Corrosion of compressor blades can occur due to moisture containing salts and acids collecting on the blading. To prevent the corrosion, GE has deve loped patented aluminum slurry coatings for
Usually 12% Cr stainless steel is used for the blades, but for long blades where stresses is higher, and for first-stage blades where scaling easily occurs, 17-4PH is used. Compared to 12% Cr stainless steel, 17-4PH steel has better corrosion resistance against elements, such as H2S in geothermal steam, better resistance against stress Modular Steam Condenser Replacements Using Modular Steam Condenser Replacements Using Corrosion Resistant High Performance Stainless Steel Tubing John M. Burns, P.E. Burns Engineering Services, Inc. John Tsou, P.E. Consultant Abstract Condenser performance and reliability have a significant impact on the electric generation of Protecting Your Steam Turbine from Corrosion Power Oct 11, 2017 · Most difficulties with these salts occur in the LP turbine. The entering steam still has a reasonable amount of superheat, but as the steam reaches the last few rows of turbine blades
existing steam turbine generator blades can be made to increase turbine efficiency. Finally, the overall sustainability of steam turbine generators is discussed and the impact that the design of the blades has on the sustainability of these generators is presented. stainless steel type AISI commonly used Steel of Turbine blade B50A947 A4 - Tool & Die SteelsSteel of Turbine blade B50A947 A4 Quick Details By 50 t, 3 LF electric arc furnace smelting furnace t electrode, electroslag remelting, insulation, annealing, 800 650 * 4 mill production process leaves Phi 180 steel refining, casting (%:0 06 ~ 0 15C, 0 25 ~ 0 80M 11 25 ~ 13 n, 00C R, M o = 0 30, 60N Steels of Blade for Steam Turbine - Special SteelSteels of Blade for Steam Turbine Products List This page has 3 qualified content. 1Cr11Ni2W2MoV We are mainly engaged in the special steel, stainless steel, tool steel, alloy steel, high temperature alloys, heat-resistant steel rod, plate /sheet, strip/coil, steel wire,tube/pipe, forgings and finished machining,etc. services.

Steels of blade for steam turbine. The main products are Steel for Turbine Blade products,widely used in aviation,aerospace,machinery,automobile,petroleum,chemical,and mould industries and got the high praise from the general customers. The Hardness and Microstructure of The Modified 13Cr Keyword-Steam turbine blade, Martensitic stainless steel, Carbide I. INTRODUCTION Martensitic stainless steels were commonly used for manufacturing component due to their high mechanical properties and moderate corrosion resistance, operating at Water droplet erosion of stainless steel steam turbine bladesAug 16, 2017 · Stainless steel ex-service steam turbine blades were examined in this study. These blades were provided by ALSTOM-Power, Switzerland to identify the WDE mechanisms on different sections of the blades. The service environment of these blades were considered harsh.
