450 is designed for metal to metal abrasion involving impact such as rolling or sliding parts in earth moving equipment where lubrication is not possible.
The weld deposits of 450 are martensitic in structure. Very good impact resistance; good abrasion resistance. Mine car wheels, brake drums, tractor rollers, undercarriage parts, shovel idlers, rollers, and hook rolls. Use DC Reverse Polarity (electrode positive).
The shielding gas should be 100% CO2 welding grade, however a 75% Argon + 25% CO2 mixture will increase the hardness slightly. Superior properties are achieved if an inter pass temperature of 300° ~ 480°F is maintained.
