According to the status of steel industry in providing key products in each country, Production of steels with high quality and reasonable price is concerned. One of the parts that play a central role in determining the price and the quality of the produced steel, are rolling section and rolling rolls which Production and maintenance costs of the rollers will have an important role in the final cost of steel production and also will be effective on the final quality of the steel produced. The rollers that use for rolling roll nowadays, are produced with SS304 stainless steel with a clad of NiCrBSi. In case of failure on the coating of the rollers, thermal spraying method and laser are used to repair them. In addition to the high amount of the repairing costs with these methods, in some cases the desirable properties are not satisfied. However, because of the presence of the wear-resistant coatings at high temperatures, there is no need of using expensive and special substrate. So, for this reason in the present work Diamalloy2001 nickel-base super alloy was applied on SS304 and St37 steel substrate. Gas Tungsten Arc Welding were used as cladding process. Welding current intensity and discharge of shielding gas were chosen as welding parameters. After cladding In order to obtain optimum conditions for applying coating on each substrate, the samples were tested with the hardness test and the dilution were calculated. The samples with highest hardness and lowest amount of dilution were selected as the optimum samples for each substrate. The morphology and chemical composition of the optimum samples were studied by using optical microscope, scanning electron microscope, X-ray diffraction analysis and EDS analysis. Because of presence of dilution, different thermal properties and chemical composition of substrates, the microstructure and types of composed phases and chemical composition of the coating matrix were changed. The results indicated that the variation of those properties that were named, affected the wear and oxidation behavior of the coatings. The wear tests wear done at tow temperature of 300 °C and 500 °C and three load of 15N, 20N and 25N. The results indicated that at 300 °C the coatings behave in the same way but at 500 °C the behavior of them were completely different. The notable point was the better wear behavior of St37-A 3 coatings in comparison with SS304-A 2 coatings that experienced lower weight loss in all load and temperature that were tested. Isothermal oxidation test were done in the 1050 °C and time duration of 260 hours. Both of the coatings had low weight change but again the St37-A 3 showed more resistance in comparison with SS304-A 2 .
