Selectarc Co6
CEWELD® DUR 6U zeigt ausgezeichnete Schweißeigenschaften und selbstablösende Schlacke. Das Schweißgut kann mit Hartmetallwerkzeugen und durch Schleifen bearbeitet werden. Die Härte des Schweißguts nimmt bei 300 °C um 16 % und bei 600 °C um etwa 30 % ab. Das Schweißgut ist hochhitzebeständig bis zu 900 °C.
Härte des reinen Schweißgutes: 40 – 42 HRC
Warmhärte bei 500 ºC: ca. 30 HRC
Warmhärte bei 700 ºC: ca. 160 HB

Outstanding alloy against abrasion, thermo-shock and corrosion combined with high temperatures. The weld deposit can be machined with tungsten tool tips and by grinding. The hardness of the weld deposit will degrees 16% at 300°C and about 30% at 600°C. The weld deposit is high heat resistant up to 900°C. DUR 6 offers a low coefficient of friction of 0.12 and exceptional resistance to galling. It has cavitation-erosion resistance ten times that of 304 stainless steel, DUR 6 can be used to protect bearing surfaces in non-lubricating conditions due to its resistance to metal-to-metal wear.
