Hastelloy gate valve

Hastelloy gate valve

Characteristic  of Hastelloy gate valve

Hastelloy is a nickel-based alloys, the key is divided into B, C, G three series, it is mainly used in iron-based Cr-Ni or Cr-Ni-Mo stainless steel, non-metallic materials can not be used, such as the strong corrosion medium occasions in foreign countries has been widely used in petroleum, chemical industry, environmental protection and many other fields.

Mechanical Properties of  Hastelloy gate valve

Mechanical Properties of Hastelloy very prominent, it has high strength, high toughness characteristics in machining have certain degree of difficulty, and its strong tendency to strain hardening, when the deformation rate of 15%, about 18-8 double stainless steel. Hastelloy there in the sensitive zone, and its tendency to sensitization with the deformation rate increases. When the temperature is high, Hastelloy it easy to absorb the harmful elements of the mechanical properties and corrosion resistance decreased.
