Hastelloy C276 ASTM Standard B575 Plate is a nickel-molybdenum-chromium superalloy with an enhancement of tungsten made to have superb deterioration resistance in a wide variety of extreme atmospheres. Although there are a number of variations of the nickel alloy, Hastelloy C276 Plate is without a doubt the most commonly used.
Hastelloy C276 Plate shows superb deterioration resistance in a range of extreme settings and also media. Like lots of other nickel alloys, it is pliable, easily developed and also welded.
ASTM B575 UNS N10276 Hastelloy C276 Sheet is frequently utilized in several industries, consisting of petrochemical, chemical oil and gas, power generation, pharmaceutical, pulp and paper manufacturing and drainage treatment. Hastelloy C276 Coil has superior resistance to matching, tension deterioration breaking as well as oxidizing environments.
ASME SB 575 UNS N10276 material likewise displays resistance to deterioration by salt water in crevice conditions, which can generate hostile attack in other commonly utilized materials. UNS N10276 Plate is usually remedy heat-treated at 2050 Degree F and fast quenched.
The only difference in between Alloy C276 sheet as well as plate steel is the gauge (thickness) of the metal. ASTM B575 UNS N10276 Sheet as well as Hastelloy Alloy C276 Plate are words utilized to explain the category of metal depending upon its thickness. While sheet steel is less than 3 mm thick, plate steel is certainly thicker than 3 mm.

What is the main application of Hastelloy C276 Plate?
Hastelloy C276 is widely used in the petrochemical, chemical processing, power generation, and pharmaceutical industries due to its excellent resistance to aggressive chemicals and extreme environments.
How do ASTM B575 standards define Hastelloy C276?
ASTM B575 is the standard specification for low-carbon nickel-chromium-molybdenum alloy plate, sheet, and strip, ensuring consistent quality and performance for materials like UNS N10276.
What makes Hastelloy C276 resistant to corrosion during welding?
The alloy's very low carbon content minimizes grain-boundary carbide precipitation during the welding process, which helps maintain its superior corrosion resistance in the heat-affected zones of welded joints.
Can Hastelloy C276 withstand wet chlorine gas?
Yes, it is one of the few materials that can effectively withstand the highly corrosive effects of wet chlorine gas, as well as hypochlorite and chlorine dioxide solutions.
What is the difference between C276 sheet and plate?
The primary difference is the thickness: "sheet" typically refers to metal less than 3 mm thick, while "plate" refers to metal thicker than 3 mm.
Does this alloy perform well in seawater?
Yes, UNS N10276 exhibits exceptional resistance to corrosion by salt water, especially in crevice conditions where other materials often fail.
