PZPS successfully produced a trial batch of cold-rolled strip from heat-resistant nickel-chromium alloy KhN53BMTYU

At Petersburg Plant of Precision Alloys an experimental batch of cold-rolled strip from a high-quality heat-resistant nickel-chromium alloy alloyed with iron, molybdenum, and niobium was successfully produced. This was the first experience of producing KhN53BMTYU by classical metallurgical technologies rather than powder metallurgy. In mechanical properties the alloy is similar to the well-known foreign material NN 718.

Chemical composition and alloy properties

Nickel-chromium alloys are produced from pure charge materials by vacuum remelting. Thanks to alloying with chromium, iron, molybdenum, and niobium the materials are ideal for use in extreme conditions, in particular for high-temperature service.

Special alloy properties:

• Corrosion resistance: they have elevated resistance to various aggressive environments, including atmosphere, seawater, acids, alkalis, and chlorides. This allows use of materials where other metals fail or lose their properties.
• Durability: they belong to high-strength alloys and have excellent fatigue strength under prolonged service in high-temperature environments. This makes nickel-chromium alloys ideal for parts operating in extreme conditions.
• Heat resistance: the alloys retain high strength and stability of physical and mechanical properties at temperatures up to 1000°C. Thanks to this they have become indispensable materials for aerospace, aviation, energy, and oil-refining industries.
• Oxidation resistance and thermal stability: they have high resistance to oxidation and oxidizing corrosion at high temperatures without forming an oxide layer, making them suitable for environments with active oxygen.

Applications

Heat-resistant nickel-chromium materials are well suited to severe operating conditions. They are widely used in industries that require high resistance to elevated temperatures, aggressive environments, and other extreme conditions, for example when creating gas turbine engines and chemical equipment.

Producing heat-resistant nickel-chromium alloys opens new prospects for modern technological industry and underscores the plant’s position as a leader in innovation and development.
