A 30 MW captive power plant using waste gases and coal-fired burners ensures consistent and quality power supply, as well as cost competitiveness.
Stainless Steel
Stainless steel is steel containing 10.5% or more of chromium. which imparts it with corrosion resistant properties,by the formation of an impervious layer of chromium oxide on the surface.
Stainless Steel finds many applications,which include:
- Construction industry
- Boiler industry
- Pumps and Shaft applications
- Flanges
- Surgical applications
- Cutlery
- Weaving and Knitting Wires
- High Temperature Corrosion Resistance Chemical and Petrochemical industries
- Springs etc.
