| BRAND | PRODUCT DESCRIPTION | WELD METAL PROPERTIES (AS WELDED) | APPLICATIONS | |
|---|---|---|---|---|
| MAILHARD - RI | A rutile type electrode giving a machinable deposit of hardness 250BHN approximately | Hardness on 3 layers 250 BHN (approx.) | Ideal for rail crossing gear,shafts,hammers,axles etc., | |
| MAILHARD - RII | A rutile type electrode giving a deposit of hardness 350 BHN approximately and has good resistance to impact.It has good resistance to sliding and friction. | Hardness on 3 layers 350 BHN (approx.) | Typical applications include drive sprock - ets,wheels, shafts,pullies,axles, rail crossings,etc | |
| MAILHARD - RIII | A rutile type electrode giving a non machinable deposit of hardness 600 BHN approximately.An initial buffer layer of Mailex -18/8/6SS is recommended while using on austenitic manganese steels. | Hardness on 3 layers 600BHN(approx) | Ideal for hardfacing applications on canes and bamboo cutting knives,shear blades,crusher hammers, sprockets etc., | |
| MAILHARD- BIIILH | A heavy coated,basic type hydrogen controlled iron powder electrode with a smooth arc,medium penetration and least spatter.Gives a hard and non-machinable deposit which can withstand very high abrasion and impact and can only be ground. | As Welded Hardness on 3 layers 550 BHN(approx.) | Applications includes bamboo,chipper knives sprockets conveyor buckets crusher jaws cane cutting knives,oil expeller worms etc. | |
| MAILHARD- BV | A medium heavy coated basic type electrode with a smooth arc and least spatter and works easily even at low currents.Gives an air hardening alloyed cast iron deposit which is extremly hard and resists very high abrasion and moderate impact.Ideal for hardfacing application requiring resistance to scratching or mild grinding abrasions. | Hardness on 3 layers 600 BHN(approx.) | Applications includes cement die rings,oil expeller worms, concrete mixer blades screw conveyors, muller tyres bucket lips etc., | |
| MAILMANGAN- 12 | A heavy coated,basic type electrode with mild steel core wire giving a deposit of 12%Mn. Gives a smooth arc,least spatter and also gives a weld deposit of hardness 200BHN in as welded condition which work hardens to over 500BHN under impact. | Hardness - 200 BHN (approx.) increases to 500BHN under impact in service. | Typical application includes rock crushers,steel rails, cement grinding rings,ball mills, manganeese steel parts of earth moving equipments, surfacing of hammers,dredger bucket teeth etc., | |
| MAILMANGAN- 14/4 | A heavy coated,low hydrogen type austentic manganeese steel electrode depositing 14% Mn and 4%Ni.The deposit is of workhardening type.Hardness increases from 200BHN in as welded condition to 500BHN under impact.For hard facing applications on mildsteel and low alloy steel buffer a layer of Mailex 18/8/6SS is recommended. | Hardness on 3 layers 200BHN (approx.) increses to 500BHN under impact in service | Ideal for managanese steel rails, cement grinding rings, rock crusher jaws, crusher mantles, hammers, muller tyres etc.. |
