The Astro 900 Crusher Rod Electrode has been designed to provide porosity free welds on all weldable grades of carbon steel. The weld deposit is also smooth, uniform and will give excellent service life to new and worn parts.
Astro 900 Crusher Rod AC/DC Electrode is a versatile Electrode for Heavy Impact and Abrasion. Superior Alloy for both Impact and Abrasion Resistance. Astro 900 crusher is an electrode for heavy impact and abrasion on both carbon and manganese steels. It can be used AC or DC, and offers smooth arc, low spatter and high deposition.
The coating also imparts alloying ingredients to the weld deposit which enrich the weld. Deposition rates are considerably faster than conventional hardfacing electrodes.
Check cracks may appear when new weld cools, the cracks will not change wear resistance, but will aid in prevention of distortion. Two layers recommended.
Extremely Quick Deposition Rate
Unprecedented Impact Resistance
Designed Especially for Crusher Service
Excellent for Rolling Mill Guides, Rippers
Crushing Equipment etc.
Hardness on SAE 1020 steel: 59-62 R.C.
Deposits are non-machinable and cannot be heat treated
Both stringer and weave beads may be employed
Gyratory crusher parts
Conveyor bucket lips
Most parts subject to heavy impact
On carbon steels, build up to approximate desired shape with ASTRO 616-A.
On manganese steels, use ASTRO 902.
Apply ASTRO 900 to a maximum of 7mm or two weld layers.
NOTE: When welding manganese steels, do NOT overheat base metal (315C / 600F MAX)
