Duplex Stainless in Pulp and paper, Chemical engineering and Nuclear Energy Pulp and paper The Pulp and Paper industry is very competitive, and reducing costs a priority. In spite of it, or because of it, this industry has been one of the earliest ones to recognise the value of duplex stainless steels. For example, S32205 [...]
The Difference Between Cold Drawn and Extruded Metals Shaping metal can be a tricky process. Metal bars and rods can be formed relatively easily, into shapes such as pipes, beams and various types of channel bars are metal configurations that sometimes require special forming processes to create. Two very popular metal forming processes are extrusion [...]
WHAT IS A FERROUS METAL? There are many different categories into which metals can be placed. Some metals may be ductile, some may be brittle. Other metals could be magnetic, and some have no magnetism at all. Some types of alloys can be precipitation hardened, and others cannot. The aforementioned are important distinctions; however, when categorizing [...]
