303 SE Stainless Steel Coil, Strip, Foils UNS S30323 Astm A582
overview
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.

Coil Slitting Mill Capability :
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.
- Max thickness: 18 mm
- Min thickness: 0.1 mm
- Max width: 2150 mm
- Min width: 8 mm
- Width tolerance: 0 – 0.1 mm
- Burr: T<1mm: ≤0.05mm; T≥1mm: ≤5%T
