RA330 alloy is a high-performance heat-resistant and corrosion-resistant material
RA330 is a high-performance heat-resistant and corrosion-resistant alloy, specially designed for working in high temperature and severe corrosive environments. The following is a comprehensive overview of RA330 alloy: Chemical composition: The main components of RA330 include chromium (about 14.00%~17.00%), nickel (33.00%~37.00%), carbon (≤0.15%), silicon (≤1.50%), manganese (≤2.00%), phosphorus (≤0.040%), sulfur (≤0.030%), etc. The combination of these elements gives RA330 excellent high temperature performance and corrosion resistance. Physical properties and characteristics: High temperature resistance: RA330 can maintain stability and strength at extremely high temperatures, with a maximum operating temperature of up to 1204°C (2200°F), and has excellent oxidation resistance. Corrosion resistance: It can still effectively resist various corrosive media at high temperatures, including acids, alkalis, salts, etc., especially suitable for environments containing sulfides. Mechanical properties: It maintains good strength and heat deformation resistance at high temperatures, and has excellent tensile and compressive resistance. Thermal conductivity: It has high thermal conductivity, which helps to dissipate heat quickly, and is suitable for manufacturing heat treatment equipment and heat exchangers. Application areas: Heat treatment industry: It is widely used in the manufacture of parts of heat treatment equipment such as furnace tanks, grates, conveyor belts, and radiant tubes. Chemical equipment: In chemical processing equipment,...
