Overview
Forged disks are mainly used in fields such as petrochemical industry, pressure pipelines, pressure vessels, heavy machinery equipment, and mold industry. The maximum tonnage of cake shaped forgings can reach 6 tons, and the maximum diameter can reach φ 2500mm. The materials include carbon steel, alloy steel, low-temperature low alloy steel, stainless steel, duplex steel, etc. The material standards involve national standards, American standards, Ministry of Energy standards, etc. This product can choose different materials and processes according to the applicable location and performance requirements to meet various environments such as low temperature, high pressure, and corrosive media. Representative products such as various tube plates, flat covers, flange covers, tire mold bases, side plates, etc. required for heat exchangers, herringbone wheels for machine tools, idlers, eccentric bodies, steam turbine impellers, etc.
Stainless Steel 304 Forged Disk is a durable, corrosion-resistant, and high-strength component created through the forging process using 304 stainless steel. These disks are widely used in industries ranging from aerospace to automotive and marine due to their excellent properties, including high resistance to corrosion, ease of fabrication, and superior mechanical strength.
If you're considering using 304 stainless steel forged disks, it’s important to evaluate the specific application needs, including environmental conditions (e.g., exposure to chemicals or extreme temperatures) and mechanical load requirements.
