Frequently Asked Questions
Q1: What are the primary application areas for Hastelloy plates?
Hastelloy plates are widely utilized in demanding environments including heat exchangers, bellows compensators, chemical equipment, flue gas desulfurization and denitrification systems, the paper industry, aerospace applications, and various highly acidic environments.
Q2: Why is Hastelloy C-276 highly resistant to corrosion?
Hastelloy C-276 features high molybdenum and chromium contents which protect the alloy from chloride ion corrosion. The addition of tungsten further enhances its overall corrosion resistance, making it one of the few materials capable of resisting moisture chlorine, hypochlorite, and chlorine dioxide solutions.
Q3: How are Hastelloy alloys classified?
Hastelloy alloys are classified into three primary series: B series (such as B, B-2, B-3), C series (such as C, C-276, C-4, C-22, C-2000), and G series (such as G, G-3, G-30). They are mainly applied where traditional iron-based stainless steels are insufficient against strong corrosive media.
Q4: What surface finishes are available for stainless steel sheets and their uses?
Common surface finishes include 2B (general usage with good flatness), No.1 (coarse stria for building ornaments), No.4 (thinner stria for kitchen utensils and food equipment), HL/Hairline (continuous streaks for elevators and doors), BA (bright annealed mirror-like finish), and 8K (highly reflective mirror finish).
Q5: How does the chemical composition affect the performance of stainless steel?
Different elements impart specific properties: Carbon increases hardness and wear resistance; Chromium improves tensile strength and anti-corrosion; Nickel enhances strength and overall corrosion resistance; Molybdenum improves machinability; and Tungsten increases hardness and toughness.
