Applications

CEWELD® DUR 12U is a Stelitte 12 alloy with excellent properties against abrasion, thermal shock and corrosion in conjunction with high temperatures. It produces a high-quality hardfacing on components that are exposed to multiple stresses from erosion, corrosion, cavitation, pressure, impact, abrasion and high temperatures up to 900 ºC.

For example: sealing surfaces on fittings, valve seats and cones for combustion engines, metal-to-metal sliding surfaces, highly stressed hot work tools without thermal shock, grinding, stirring and drilling tools.

Properties

CEWELD® DUR 12U exhibits excellent welding properties and self-releasing slag. The weld metal can be machined with carbide tools and by grinding. The hardness of the weld metal decreases by around 20% at 600 °C. The weld metal is highly heat-resistant up to 900 °C. CEWELD® DUR 12U offers a low coefficient of friction and exceptional resistance to abrasion. Cavitation and erosion resistance is ten times that of 304 stainless steel. CEWELD® DUR 12U can be used to protect bearing surfaces in non-lubricated conditions due to its resistance to metal-to-metal wear. 

Hardness of the pure weld metal
Hardness at RT: 48 - 50 HRC
Hot hardness at 500 ºC: approx. 40 HRC
Hot hardness at 700 ºC: approx. 33 HRC
