Our Castings- The Scope

Having dealt with customized castings since last two decades, we have gained expertize with various grades of castings. We have all sorts of required facilities for manufacturing Carbon Steel, Manganese Steel, Stainless Steel, Alloy Steel, High Chrom Iron, Special Ni Hard & Ductile Iron. The choice for grades of castings depends on the application of the castings. For your reference we have described the purposes/applications of various grade to enable you to choose appropriate for your applications and for easy reference.


Range of Products

Carbon Steel

Carbon steel is an alloy consisting of iron and carbon. Several other elements are allowed in carbon steel, with low maximum percentages. These elements are manganese, with a 1.65% maximum, silicon, with a 0.60% maximum, and copper, with a 0.60% maximum. Other elements may be present in quantities too small to affect its properties.


Grades of Carbon

There are four types of carbon steel based on the amount of carbon present in the alloy. Lower carbon steels are softer and more easily formed, and steels with a higher carbon content are harder and stronger, but less ductile, and they become more difficult to machine and weld. Below are the properties of the grades of carbon steel

  • Low Carbon Steel – Composition of 0.05%-0.25% carbon and up to 0.4% manganese. Also known as mild steel, it is a low-cost material that is easy to shape. While not as hard as higher-carbon steels, carburizing can increase its surface hardness.
  • Medium Carbon Steel – Composition of 0.29%-0.54% carbon, with 0.60%-1.65% manganese. Medium carbon steel is ductile and strong, with long-wearing properties.
  • High Carbon Steel – Composition of 0.55%-0.95% carbon, with 0.30%-0.90% manganese. It is very strong and holds shape memory well, making it ideal for springs and wire.
  • Very High Carbon Steel - Composition of 0.96%-2.1% carbon. Its high carbon content makes it an extremely strong material. Due to its brittleness, this grade requires special handling.

Manganese Steel

Manganese steel has been used in the mining industry, cement mixers, rock crushers, railway switches and crossings, crawler treads for tractors and other high impact and abrasive environments. It is also used in high impact environments like inside a shot peening machine.

Many of Manganese Steel uses are often limited by its difficulty in machining; sometimes described as having almost zero machinability. The metal cannot be softened by annealing and hardens rapidly under cutting and grinding tools, usually requiring special tooling to machine. The material can be drilled with extreme difficulty using diamond or carbide.

Stainless Steel

Stainless steels are notable for their corrosion resistance, which increases with increasing chromium content. Additions of molybdenum increase corrosion resistance in reducing acids and against pitting attack in chloride solutions. Thus, there are numerous grades of stainless steel with varying chromium and molybdenum contents to suit the environment the alloy must endure. Stainless steel's resistance to corrosion and staining, low maintenance, and familiar lustre make it an ideal material for many applications where both the strength of steel and corrosion resistance are required.

Stainless steels are rolled into sheets, plates, bars, wire, and tubing to be used in: cookware, cutlery, surgical instruments, major appliances; construction material in large buildings, such as the Chrysler Building; industrial equipment (for example, in paper mills, chemical plants, water treatment); and storage tanks and tankers for chemicals and food products (for example, chemical tankers and road tankers). Stainless steel's corrosion resistance, the ease with which it can be steam cleaned and sterilized, and no need for other surface coatings has also influenced its use in commercial kitchens and food processing plants.

Alloy Steel

Alloying elements are added to achieve certain properties in the material. As a guideline, alloying elements are added in lower percentages (less than 5%) to increase strength or hardenability, or in larger percentages (over 5%) to achieve special properties, such as corrosion resistance or extreme temperature stability. The following is a range of improved properties in alloy steels (as compared to carbon steels): strength, hardness, toughness, wear resistance, corrosion resistance, hardenability, and hot hardness. To achieve some of these improved properties the metal may require heat treating.


Common Application:

Some of these find uses in exotic and highly-demanding applications, such as in the turbine blades of jet engines, in spacecraft, and in nuclear reactors. Because of the ferromagnetic properties of iron, some steel alloys find important applications where their responses to magnetism are very important, including in electric motors and in transformers.

Ductile Iron

The common defining characteristic of Ductile Iron of materials is the shape of the graphite. In ductile irons, graphite is in the form of nodules rather than flakes as in grey iron. Nodule formation is achieved by adding nodulizing elements, most commonly magnesium (magnesium boils at 1100 °C and iron melts at 1500 °C) .


Common Application:

Much of the production of ductile iron is in the form of ductile iron pipe, automotive components, where strength must surpass that of aluminum, other major industrial applications include off-highway diesel trucks, Class 8 trucks, agricultural tractors, and oil well pumps.
