What is NU•SOFT Steel Shot?
NU•SOFT Steel Shot is a metallurgically enhanced cast steel shot that was developed for cleaning soft, delicate metal parts in standard centrifugal wheel-type blast machines or in pressure-type air cabinets. NU•SOFT Steel Shot is round in shape with a hardness of between 12 and 15 Rockwell C (less than 200HV). Ultra-low in carbon, it has a density of slightly greater than 7g/cc. NU•SOFT Steel Shot is very durable with more than twice the life of standard SAE grades of cast steel shot and almost one thousand times the life of some competing abrasive media.

How is NU•SOFT Steel Shot made?
NU•SOFT Steel Shot is made from virgin, premium-grade cast steel shot—no other materials are added during the manufacturing process. Only fully round shot particles are shipped to you. Once in the furnace, the chemistry of the shot is carefully modified for optimum performance. GMA’s manufacturing facility is fully ISO compliant and has gained QS-9000 Certification.

What can NU•SOFT Steel Shot do?
NU•SOFT Steel Shot can:
• Remove heat treat scale from sintered powder metal parts
• De-flash aluminum die castings
• De-burr delicate stampings and fabrications
• Remove corrosion from machined surfaces
• Remove ash residue from caustic bath solutions
• Clean ceramic from intricate investment castings
• Eliminate build-up of release agents from molds

What won’t NU•SOFT Steel Shot do?
NU•SOFT Steel Shot won’t damage intricate detail work, “texturize” polished or machined surfaces or degrade threads of tapped holes. Because of its unique chemistry, NU•SOFT Steel Shot won’t work harden or distort the work piece, and it resists breaking down too rapidly into dust or fines. It won’t remove metal from part surfaces or damage blast machine wear parts.

How does NU•SOFT Steel Shot compare with other abrasives?

Just clean the inside of the blast machine and remove all traces of standard steel shot. Be sure to vacuum shot from around the screw auger at the bottom of the cabinet and from the boot of the elevator as well as from wear plates, reinforcing gussets, etc. (Remember: Any standard shot that is left to circulate will leave its mark.)

Check for proper adjustment of the air-wash separator, repair any leaks in the cabinet and replace worn wheel components.

NU•SOFT Steel Shot is equal in density to standard steel shot, so it will flow easily through your blast machine with no drop in amps to the wheel. If your blast machine utilizes a magnetic separator, it also will work fine with NU•SOFT Steel Shot.

Is NU•SOFT Steel Shot environmentally friendly?
NU•SOFT Steel Shot is a non-hazardous material and will not, in and of itself, generate a hazardous waste. The dust in the dust collector can be disposed of as with any standard shot blast waste. Be sure to keep the dust collector free of build-up by cleaning it regularly.

What sizes of NU•SOFT Steel Shot are available?
NU•SOFT Steel Shot is available in five (5) sizes ranging from NS-70 through NS-230, and each size has its unique applications.
