Product Description:
304 316 Stainless Steel Strip Ribbon Oscillate Wound Coil
Ribbon Oscillate Wound Coil (sometimes referred to as traverse winding) is the process of combining narrow slit strip to a create a coil that has significantly more linear footage than a traditional slit product. The methodology behind the creation of an oscillate is relatively simple. An oscillate wound coil is the result of welding several slit coils (also called slit-to-width coil) together, end to end, coiling them into a single coil. During this process, the coils are wound like fishing line to create a finished product that allows multiple coils to be combined into one compact coil.
Compared to normal cold rolled stainless strip, hot rolled stainless steel strip, the precision stainless steel strip need more process flow, the main important step is Tension Annealing(TA line), size tolerance control, so the precision always higher labor costs and value, also with higher technology requirement, experience, equipment. In China before 2015, most of the precision equipment was imported from Germany, Japan, Italy, and other countries, now China also can manufacture part of them with high quality and satisfying performance.
Specification of Stainless steel coil Grade
201 steel strip: belongs to chromium-nickel-manganese austenitic stainless steel with relatively low magnetic properties
301 steel strip: good ductility, used for forming products. It can also be hardened by mechanical processing. Good weldability. Abrasion resistance and fatigue strength are better than 304 stainless steel.
304 steel strip: has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping, bending, and no heat treatment hardening. Uses: tableware, cabinets, boilers, auto parts, medical appliances, building materials, food industry (use temperature -196°C-700°C), 304 stainless steel is a universal stainless steel material, anti-corrosion performance is better than 200 series stainless steel materials Be strong. The high temperature resistance is also better, which can reach 1000-1200 degrees.
304L steel strip: As a low-carbon 304 steel, in general, its corrosion resistance is similar to that of 304, but after welding or stress relief, its resistance to intergranular corrosion is excellent. It can also be used without heat treatment. Maintain good corrosion resistance.
316L steel strip: 316 stainless steel contains molybdenum and low carbon content. Its resistance to pitting corrosion in the ocean and in the chemical industry environment is much better than that of 304 stainless steel! (316L low-carbon, 316N nitrogen-containing high-strength, 316F stainless steel has high sulfur content, easy-to-cut stainless steel).
410 steel strip: belongs to martensite (high-strength chromium steel), with good wear resistance and poor corrosion resistance.
420 steel strip: “cutting tool grade” martensitic steel, similar to the earliest stainless steel such as Brinell high chromium steel. It is also used for surgical knives, which can be very bright.
430 steel strip: ferritic stainless steel, for decoration, such as car accessories. Good formability, but poor temperature resistance and corrosion resistance.
Ribbon Oscillate Wound Coil are a solution for manufacturers who strive for productivity gains and improved yields. In oscillate slitting, narrow master coils are welded (plasma or laser) end to end, then are fully planished and annealed. Coils are slit according to specifications and wound in an oscillate manner. This produces a slit strip that is up to 20 times the length of a ribbon wound coil, with bundles up to 250,000 feet in length for light gauge material. The length of the strip is limited only by the gauge of the material and OD of the oscillate slit bundle. The longer, continuous strip results in productivity improvements of up to 20% by reducing the time required for thread up, welding, and line acceleration and deceleration. Head and tail scrap is reduced during processing, resulting in maximum yield from the strip and minimal scrap handling.
