NS143

NS143 (NS1403) is a corrosion-resistant alloy with many excellent properties. It has good resistance to oxidation and moderate reductive corrosion, excellent resistance to stress corrosion cracking and good resistance to localized corrosion. It has satisfactory corrosion resistance in many chemical process media. NS143 (NS1403) corrosion resistant alloy applications. NS143 (NS1403) can be used in wet metallurgy and sulfuric acid industry equipment, etc. In the material field, it can be used to manufacture steel, forgings, strips, wire, bolts, nuts, etc.

Physical properties of NS143 (NS1403). Density 8.08 g/cm3 Melting point 1357-1430°C Density (room temperature): 0.292lb/in3 Poisson's ratio: 0.31 Modulus of elasticity (under tension): 28.0X103ksi Modulus of rigidity: 11.0X103ksi Specific heat (32-212°F): 0.12Btu/lb?°F Electrical resistance (room temperature): 651ohm-cir mil/ft Magnetic flux (annealed state): 1.002@200Oe In order to make the metal workpiece have the required mechanical, physical and chemical properties, in addition to the reasonable selection of materials and various forming processes, heat treatment process is often essential. Steel is the most widely used material in the mechanical industry, steel microstructure complex, can be controlled by heat treatment, so the heat treatment of steel is the main content of metal heat treatment. NS143 corrosion resistance: good corrosion resistance in concentrated sulfuric acid below 50 degrees, more than 50 degrees above Shanghai Yuan Ding is not recommended, in wet phosphoric acid, HCl is not an ideal choice of material, resistance to intergranular corrosion and pitting corrosion is not good.
