Metallographic structure
Hastelloy B-2 has a face-centered cubic lattice structure. By controlling the content of iron and chromium at the minimum value, the processing brittleness was reduced and the precipitation of Ni4Mo phase was prevented at 700-870 C.
Technological Performance and Requirements
1. Hastelloy B-2 should be heated as fast as possible to the required temperature. The hot working temperature range is 1160 ~900 C.
2. The average grain size of Hastelloy B-2 alloy is closely related to the degree of deformation and the final forging temperature.
3. The adhesion of oxide, oxidation color and welding slag around the weld seam of Hastelloy B-2 alloy is stronger than that of stainless steel. Fine grain abrasive belt or fine grain grinding wheel is recommended for grinding.
4. Hastelloy B-2 alloy should be machined after annealing. Because of its high work hardening rate, it is advisable to use a lower cutting speed and a progressive knife than standard austenitic stainless steel with low alloy to cut into the surface of cold work hardening.
Characteristic
Hastelloy B-2 has excellent corrosion resistance to hydrochloric acid at all concentrations and temperatures, as well as to reducing environments such as sulphuric acid, phosphoric acid, acetic acid and other non-oxidizing media. It can also resist pitting corrosion, stress corrosion cracking, edge and welding heat affected zone corrosion. Like Hastelloy B, Hastelloy B-2 is highly susceptible to oxidation and therefore cannot be used in environments containing iron or copper salts because these substances can cause corrosion rapidly.

Stainless steel sheet surface finish characteristics
2B |
The surface brightness and flatness of no2B is better than no2D. then through a special surface treatment to improve its mechanical properties,No2B could nearly satisfy comprehensive uses. |
No.1 |
Polished with abrasive belt of grit#100-#200, have better brightness with discontinuous coarse stria, used as inner and external ornaments for building, electrical appliances and kitchen utensils etc |
No.4 |
Polished with abrasive belt of grit #150-#180,have better brightness with discontinuous coarse stria, but thinner than No3, are used as bathtub buildings inner and external ornaments electrical appliances kitchen utensils and food processing equipment etc. |
HL |
Polished with abrasive belt of grit #150-#320 on the NO.4 finish and has continuous streaks, mainly used as buildings ornaments elevators, door of building, frontal plate etc. |
BA |
Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror, kitchen apparatus, ornament etc. |
8K |
The product have excellent brightness and prefer reflexivity can to be the mirror. |
Stainless steel Sheets Maintenance:
(1) Regular cleaning and maintenance
(2) Pay attention to prevent the occurrence of the phenomenon of surface scratches
(3) Use soap, weak detergent or warm water to remove surface dust, dirt
(4) In addition to the surface of the binder with alcohol or an organic solvent (ether, benzene)
(5) Use neutral detergent or ammonia solution in addition to surface oil
(6) With 10% nitric acid or abrasive detergent in addition to the surface of the embroider caused by the dirt.
