Steel shots and steel grits are used in both static & site blasting equipment, materials and abrasives used for surface preparation can be hazardous if used carelessly. Many natural regulations exits for those materials and abrasive that are considered to be hazardous during or after use (waste management), such as free silica or carcinogenic or toxic substances.
Steel Grits is fabricated by crushing hardened shot, screening the resulting media and tempering it to a desired hardness. It is used in conting and rust removal where speed of cleaning is serious & rough finish is acceptable. Steel grit’s superior hardness and precise microstructure provides maximum durability and impact energy transfer. Highly demanding, aggressive applications are ideal for steel grit.
Steel abrasives are particles of steel with high carbon content that are utilized as abrasive and peening media. Steel abrasives are available in two types based on their shape; shots and grits. Steel shots are spherical grains of molten steel produced through a granulation (atomization) process in requisite sizes or hardness. The steel abrasives market is expected to grow at a good rate in the coming years. Rapid industrialization and expansion of automotive production are the key trends stoking market growth. To decrease environmental issues, leading manufacturers in the automobile sector are manufacturing low-weight products, which emit low carbon dioxide, which are economical and yet provide superior performance.
The Indian Steel Abrasives industry is catered to by a few large players and numerous smaller players that specialise in select products where imports from China cater to the lower end of the market. Due to the soft market conditions in many advanced economies, India is becoming a focus market for major global players resulting in intense competition.
Few Indian major players are as under:
· 3M India Ltd.
· Grindwell Norton Ltd.
· Hi-Tech Recycling (India) Pvt. Ltd.
· Orient Steel & Inds. Ltd.
· Rotocast Industries Ltd.
· Silcal Metallurgic Ltd.
· Vinayak Steels Ltd.
