All You Need To Know About Stainless Steel 316 Slitting Coils
Steel coil slitting is a method of cutting metal, where large sheet metal rolls or coils are cut with very sharp rotary blades. They are cut length-wise into the large coil to obtain straight lines, creating narrower strips. Circular blades are used as the coil runs through the slitter to make the cuts. These are referred to as “knives” and can be moved to obtain different widths. The slit parts are cut to a smaller width while keeping the length same. Before being cut, the original coils are positioned for uncoiling on an uncoiler drum, before being flattened on a ready to cut leveler ready for slitting. Stainless steel can be slit into several varying widths. Each application requires its own stainless steel coil slitting capability.
Slitting can be used equally well for both sheets and plates. Every job needs the blades to be tailored for the particular job. Precision is the name of the game when it comes to slitting steel coils.
Characteristics of SS 316 Slitting Coils:
SS 316 Slitting Coils have better overall corrosion resistant properties particularly higher resistance to pitting and crevice corrosion in chloride environments. It has excellent forming and welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields. Stainless Steel 316 Slitting Coils also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.
Excellent in a range of atmospheric environments and many corrosive media and Good oxidation resistance in intermittent service to 870 degrees C and in continuous service to 925 degrees C.
Hot & Cold Working with 316 Stainless Steel Slitting Coils:
Stainless Steel 316 Slitting Coils are worked using Solution Treatment (Annealing) – heat to 1010-1120 degrees C and cool rapidly. 316 Slit Coils cannot be hardened by thermal treatment. Heavy welded sections in SS 316 require post-weld annealing for maximum corrosion resistance. SS 316 being extremely tough and ductile, can be readily fabricated by cold working.
Applications of Stainless Steel 316 Slit Coils:
Owing to its outstanding corrosion and oxidation resistance, good mechanical properties and fabricability, SS 316 Slit Coils are used for various applications which include food preparation equipment particularly in chloride environments, laboratory benches & equipment, coastal architectural panelling, railings & trim, boat fittings, chemical containers, including for transport, heat exchangers, woven or welded screens for mining, quarrying & water filtration, exhaust manifolds, pharmaceutical equipment, chemical & petrochemical process, pulp and paper industry, etc.
