed to exhibit improved machinability. It is a non-magnetic austenitic stainless steel which is not hardenable by heat treatment. Selenium replaces sulfur to produce the free-machining characteristics and has somewhat improved formability over 303. The good mechanical and corrosion-resistant properties of the lower-sulfur grade are retained to the extent possible.

Striping processing, commonly known as “slitting “, refers to the winding of a metal coil by unwinding, slitting, leveling, winding, and processing into a desired width. Slitting processing is a basic metal processing technology that combines high-quality equipment with skilled craftsmanship. it can be obtained with strict tolerance, perfect surface control , safe packaging as well as fine transportation.
