64 HRC in a Single Layer for Extreme Abrasion

OK Selectrode 84.84 has been developed with unique alloying generating an equally unique microstructure rich in carbides. This system assumes a high packing density leaving virtually no matrix unsheltered. Dilution of carbide in base metal is minimum as expected from the super convex bead shape. This. results in full hardness attainment in one layer itself and uniform hardness throughout the bead. ALLOY BASEFe, Si, C, Cr, Ti, V

SPECIAL FEATURES

• Full and uniform hardness in one layer only Distribution of light micro carbides for resistance to abrasion by fine particles

APPLICATIONS

Side ribs of oil drill bit and tri-cone rock roller bit. New line concrete mixer paddles, dredger bucket tooth area. Other typical applications include hammers, scrapers, knives, shovel bucket and shovel teeth. PROPERTIESHardness : 62-64.5 HRC WELDING PROCEDURE
Use stringer beads. Weaving, if really unavoidable, should be as less as possible If carpet coverage is required the overlap between successive beads should be minimum Do not peen the bead while hot The hardness is not affected by cooling rate, however, for best results employ normal air cooling

CURRENT RANGE : (AC 70, DC+/-)

Low Heat Build-up on Manganese Steel

This is a low heat input electrode suitable for surfacing, building up and joining of austenitic manganese steels of plain & alloy types. The austenitic deposit is more resistant to cracking, deformation and heat embrittlement. The deposit is tough to witbstand metal to metal impact. It resists wear under rolling abrasion at high contact pressures. ALLOY BASEFe, C, Mn, Ni SPECIAL FEATURES

• Graphite free coating avoids carbon pick-up
• Deposit gives high strength, combined with excellent resistance against impact
• Smooth are, fine ripples and a fluid but controlled slag, which is easily detachable

APPLICATIONS

Manganese steel shovel bucket teeth & lips, pulverizing hammers, beaters, grinding ring & rollers, gyratory crusher mantle and liners, cone and ring, jaw crusher plates etc. PROPERTIESHardness : As deposited : 22-24 HRC Work hardened : 42-45 HRC

WELDING PROCEDURE

• 14% Mn steel should never be preheated for welding
• Welding should be done in stringer beads directing the towards the weld pool
• Heat input to the base metal should be kept minimum, if required skip welding/back step welding can be adopted
• The weld bead must be peened with ball pen hammer immediately after welding
• Quenching has no adverse effect on welding and should be adopted whenever possible after slag removal and peening. If possible the Mn steel job can be submerged in water during welding

Sugar Mill Roller Dry and Wet Arcing

OK 84.76C is a basic coated high efficiency high chromium carbide type electrode for roughening the wet mill rollers used in the sugarcane crushing. It provides an electric arc of spray type, depositing weld metal in the form of fi ne globules in the grooves of the mill roll thus increasing its gripping and dragging power. Enormous rollers are used in the sugarcane crushing process, which are subjected to excessive wear during the season. These rollers have to be continuously roughened, even when the crushing is in full swing. These are smothered in crushed, sludgy cane and the surface is wet. OK 84.76C accommodate these conditions and deposit a dispersion of small, hard and wearresistant globules that fastens to the sidewalls of the ridges of the roller. It can be observed that the roughness created on the surface of the mill roll increases its productivity considerably, permitting better utilization of the grounded material, which in turn increases the quantity of the sugarcane to be processed.

SPECIAL FEATURES

• Spray type arc for better distribution of the globules
• Good bonding with the rollers, even in wet condition

HARDNESS : 57 – 64 HRCWELDING PROCEDURE

• Hold the electrode at right angles to the fl ans of the profile
• Use "cold welding" technique; avoid excessive heat in the weld area
• Use DC positive, for better results

DEPOSITION DATADeposition rate : 2.2 kg / hrDeposition Effi ciency : 69%Metal Recovery : 205% WELDING CURRENT : DC +/- , AC 70

Ductile Crack-Free Deposit for Mn Steel Build-upHigh efficiency electrode with special coating, to resist massive impact by mineral or metal along with moderate to good resistance to mineral abrasion. Despite the common tendency of cracking in manganese steel, this high purity bead remains ductile and crackfree even after die penetration tests. The alloy also shows reluctance to necking in tensile specimen. In abrasion area also it is superior to all the above except high-density pre-formed carbides. ALLOY BASEFe, Mn, Ni SPECIAL FEATURES

• Ripple free deposit
• Auto slag detachment, free from slag inclusion
• Low heat input even at high current capacity

APPLICATIONSCrushers, earthmoving equipment, hammers, shovel track pads, wear plates, building up manganese steel components, buffering before carbide hardfacing deposit. PROPERTIESHardness : As deposited : 22-23 HRC Work hardened : 42-44 HRC

Ultimate Resistance to any Type of Wear

Terroweld EWR deposits a low dilution, high abrasion resistant alloy that is stainless and does not tarnish even in presence of aggressive chemicals. The deposit is ripple-free and uniform. The electrode performs well even in out-of-position surfacing. Oxidation resistance of the deposit is maintained upto a temperature of 11 aaoc. Hardness retention at high temperature is also remarkable.
