The upside of having an in-house melting shop is the ability to smelt grades that are popular and also exotic. Our metallurgy experts treat steelmaking as an art and this finesse results in excellent microstructure with the least variation in parameters, batch to batch.
The Austenitic steel grade range displays high toughness and performs well in elevated temperatures too. Our Duplex steel has high chromium and low nickel concentration and leads to good resistance to stress corrosion.
Our Martensitic grades are magnetic but has great hardening properties and withstands duress with ease.
The corrosion resistance of austenitic stainless steel is due to its high concentration of chromium (16-26%), nickel (35%), and copper (up to 45%). It is heat resistant and the most preferred type of steel.
It makes up the majority of steel production. Austenitic stainless steel is often used in household appliances and has applications in the industrial, architectural and medical sectors.

A combination of both austenitic and ferritic steel, duplex steel has characteristics of both.
Thus, it is both heat and corrosion-resistant. Duplex steel is perfect for construction and the oil and gas industry.
Comprising high chromium content (up to 27%) and low carbon content (>0.20%), ferritic stainless steel is highly resistant to corrosion.
Because of its low thermal expansion coefficient, it is used in high-temperature applications. Being a good heat conductor ferritic stainless steel is also used in furnaces. The name “ferritic” refers to its composition - ferritic steel contains ferrite, an iron compound which makes this steel magnetic.
Martensitic stainless steel contains chromium but higher carbon (1%) and little to no nickel. It may contain molybdenum.
Martensitic stainless steel can be hardened because of the presence of carbon. It is also resistant to corrosion but a little brittle. The carbon content in this steel determines the usage - 0.4% carbon for engineering applications and above 0.4% for medical tools, blades and bike parts.

Apart from chromium (17%) and nickel (4%), the addition of elements like aluminium and titanium to precipitation-hardening steel (PH steel) can increase its strength.
The presence of these elements causes dislocations in the lattice structure of the steel, causing hardening. PH steel has uses in the construction, aerospace and chemical industries.
