Steel is a very important material for the blades of steam and gas turbine units. These steels require high technology, high strength and high durability to work reliably under extreme conditions. The following are the different types of steel used in steam and gas turbine units.
1. High temperature steel: This steel is suitable for blades under high temperature conditions and can usually withstand temperatures of up to 650 ° C. This steel is required to have good corrosion resistance, oxidation resistance and high strength.
2. Stainless steel: This steel has very good corrosion and wear resistance. Because of their good corrosion resistance and high temperature properties, they are well suited as blade materials for steam and gas turbine units.
3. High alloy steel: This steel is a material with extremely high strength and high durability. They are commonly used on blades under high temperature and pressure conditions, and can be resistant to corrosion and fatigue.
4. Cast steel: This steel is very suitable for large turbine sets. The casting method can produce large blades and can adapt to various design shapes.

BLADE STEELS FOR STEAM AND GAS TURBINES are high performance materials that are essential for the reliable and efficient operation of these machines. There are several grades of blade steels that are commonly used in steam and gas turbines, each with their own unique advantages and properties.
One of the most common blade steels is 9Cr-1Mo-V, which has excellent high temperature strength and resistance to corrosion and fatigue. This steel is often used in the manufacture of steam turbine blades, where it is able to withstand the high temperatures and pressures of the steam environment.
Another popular blade steel is 17-4PH, which is a precipitation hardening stainless steel that combines high strength and toughness with good corrosion resistance. This steel is often used in gas turbine blades, where it is able to withstand the high speeds and temperatures of the combustion process.
Other blade steels that are commonly used in steam and gas turbines include 12Cr, 18Cr, and 22Cr, each with their own unique properties and advantages.
