Forged disk
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 disk is a type of the stainless steel sheets and plates that come in the form of a circle. YUHONG is a leading manufacturer and supplier of the forgings in different stainless steel grades and different dimensions.
