Outokumpu has announced collaboration with Tubacex, a global stainless steel and high nickel alloys tubular solutions supplier. As part of the collaboration, Tubacex has used Outokumpu Therma 253 MA billets as the starting material for production of seamless tubes optimized for very high service temperatures.
Tubacex produces hot and cold finished tubes for applications in the chemical, petrochemical and power generation industries. Production of high temperature seamless tubes is very demanding and the new product development required extensive cooperation between Tubacex and Outokumpu technical teams.
Olle Källgren, Outokumpu Long Products said: “Our Therma 253 MA grade can give you a longer product lifecycle compared to other products like 309S/4833 and 310S/4845. MA grades have also significantly higher mechanical strength at high service temperatures. This means you can use thinner gauges, to increase efficiency and savings on material costs, or use the same thickness with higher loads to increase productivity.”
Outokumpu Therma 253 MA (1.4835/S30815) is a stainless steel product developed by Outokumpu providing excellent oxidation and creep resistance in cyclic conditions that is best employed in temperatures up to 1150°C. The grade is available in coil, sheet, plate, bar, wire rod, semi-finished long products and pipes.
