Characteristics of G18NiMoCr36

G18NiMoCr36 generally refers to a high alloy cast steel material. However, this is not a trade name or standard classification of a particular material. Therefore, it is not possible to provide information about its specific features or standards.
However, some properties for similar cast steel alloys in general may include:

  1. Chemical Composition : High alloy cast steels generally contain various proportions of carbon, nickel, chromium, molybdenum, manganese, and other alloyed elements. The ratios of these elements determine the mechanical and chemical properties of the material.
  2. Strength Properties : High alloy cast steels generally have high strength, hardness and wear resistance.
  3. Corrosion Resistance : The presence of alloying elements such as chromium makes high alloy cast steels resistant to corrosion.
  4. Machinability : High alloy cast steels may require special attention in casting and machining processes. They can be shaped by heat treatments and other processing methods.
  5. Applications : High alloy cast steels are generally used in the production of parts operating under heavy loads, they are especially preferred in industrial applications exposed to wear and high temperatures.

However, it is important to consult the material's specific standards or manufacturer's technical data sheets for more information on specific properties and applications for G18NiMoCr36. Specifications for this particular material may vary from product to product and manufacturer to manufacturer.
