LOW CARBON STEEL GRANAL ADVANTAGE COST
• Performance over 20% against high carbon shots
• Less wear of machinery and equipment due to the greater absorption of energy in the impacts in the pieces
• Particles free of defects generated by thermal treatment, fractures or micro cracks
IMPROVING THE ENVIRONMENT
• Powder reduction
• Bainitic microstructure guarantees that they will not break during its useful life
GENERAL APPEARANCE
The shape of the low carbon steel shot is similar to spherical. The minimal presence of elongated, deformed particles with pores, slag or dirt is possible.
This does not affect the performance of the shot, it can be confirmed by measuring its performance on the machine.
HARDNESS
The bainitic microstructure guarantees a high degree of hardness. 90% of the particles are between 40 – 50 Rockwell C.
The low carbon in balance with the manganese guarantees a long useful life of the particles, thus improving the cleanliness of the pieces, since with mechanical work they increase their hardness.
The energy of the shot blasting is absorbed mainly by the parts, thus reducing the wear of the machine.
CARBON GRANULATION, HIGH PERFORMANCE
The use of the low carbon steel shot has scope for machines that have turbines of 2500 to 3000 RPM and speeds of 80 M / S.
For new equipment that uses 3600 RPM turbines and speeds of 110 M / S, these are requirements to increase productivity.
