Lahore Casting pours 8 alloy families — Alloy Steel, SG Iron, Grey Cast Iron, Manganese Steel, High Chrome Iron, Stainless Steel, Carbon Steel, Mild Steel — by sand casting from 1 kg to 500 kg at Mominpura Road, Lahore, Pakistan. Every heat is checked on an OES spectrometer before it is poured, and a material test certificate is issued on request. Any of the 40 standard castings, or your own drawing, can be poured in any of them.
Steel with chromium, molybdenum or nickel added so it can be quenched and tempered to a strength plain carbon steel cannot reach. The choice when a part is loaded hard and must not fatigue.
Cast iron in which the graphite is formed into spheres rather than flakes, so it bends before it breaks. It has most of grey iron's castability with a large fraction of steel's toughness.
The oldest and most forgiving casting iron. Flake graphite makes it damp vibration, machine easily and fill thin sections - which is why machine bases and housings have been made from it for two centuries.
Austenitic steel with 12-14% manganese. It arrives soft and gets hard where it is hit: the surface work-hardens under impact while the core stays tough, so it wears in rather than out.
Iron carrying enough chromium to form hard chromium carbides right through the section. It is the most abrasion-resistant alloy on this list, and the most brittle - the two go together.
Chromium-nickel steel that carries its own oxide film, so it does not rust. CF8M is the cast equivalent of 316 - the same molybdenum that buys resistance to chlorides and acids.
Medium carbon steel, around 0.45-0.50% carbon. Strong enough to be heat treated, plain enough to stay affordable - the default when a part must be steel but does not need alloying.
Low carbon steel, around 0.20% carbon. It welds without preheat and machines cleanly, which matters more than strength on parts that are fabricated into an assembly.
