T91 alloy tube is like a tree Ridge National Laboratory of the United States and the American Combustion Engineering Metallurgical Materials Laboratory cooperation in the development of the new martensitic steel. It is based on reducing the carbon content of the steel 9Cr1MoV, strictly limited sulfur, phosphorus content t91 pipe, adding a small amount of vanadium, niobium alloying elements. No. K90901 T91 T91 alloy tube alloy tube T91 alloy tube specifications: 8-1240 × 1-200mm T91 alloy tube Overview: T91 alloy tubes are boilers, heat exchangers heating and ferritic alloy steel seamless and Olympic (ASTM A213 / A213M-07a) uses: for low and medium pressure boiler (working pressure is generally not more than 5.88Mpa, operating temperature of the heating surface tubes at 450 ℃ or less); for high-pressure boilers (above 9.8Mpa working pressure in general, where the sale t91 The operating temperature of heating surface tubes between 450 ℃ ~ 650 ℃), the economizer, superheater, reheater, petrochemical industrial pipe. T91 alloy tube heat: T91 final heat treatment for normalizing + tempering, normalizing temperature of 1040 ℃, holding time of less than 10 min, the tempering temperature is 730 ~ 780 ℃ t91 steel 51X3.5, many holding time for 1h, after the final heat treatment is tempered martensite steel Katherine source is in production, processing, storage and sales of integrated enterprise, annual sales of seamless pipe products factory and agency distribution: Cheng Gang, Xining , Baotou, Tianjin Steel, Steel and other major steel seamless spot quality, alloy pipe, large diameter thick-walled seamless pipe, galvanized pipe, stainless steel and other steel products; Material: 20 #, 35 #, 45 #, 16Mn, 27SiMn, 40Cr, 35CrMo, 12Cr1MoV, 15CrMoG, 42CrMo, 30CrMo, 38CrMoAl, 25CrMnMo, P110, P91, N80 and other performance standards for: precision light pipe (GB3639-2008), structural pipe (GB8162- 2008), fluid pipe (GB8163-2008), low-pressure boiler pipe (GB3087-2008), high-pressure boiler pipe (GB5310-2 t91 steel pipe 51X3.5_ Jiamusi t91_ Katherine source provided by Liaocheng Katherine source Pipe Co., Ltd. .
