NXF UNS N10276 2.4819/NiMo16Cr15W/C276 Length 1m-12m Diameter 1mm-1200mm Nickel Alloy Round Bar
Super alloys have good oxidation and creep resistance and can be strengthened by precipitation hardening, solid-solution hardening and work hardening methods. They can also function under high mechanical stress and high temperatures and also in places that require high surface stability. HASTELLOY(r) C276 is a wrought corrosion-resistant alloy that resists the development of grain boundary precipitates that degrade corrosion resistance.
The following datasheet provides an overview of HASTELLOY(r) C276.
C276 Nickel Alloy Round Bar Introduction
C276 Nickel Alloy Round Bar Product processing
1. Alloy Melting: Precisely mix steel, chromium, molybdenum, nickel and other metal raw materials according to the alloy grade, remove impurities, and then melt them in an electric arc furnace or a medium-frequency furnace at high temperature to fully blend the alloy elements, forming alloy steel liquid with uniform composition. Then, through the refining process, adjust the purity, remove bubbles and inclusions, ensuring the stability of the basic performance of the raw materials.
2. Casting Block Cutting: Pour the refined steel liquid into an alloy steel block. After cooling and solidification, heat it uniformly in a heating furnace, then use a preliminary rolling machine for cutting and rolling to break the loose structure of the steel block, compact the internal pores, and preliminarily regularize the shape of the bar billet, laying the foundation for subsequent fine processing.
3. Rolling, Cold Drawing and Forming: After secondary heating of the billet, perform hot rolling to form standard-sized round bar blanks, removing the surface oxide scale. For products with high precision requirements, conduct cold drawing processing. Through mold extrusion to calibrate the size, improve the roundness and straightness of the round bar, and make the surface smoother and more flat.
4. Heat Treatment and Quenching: The formed round bar undergoes quenching, tempering treatment, precisely controlling the temperature and duration to eliminate internal processing stress, significantly enhancing the strength, toughness and wear resistance of the round bar, avoiding deformation and cracking in the later use, and meeting the requirements of various working conditions.
5. Finishing Inspection and Storage: Finally, through fine grinding, polishing to remove surface defects, cut to the customized length, and then test the size accuracy, hardness, metallographic structure and other indicators one by one. Eliminate products， and after meeting the standards, pack and store.
