T91 steel pipe is a steel alloy tube t91 51X3.5, T91 martensitic steel steel is the new American Ridge National Laboratory and the US as a tree Combustion Engineering Metallurgical Materials Laboratory developed in cooperation. It is based on reducing the carbon content of steel 121MoV strictly limit the content of sulfur, phosphorus, and add a small amount of vanadium, niobium alloying elements. According ASTM213 / A213M-85C, the chemical composition of T91 steel in Table 1. T91 steel and the corresponding number of German steel X10CrMoVNNb91, Japanese steel imports for HCM95 t91 alloy, France was TUZ10CDVNb0901. Table 1 T91 steel chemical composition% of our ten years of professional production of steel, the technical performance of steel, steel cash resources, the spot price of steel t91, the outside diameter of the steel pipe recently this product requirements. Pipe is an integral part of the major national construction steel, steel pipe widely in the chemical. Petroleum infrastructure, weather related products, petroleum power plant boiler Shanghai t91 alloy tubes, automotive parts applications, building support, marine pipeline. 20G steel, 15CrMoG steel, 12Cr1MovG 16Mo3 steel pipe steel P91, P22 steel, T91 steel, T22 steel, the wide range of applications Wb36 steel pipe is unprecedented, all to be hundred percent quality steel to ensure quality requirements for the use of location t91 Seamless | Katherine source of steel (certified) | Wanzhou t91 provided by source Pipe Co., Ltd.
