Hot Sale ASTM B619 B622 B474 B626 N10276 2.4819 Alloy C-276 Hastelloy C276 Welded Seamless Pipe Tube Price Per Kg

Hastelloy C276 tube alloy is a nickel-chromium-molybdenum containing tungsten alloy with low carbon and silicon content. It is regarded as a universal corrosion resistant alloy, mainly resistant to wet chlorine, various oxidation resistance chloride chlorate solutions of sulfuric acid and oxidizing salts. It has good corrosion resistance in both low temperature and high temperature hydrochloric acid environments. For nearly thirty years, it has been widely applied in harsh corrosive environments such as chemical petrochemical, flue gas desulfurization, pulp and paper, and environmental protection industries.

Applications:

• Petrochemical equipment
• Heat exchangers
• Flue gas desulfurization equipment
• Fluid chemical pumps
• Fluorine chemical applications

Key Properties:

• Excellent corrosion resistance to most corrosive media in oxidation and reduction atmospheres
• Good crevice corrosion, pitting corrosion and stress corrosion resistance
• High Mo content provides resistance to chlorine ion corrosion
• W elements further improve corrosion resistance
• One of the few materials resistant to wet chlorine, chlorine dioxide, and hypochlorite solutions
• Significant corrosion resistance to high concentration chlorate solutions like ferric chloride and copper chloride
• Suitable for various concentration sulfuric acid solutions

Mechanical Properties:

Tensile strength: σb≥730Mpa, Elongation: δ≥40%, Hardness: HRB≤100.

Hastelloy C-276 alloy thermoforming is immediately annealed and quenched with water at 1150℃. Cold deformation increases its strength. The formability is similar to common austenitic stainless steel but with greater strength, resulting in higher stress during cold forming and faster work hardening rate. Midway annealing treatment is recommended during extensive cold forming processes.
