Hastelloy B-2( W.Nr.2.46,NiMo28,UNS N10665)
Corrosion resistant alloy:  Hastelloy B-2

Hastelloy B-2 alloy equal material:
  Germany grade:  W.Nr.2.46  DIN grade:  NiMo28  American grade: UNS N10665  ISO grade:  NiMo28

Hastelloy B-2 alloy steel Characteristic :
  1.control iron and chromium in the lowest content, prevent the generation of β phase Ni4Mo28
  2.The excellent corrosion resistance to reduction environment.Sulfuric acid anti medium  concentration
  3 excellent non oxidative acid corrosion
  4.very good resistance to chloride ion reduction to stress corrosion cracking (SCC)
  5.Capacity of excellent resistance to various organic acid corrosion

Hastelloy B-2 Corrosion resistant alloy steel Property ：

  Hastelloy B-2 steel material  density: 8.9g/cm3

  Hastelloy B-2 steel material   Melting temperature range: 1330-1380 degree

Hastelloy B-2 alloy steel Processing and heat treatment：
  1.Should be quickly heated to a required temperature. The temperature range of 1160 - 900 degree heat processing.
  2.The degree of deformation, the alloy grain size and forging the final forging temperature is closely related to.
  3.Welding slag surrounding oxide, alloy surface oxide color and weld attachment than stainless steel, grinding and recommend the use of fine grain or fine grain grinding wheel abrasive belt.
  4.Alloy should be machined after annealing, due to the work hardening material rate is higher, it should adopt the cutting speed than standard austenitic stainless steel low alloy processing low and heavy feed processing, can cut into the cold work hardening of the surface below.

Hastelloy B-2 alloy steel application:
  1. manufacturing work under high temperature bolt; gas turbine rotor blades, impeller and other structural parts;
  2. rocket engine thrust chamber;Reverse thrust device
  3. on the plane;
  4. large high pressure vessel;
  5.The elastic gas seal, sealing sheet, rubber machinery electric blade.
Key words:  Hastelloy B-2 stock,  Hastelloy B-2 competitive price,  Hastelloy B-2  high quality,  Hastelloy B-2 supplier,  Hastelloy B-2 manufacturer.
