Stainless Steel Welding Wire Used to Weld Machine of Food

Stainless steel is made up of a variety of elements, like: C, Si, Mn, P, S, Cr, Ni, Mo, Cu and so on. Because the content of these elements is different, there are many types stainless steel, for example: 301, 304L, 316, 316L, etc. The specific classification of stainless steel and corresponding elements content are shown in the table below. Different stainless steel has different application, so the use of stainless steel welding wire is very extensive.

Stainless steel welding wire winded on a blue basket.
Blue basket makes the package of stainless steel welding wire more colorful.
Shining stainless steel welding wire winded on a thick black plastic spool.
Spool-packaged stainless steel welding wire is cheaper for its widely use.
Stainless steel welding wire is winded into round shape.
Coil-package makes the packing of stainless steel welding wire very simple.

Main Characteristics:

  • Stable electric arc, low splashing and less smoke.
  • Less harm to the operator, environmental protection.
  • High deposition efficiency.
  • Good feeding stability.
  • Good conductivity.
  • High strength and forming better.
  • Strong acid & alkali resistance and anti-rust.
  • Both AC and DC are applicable.

Application:
Stainless steel welding wire has strong corrosion resistance, and it can resist acid and alkali, so it is very popular in welding industry.

A small bend is welded together with a small tee joint.
Stainless steel welding wire makes the seam show scaly for pretty appearance.
  • Because of the need for a single stainless construction, stainless steel welding wire is usually used for welding stainless steel parts.
  • Stainless steel welding wire can be used to weld carbon steel and 500MPa grade high strength steels, like: cars, buildings, ships, bridges and high speed welding for thin plates.
  • And it can be used for food machine welding, but other welding wires can't.
  • It also can be used in mesh weaving, soft pipe, chemical industry, electric power, petroleum refining, architecture, furniture manufacture, machine tools and so on.

Details:

  • Material: Stainless steel.
  • Diameter: 0.6-5.0mm.
  • Package: 5, 10, 15, 20kg/plastic spool, each plastic spool in a carton, cartons on wooden pallets.
