Heat Resistant Nickel Based Cobalt Alloy W.Nr. 2.4778 Rod Forging Tube
Heat-Resistant Nickel Based Cobalt Alloys W.Nr. 2.4778 Rod Forging Tube
W.Nr. 2.4778 is a heat-resistant cobalt alloy with excellent thermal shock resistance and wear resistance performance. We can supply W.Nr. 2.4778 in forms of Rods, forgings, seamless pipes, tube and so on.
Chemical Composition (%, EN 10295)
As for the wear resistance of W.Nr. 2.4778, hardly any deterioration was found after being used as a sintering bar for copper sulfide for 50 months. On the other hand, cast iron parts used till then were heavily corroded, oxidized and worn even though operations were conducted at 900, making them usable for only three and a half months.
W.Nr. 2.4778 can be welded together by arc or oxy-acetylene methods. When higher wear resistance is required, weld additionally with BISHILITE (HARDFACING ALLOYS). When welding W.Nr. 2.4778 to stainless steel or steel, MA-W welding rod can be used.
High Temperature Resistance, Thermal Shock Resistance , Wear Resistance.
Higher melting points than other cobalt based and nickel based alloys (1380 -1395 °C)
Corrosion resistant in Sparse sulfuric acid and boiling nitric acid and corrosion rapidly in hydrochloric acid
Thermco50, Co50, Umco50
