SAITRON HF 600 WH
Description:
SAITRON HF 600 WH is a basic coated low heat input “Anti-Wear” Mn-Cr-Ni-Mo alloyed work-hardening type hardfacing electrode. Excellent choice for surfacing and building-up worn out parts of mining equipments, earthmoving equipments, railway point and crossing and components made of manganese. Also used for joining on manganese casting to mild steel and other carbon steels. Weld deposit structure is austenitic, which is tough and easily work-hardened under impact condition, ultimately increasing the abrasion resistance.
 
Applications:
Used for surfacing in Cement plants, Mining equipments, Earthmoving equipments, etc. It is highly suitable for welding 13% Mn steel, rail point and crossing, rollers, mill hammers, Shovel, Dredge buckets, heavy crushing equipments like jaw crusher, Gyratory crusher cones, Swing hammers, Excavator teeth, crusher mantles and shredder hammers, hard surfacing of hot shear, rings in rotary furnace, forging moulds, hot forging dies etc. Used for overlaying, cushioning and building up of low, medium carbon, low alloy and Hadfield steels. Deposits are extremely tough and resist deformation under repeated impact loads.
 
Note on Usage:
Before welding remove oil and grease. Clean weld area by gouging or grinding to remove cracks or worn fatigued surface of components. Use electrode on AC/DC+ at the lowest amps. Maintain short arc and chip slag between passes. Electrode can be weaved 1.5 to 2 times its diameter. Peen deposits while hot. Preheat is usually not necessary unless very heavy sections are involved. No preheat should be used on manganese steel. Do not allow manganese steel interpass temperature above 2500 C.
