Product Description
Since LSI’s first successful supplying of such great material for China Steel Corporation, LSI has completed more than 500 Kilometers S30815 (Alloy 253MA,EN1.4825) tubes and pipes for domestic and overseas customers and got 100% satisfaction with 0 complaints from customers and end users till today. UNS S30815, equal to Alloy 253MA and EN 1.4835 , include rare earth metals (REM) and suitable for very high temperature applications (700-1100℃),particularly for conditions involving erosion-corrosion in oxidizing and neutral environments, as well as sulfur attack. The excellent mechanical strength at high temperatures allows higher loads or thinner wall thickness than common high-temperature steels e.g. 309S (EN 1.4833) and 310S (EN 1.4845).
