Jan 05, 2014 · The studies concluded that Hardox 450 + 40 wt % FeB composite coating was the most appropriate combination in terms of hardness and wear performance. Microstructure and wear properties of AISI 1020 steel surface modified by HARDOX 450 and FeB powder mixture SpringerLink

be used for Hardox 400 and 450 in the thickness range 0.7 6.0 mm. Low alloyed consu mables result in higher hardness of the weld metal and thus reduced wear rate of the weld metal.

Metallographic study of non homogenous armour impacted by armour piercing incendiary ammunition. In Fig. 9, Hardox 450 steel microstructure is shown it consists from tempered lathe martensite. Microstructures before and after impact, 10 mm and near fracture surface microstructure, are similar. The same is noticed for 50CrV4 steel

This FORA 400, Hardox ® 400 is a water quenched martensitic steel, with a typical hardness of 400HB (42.5 HRC), constituting a real answer to abrasive wear. Thanks to its toughness, its elevated hardness, its high yield strength, FORA 400 can be used wherever resistance to wear by sliding or by moderate impacts is required.

In the article, the structure and change in hardness of the welded Hardox 400 and Hardox 500 steels have been presented. It has been shown that structures of lower wear resistance are being created as a result of welding those materials in the as delivered state (i.e. with the tempered martensite structure) within the heat affected zones.

The problems related to welding of the high strength steel, aimed for manufacturing of welded structures operating in the prominent wear conditions, is considered in this paper. The paper presents an analysis of possibilities and prescribing the technology for welding the high strength steel HARDOX 450. The methodology for estimate the weldability of this steel was established in the

Surface hardness measurements of the steel revealed a poor effect from the carburization, the hardest surface was measured at 735 HV. This could be explained by a probable surface decarburization of the original Hardox 450, which was discovered by microstructure examinations and

ABSTRACTThe microstructure and microhardness distribution in the surface of low carbon Hardox 450 steel coated with alloyed powder wires of different chemical compositions are studied. It is shown that the microhardness of 68 mm thick surfaced layer exceeds that of base metal by more than two times. The increased mechanical properties of surfaced layer are caused by the submicro and
