1. Question: What are the main differences between Hastelloy C276, Inconel, and stainless steel plates?
Answer: Hastelloy C276 is a nickel-molybdenum-chromium alloy with excellent resistance to oxidizing and reducing environments, ideal for chemical and petrochemical applications. Inconel is a nickel-chromium-based superalloy with high strength and oxidation resistance at elevated temperatures. Stainless steel plates (210, 304, 316, 316L, 309, 310, 310S) offer good corrosion resistance and mechanical strength for general industrial and construction applications, with 316/316L particularly resistant to chlorides and 309/310/310S suitable for high-temperature service.
2. Question: What applications are these corrosion-resistant steel plates suitable for?
Answer: These plates are suitable for chemical processing equipment, heat exchangers, boiler components, marine and offshore structures, food processing, and high-temperature industrial equipment. Hastelloy C276 and Inconel are preferred in highly corrosive or high-temperature environments, while stainless steel is suitable for moderate corrosion and temperature conditions.
3. Question: What thicknesses and sizes are available for these plates?
Answer: Plates are available in a wide range of thicknesses, typically from 1mm to 200mm, and in standard widths and lengths (e.g., 1000mm–3000mm width, 2000mm–12000mm length). Custom sizes can also be produced according to project requirements.
4. Question: How resistant are these plates to corrosion and high temperatures?
Answer: Hastelloy C276 exhibits outstanding resistance to oxidizing and reducing agents, acids, and chlorides, with excellent durability in chemical environments. Inconel maintains mechanical strength and oxidation resistance at temperatures up to 980°C (1800°F). Stainless steel 316/316L offers good resistance to chloride-induced corrosion, and 309/310/310S plates are suitable for high-temperature oxidation environments up to 1000°C.
5. Question: What surface finishes and testing options are available for these plates?
Answer: Plates can be supplied in mill finish, ground, polished, pickled and passivated, or custom surface finishes. Testing options include chemical composition analysis, mechanical testing (tensile, hardness), non-destructive testing (ultrasonic, radiographic), and certifications according to ASTM, ASME, or GB/T standards.
