The Duplex stainless steel 2507 Perforated Metal is comprised of 25% Cr, 4% Mo and 7% Ni produced for the industrial applications that need large strength and resistance to corrosion such as in the chemical process, petrochemical and sea water devices. The Duplex stainless steel 2507 Perforated Metal offers superior resistance to chloride stress corrosion cracking, large thermal conductivity and nominal coefficient of thermal expansion. The large concentration of chromium, molybdenum and nitrogen offer superior resistance to pitting, crevice and natural corrosion.
Perforated metal is basically a sheet metal consists of perforated, embossed or slotted plates. It is basically made by puncturing the material by using a tool. The perforated metal is made of specific metal that has holes made by a die. On the base of kind of metal, the ratio of hole size to material is adjusted. We have professional and expert die and tool makers who perform the task quickly.
We offer the perforated metal in the following shapes: Circle, square, triangle, hex, oval and various other shapes. We utilize the latest tools to puncture the holes in the different shapes making the process more economical and spectacular.
