Product Profile of LNC Grades/Import Substitute Grade Resin Coated Sand
Shree Satya Pvt. Ltd. Supplies LNC Grades/Import Substitute Grade Resin Coated Sand. Shree Satya Pvt. Ltd. Manufactures various grades of Resin Coated Sands. LNC Grades/Import Substitute Grade Resin Coated Sand is used for Steel Casting/ Alloy Cast Iron/ S.G. Iron. This Grade is suitable for Alloy Steel Castings, such as Tooth Points, Anchors, and Valve Bodies. The sand has low nitrogen content and gives good surface finish. The sand exhibits slow rate of gas evolution.
Advantages of LNC Grades/Import Substitute Grade Resin Coated Sand are:
- This Grade of sand has been developed by us for steel foundries which were previously imported from Hepworth England & Bakelite Hylam Spain.
- The ejection of the moulds is smooth & there are no sub-surface cracks in the moulds.
- Surface finish of the moulds and the castings is good.
- Flowability of the sand is excellent, with good compactness, good build up and no peel back
.
- During pouring it will withstand thermal shock and the moulds will not crack during pouring.
- Very low Nitrogen content N2<0.02%
- Cold Tensile Strength is 40% to 50% higher than Hot Tensile Strength.
- Special RCS with C.T.S. 70% to 80% higher than H.T.S.
