1. Alloy 20 (N08020) alloy nickel-based alloy density: 8.08 g/cm3,
2. Alloy 20 (N08020) alloy nickel-based alloy melting point: 1357-1430℃.
Alloy 20 (N08020) nickel-based alloy mechanical properties:
1. Alloy 20 (N08020) alloy tensile strength (MPA) Rm N/mm2 ≥ 620,
2. Alloy 20 (N08020) alloy yield strength (MPA) RP0.2N/mm2 ≥ 300,
3. Alloy 20 (N08020) alloy elongation A5 % ≥ 40.
Alloy 20 (N08020) nickel-based alloy phase structure: Alloy 20 (N08020) nickel-based alloy is treated at 1120℃ for 2h, and only TiN nitride and Cr7C3 type carbide are present. After long-term aging at 870℃ and 1500℃, the organization is still Cr7C3 and TiN, indicating that the organization of the alloy is stable.
Alloy 20 (N08020) nickel-based alloy process performance and requirements:
1. Alloy 20 (N08020) nickel-based alloy has good hot working performance, and the heating temperature of the steel ingot forging is 1110℃～1140℃. The average grain size of the alloy is closely related to the deformation degree and final forging temperature of the forging.
2. Alloy 20 (N08020) nickel-based alloy has good welding performance and can be connected by various methods such as arc welding, argon arc welding, resistance welding and brazing. Large or complex welded structures should be annealed at 870℃ for 1h after fusion welding to eliminate welding stress.
3. Alloy 20 (N08020) nickel-based alloy must be machined after heat treatment. Due to the work hardening of the material, it is advisable to use a lower cutting speed and heavy feed than the processing of low-alloy standard austenitic stainless steel to machine into the surface layer that has been cold-worked and hardened.
Alloy 20 (Alloy 20) is an iron-based austenitic alloy developed to resist sulfuric acid corrosion. It has excellent resistance to sulfuric acid corrosion; it has strong resistance to chloride stress corrosion, pitting corrosion and crevice corrosion in phosphoric acid, nitric acid and chloride environments. Therefore, Alloy 20 is also known as a corrosion-resistant alloy; it has a wide range of applications: such as: chemistry, food, medicine, power production and plastics industry. Resist pitting and chloride corrosion, stress corrosion cracking problems, etc.
