ACRONI`s wear resistant plates have been successfully used in abrasive environments for more than a quarter of a century. New investments in technology, continuous development and tight cooperation with our customers enable us to offer wider product range, high quality and short delivery terms. Our wear resistant plates are the material of choice for even the most demanding environments and applications. NICRODUR - extreme resistance to abrasive wear NICRODUR heavy plates are produced in hardness range from 220 to 540 HBW. Compared to non-alloyed structural steels, NICRODUR plates have higher durability which result in up to three times longer lifespan of your products. The unique combination of high hardness, high strength and good toughness improves bending, welding, machining properties and deformation level. NICRODUR is the material well suited for a wide variety of applications in which exposure to heavy wear by hard minerals and other abrasive materials is the case. Better performance at lower thickness S355 NICRODUR 400 NICRODUR 500 Thickness Up to three times longer lifespan of products NICRODUR 400 S355 Years NICROTER heat resistance in addition to abrasion resistance NICROTER 600 fine grain steel combines high resistance to mechanical wear, heat resistance up to 600 C, good weldability and machining. X 12 increasing hardness with exposure to wear The virtue of high manganese steel X12 (Hadfield steel, X120Mn12) is high wear resistance and work-hardnening effect on steel structure. With exposure to wear, hardness can be increased by three times compared to delivered condition. More than just steel higher efficiency through SIJ welding solutions Inside SIJ group we have developed special welding consumables to be used when welding Acroni's steel. Long experience in the field of welding and expertise knowledge enables us to offer more efficient welding solutions, that can increase welding performance and essentially reduce the costs of production by our clients.

When welding thin plates preheating is not necessary. Preheating is recommended: At outside temperatures below 5 C, Thicknesses above 20mm for NICRODUR 250 and 300 plates, Thicknesses above 8 mm for NICRODUR 400 and 500 plates. In this cases recommended temperature of preheating during infusions should not exceed 200 C. Exceeding the temperature over 200 C is not recommended as this can cause reduction of hardness. Welding should be performed immediately after the welding edges are finished, to avoid contamination. Coated electrodes must be dried before welding. By repair welding and joint welding sharp edges should be avoided, and the first layer of weld filler material should be in thinner dimensions, to assure as low as possible energy intake. * All welding instructions are reccomendations only. 10

PERFORMANCE and DURABILITY in PERFECT BALANCE Stanko Ravlan, Production Manager, Ravne Knives. Industrial knives made of Acroni wear resistant steel Where extreme wear on knives and other components is required, choice of appropriate material is crucial. ACRONI's Nicrodur, viewed from the perspective of mechanical treatment, can be easily operated. Nicrodur excellent plate flatness and narrow tolerances allow us to omit surface treatment for some types of industrial knives and wear parts. We save time and money. According to our measurments the lifetime of parts, produced using Nicrodur and Nicroter is up to three times longer in comparison to other steels. To avoid abrasive wear on industrial knives and wear parts, we recommend welding on most exposed parts. Using Acroni's wear resistant plates enables us to boost the performance of our clients.«hammers (Nicrodur 500 and Nicroter 600) Shredder knives (Nicroter 600) Screens (Nicrodur 450, Nicrodur 500) Various wear parts knife holders, wear plates (Nicrodur 450, Nicrodur 500). 11
