uns n08020 material chemical composition

The core element composition of Alloy 20 includes nickel (32% -38%), chromium (19% -21%), molybdenum (2% -3%), copper (3% -4%), as well as small amounts of carbon (≤ 0.07%), manganese (≤ 2.0%), silicon (≤ 1.0%), and trace amounts of niobium (0.8% -1.2%).

uns n08020 astm Mechanical properties

The tensile strength at room temperature is 550-750MPa, the yield strength is ≥ 240MPa, the elongation rate is ≥ 30%, the cross-sectional shrinkage rate is ≥ 50%, it has good plasticity and toughness, and can withstand bending, stamping and other forming processes.

carpenter 20 material Corrosion resistance

Alloy N08020 Pipe has excellent corrosion resistance to sulfuric acid, phosphoric acid, mixed acids of nitric acid and sulfuric acid, organic acids (such as acetic acid, citric acid), chloride solutions, etc. Especially in medium concentration sulfuric acid (5% -45%) and corrosive environments containing chloride ions, it performs better than ordinary stainless steels such as 304 and 316.

carpenter 20cb3 Temperature applicable range

Long term use temperature ranges from -29 ℃ to 427 ℃. Within this range, the mechanical and corrosion resistance properties remain stable, which can meet the usage requirements under normal and medium temperature conditions.

b462 n08020 Welding performance

Alloy N08020 Pipe has good welding performance, using matching alloy welding rods (such as ERNiCrMo-3), by reasonably controlling the welding temperature (avoiding exceeding 1065 ℃) and cooling rate, intergranular corrosion in the heat affected zone can be avoided, and the strength and corrosion resistance of the welded joint are close to those of the base material.
