Compared with:2010, except for structural adjustment and editorial changes, the main technical changes are as follows:
a) Changed the names of some terms: "briquette" was changed to "powder metallurgy briquette", "pellet" was changed to "ball", "shot" was changed to "shot", "high nickel
Matte" changed to "nickel matte" "Bill" changed to "Rough" "Bill" changed to "Bill" "Slab" changed to "Slab" "Wire Billet (Wire
rod)" to "drawn billet (wire rod)" (see Chapter 3, Chapter 2 of the:2010 edition);
b) Changed the definitions of some terms: "alloy", "heat treatable alloy", "non heat treatable alloy", "nickel", "nickel alloy", "refined product"
"Blank", "cathode plate", "granule", "ball", "powder", "shot", "nickel smelting intermediate product", "nickel matte", "nickel oxide", "nickel oxide slag", "bar"
"Wire rod", "pipe", "thick plate", "thin plate", "strip", "round billet", "extrusion billet", "ingot", "slab", "drawing billet (wire bar)", "forging billet"
"Casting" (see Chapter 3, Chapter 2 of the:2010 edition);
c) The terms and definitions of "refined nickel", "flat sheet", "casting" and "melt" have been added (see Chapter 3):
