Classification
Hastelloy alloy is mainly divided into three series of B, C and G. It is mainly used in the case of iron-based Cr-Ni or Cr-Ni-Mo stainless steel, non-metallic materials and other strong corrosive media.
Hastelloy Grade Evolution
In order to improve the corrosion resistance and cold and hot processing properties of Hastelloy, Hastelloy has undergone three major improvements, and its development process is as follows:
B series: B → B-2 (00Ni70Mo28) → B-3
C series: C → C-276 (00Cr16Mo16W4) → C-4 (00Cr16Mo16) → C-22 (00Cr22Mo13W3) → C-2000 (00Cr20Mo16)
G series: G → G-3 (00Cr22Ni48Mo7Cu) → G-30 (00Cr30Ni48Mo7Cu)
C series: C → C-276 (00Cr16Mo16W4) → C-4 (00Cr16Mo16) → C-22 (00Cr22Mo13W3) → C-2000 (00Cr20Mo16)
G series: G → G-3 (00Cr22Ni48Mo7Cu) → G-30 (00Cr30Ni48Mo7Cu)
The most widely used are the second generation materials N10665 (B-2), N10276 (C-276), N06022 (C-22), N06455 (C-4) and N06985 (G-3).

Frequently Asked Questions (FAQ)
What makes Hastelloy C276 highly resistant to corrosion?
Hastelloy C276 features high levels of molybdenum and chromium, which provide superior resistance to chloride ion corrosion. The addition of tungsten further enhances its overall corrosion resistance in severe environments.
In which environments is Hastelloy C-276 preferred over standard stainless steel?
Hastelloy C-276 is one of the few materials that can withstand moisture chlorine, hypochlorite, and chlorine dioxide solutions. It is also highly resistant to strong oxidizing salt solutions like ferric chloride and copper chloride.
What are the primary differences between the B, C, and G Hastelloy series?
The B series (like B-2 and B-3) focuses heavily on nickel-molybdenum composition. The C series (like C-276 and C-22) adds chromium and tungsten for multi-media corrosion resistance. The G series (like G-3 and G-30) contains copper and higher chromium levels, making it excellent for phosphoric and acidic environments.
What surface finishes are available for stainless steel sheets?
Common surface finishes include 2B (smooth and moderately reflective), No.1 (hot-rolled, annealed, and pickled), No.4 (brushed finish), HL (hairline finish with continuous streaks), BA (bright annealed mirror-like finish), and 8K (highly reflective mirror finish).
Why is Chromium (Cr) a critical element in these alloys?
Chromium is essential because it increases the hardness, tensile strength, and toughness of the metal while providing the primary mechanism for anti-wear and corrosion resistance by forming a passive oxide layer.
What standards and sizes do your stainless steel sheets conform to?
Our stainless steel sheets conform to major international standards including ASTM, AISI, SUS, JIS, EN, DIN, BS, and GB. They are available in thicknesses from 0.3mm to 120mm, widths from 1000mm to 2000mm, and customizable lengths.
