T11 Tube Material is a low alloy ferritic stainless steel. There are carbon， silicon， manganese， nickel， phosphorus， chromium， sulfur and molybdenum in the content. The 0.5% carbon and 1% chromium bring the T11 Tube Material the good strength and corrosion resistance properties.
ASTM A213 T11 Tube is a boiler class stainless steel tube that is made from different material grades. The tubes are used in heat exchangers， super heaters and in boilers. The qualities of the pipes make them available for the high temperature services.
TONG CHUANG Group is a manufacturer and supplier of these pipes in larger quantities. The ASME SA213 T11 Seamless Tube consists of carbon， manganese， phosphorous， sulfur， silicon， nickel， chromium and molybdenum. The composition provides the material with high tensile strength， high yield strength and high Brinell numbers.
