Combined resistance to corrosion, frictional wear and temperature. Resistant to seawater and dilute organic acids. The addition of nitrogen or even vanadium, tungsten and cobalt will increase wear performance. Applications: anti-corrosion surfacing or buffer layer before martensitic stainless steel hardfacing; for example: continuous casting rolls, valve seats, shafts, pump bodies and rotors. u u u u u u u u u u u u u u u u u Alloy depositing a 13% chromium martensitic stainless steel. Resistant to wear from friction, erosion, corrosion and thermal fatigue. Can be polished. Applications: continuous casting rolls, tooling for moulded glass, valve seats, impellers. u u u u u Hard martensitic stainless steel with 13% chromium and high carbon content. Resists frictional wear. Applications: mechanical components suffering atmospheric corrosion, rolling mill guides, static brakes for railway marshalling yards. u u u u u u Alloy depositing a 13% chromium ferritic-martensitic stainless steel. CHROMECORE 414MM - addition of nickel and molybdenum. Homogeneous deposit structure with controlled ferrite content. Designed to resist metal-to-metal wear, corrosion, friction and thermal fatigue. The addition of nitrogen or even vanadium, tungsten and cobalt will increase wear performance. Applications: continuous casting rolls, hot-rolling mills, steam turbines, valve seats. u u u u u u u u u u u u u u u u u u u u u u u u u Nitrogen-alloyed 414 martensitic stainless steel, strengthened with niobium, vanadium and rare earth elements for resistance to tempering, creeping, oxidation and corrosion. The addition of rare earth elements improves corrosion resistant properties, as well as mechanical properties. Applications: continuous casting rolls, hot-rolling mills, steam turbines, valve seats. u u u u u Alloy depositing a 13% chromium ferritic-martensitic stainless steel with addition of nickel and molybdenum. High hardness due to the higher carbon content. Resistant to friction, galling, erosion, corrosion and thermal fatigue. Applications: continuous casting rolls, particularly on the straightening and horizontal zone. Back to contents page
