Tubes for Recuperator Applications
Sandvik Asia Pvt Ltd offers productivity boosting Tubes for Recuperator Applications. Sandvik has two grade solutions – Sandvik 253 MA™ and Sandvik 4C54 – for overcoming the challenges faced by recuperator tubes when used at high temperature and severe corrosion conditions. Sandvik 253 MA™ is austenitic chromium-nickel steel alloyed with nitrogen and rare earth metals. Due to its high creep strength, very good resistance to isothermal particularly cyclic oxidation and combustion gases, good structural stability at high temperatures is ideal for use in metal industries such as iron and steel production, DRI, copper smelters, glass and petrochemical industry. The grade is also used in various industry segments because of its characteristics of handling temperatures up to 1150°C and good weldability. While Sandvik 4C54 is ferritic, heat resistant, stainless chromium steel, characterised by extremely good resistance to reducing sulphurous gases very good resistance to oxidation in air, good resistance to oil-ash corrosion, molten copper, lead and tin. This grade is extensively used in the steel, metallurgical, glass, chemical industry and as thermocouple protection tubes.
