Cast Alloys & Technical Info
 
 
 

Cast Alloys

Our products are utilized in various high temperature applications. Typically the service temperature ranges between 400 to 1100 degrees centigrade. Our products are used as stressed components in many of these demanding environments.

We also cast some of our own alloys, these grades have been developed for some our of clients specifically suited to their service conditions. We can assist our clients at every step for the right alloy selection of their product to get optimum results.

We are also working on the development of Inter Metallic Alloys, soon to be introduced in the market.

High Alloy

    • The alloys we cast are various High Alloy Grades like HF, HK, HP, HU, HT, In519, 316L etc.

Low Alloy

    • Our typical low alloy grades are En18, En19, En24, .
    • Our Static Cast Work Rolls and Centrifugal Cast Work Roll Sleeves are used for hot rolling of various materials. The typical roll grades we cast are Adamite steel, High chrome steel etc.

Centrifugal Technology

Overview of the Centrifugal casting process

    • Centrifugal casting is the casting process specifically adapted to the production of
    • cylindrical parts.
    • Centrifugal casting pipes are made by pouring molten metal into a rotating mould. The metal is solidified in cylindrical shape with high centrifugal force.
    • The casting is usually a fine grain casting with a very fine-grained outer diameter, which is resistant to atmospheric corrosion, a typical situation with pipes. The inside diameter has more impurities and inclusions, which can be machined away.  
    • The process can also be adopted to produce various other products, using molds that can be permanent or expendable. The rotational speeds are lower than those used in centrifugal casting. This process is used for making wheels, nozzles, valve bodies etc. This process is known as Semi-Centrifugal Casting.
 

Benefits of the centrifugal casting process

    • Solidification happens at up to 120 times the gravitational acceleration, and consequently yields a highly compressed structure.
    • The process is gravity and pressure independent.
    • Mechanical properties substantially better as compared to static casting (can be compared with forged parts)
    • The Directional solidification of the casting, yielding a very uniform structure, free from inclusions and blow holes.
    • Not restricted to patterns (moulds, being permanent, mostly used from the extensive stock)
    • No restriction on tube thickness and weight (dependent on mould size).
    • No runners or risers are required for making of the product.
    • Practically any material can be cast ranging from low-alloy to iron-free
      materials, e.g. Cr-Ni-Mo.
    • Composite and Bimetallic castings can also be produced for e.g.: to make a hard outer and ductile inner layer.
    • The absence of anything preventing contraction during solidification results in castings with minimal residual stress.
