Lnc Grades - Brass Low Nitrogen Sand, Rcs 70-80%, Nitrogen <0.02% | Smooth Ejection, Thermal Shock Resistant, High Tensile Strength

We are an acclaimed name engaged in manufacturing and supplying a superior range of LNC Grades in Mumbai, Maharashtra, India. This Grade is suitable for Alloy Steel Castings, such as Tooth Points, Anchors, Valve Bodies. The sand has low nitrogen content and gives good surface finish. The sand exhibits slow rate of gas evolution.

Advantages:
This Grade of sand has been developed by us for steel foundries which was 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.
We can give 80% to 90% of RCS in 3 sieves distribution for better Surface finish and improved collapsibility.
