REVIEW OF THE WEAR AND GALLING

HardnessIn general,resistance to wear is increased by increasing hardness,provided other factors remain constant.There is some question,however,whether the controlling hardness is the bulk hardness or simply surface hardness.It has been stated that to increase wear resistance,hardness should be increased by alloying or heat treatment.Practical Data for Metallurgists - TimkenSteelJan 26,2017 aisi 1144 hardness problem#0183;Si 5 .15/.35,P 5 .035 max (SAE J1268),S 5 .040 max,Ni 5 .25 max,Cr 5 .20 max,Mo 5 .06 max These standard grades can have modifications in chemistry when ageed upon by user and supplier.Return to Table of ContentsPoor adhesion of Electroless Nickel Plating onto steelSo we sent one part to be checked for surface hardness,namely Vickers micro hardness,and the lab reported a hardness of 219.9 HVN -- that translates to Rockwell B hardness of 94.8 average of 10 measurements.The material spec for the 1010 Alloy states that the raw material received by our client has an average Rockwell Hardness of 48.2
