Forging for shipbuilding

Forged crankshaft, Intermediate Shaft, Free forgings, Structural Ship Parts,

Quality control

  1. In the smelting process, to ensure the high purity and low gas content of raw material ,apart from the prescribed chemical elements, we have to strictly inspected some harmful elements such as P S Pb Sn As Sb and Bi,as well as some gas or non-metallic debris like H N and O
  2. Strict forging techniques are required to meet the nondestructive testing needs ,
  3. Heat treatment is needed to enhance the forgings’comprehensive mechanical properties; forgings for boats operating in ice-filled water are resistance to low-temperature impact.
  4. CNC equipment is employed for finishing line to ensure the forgings precision.
  5. For forgings parts with welding needs, we will adjust their chemical components to realize a reasonable carbon equivalent and enhance their performance.
