Product range

3-way pipe connector, stepped shaft, flanged shaft ,hydro turbine main shaft, crusher shaft ,roller press shaft, steel rollers , steel bushes, etc.

Free forgings means a processing technique to get the forgings with required shapes, dimensions and certain mechanical properties by exerting force on metals to let it deformed at any direction without any limitation .It mainly consist of upsetting , stretching, punching, hole expanding ,bending and twisting steps, Free forgings include shaft forgings, strip forgings, plate forgings, forged rings, barrel forgings, bowl-shaped forgings, etc.

We will draw up the manufacturing techniques to guarantee the production cycle and quality according to clients’requirement,

Materials

Various carbon steel ,carbon manganese steel ,alloy steel, stainless steel ,tool steela ,mold steels,and heat resistance steels ,like 25,35,45,55,16Mn,20Mn,40Mn,50Mn,20Mn5,28Mn6,

20SiMn,35SiMn,40Cr,25CrMo,35CrMo,42CrMo,20MnMoNb,20MnMo,20CrMnMo,20CrNiMo,F11,

F12,F22,F91,F92,17CrNiMo6,,18CrNiMo7-6,21CrMo10,34CrNiMo6,30CrNiMo8,34CrNi3Mo,34CrNi3MoV,5CrNiMo,5CrMnMo,60CrMnMo,55NiCrMoV7,AISI4340,H11,H13,70Cr3Mo,and 9Cr2Mo.

Quality Control

1. During smelting process,strict conrol is required both for the presribled elements(21CrMo10), and for some harmful elements and gas like P S Pb Sn As Sb Bi and H O N.
2. For pressure vessel with special requirement ,double vacuum smelting or electroslag remelting techniques are required to guarantee theirpurity ,chemical element,and gas content.
3. Strict forging techniques is required to meet the nondestructive testing requirement.
4. After heat treatment ,the free forgings possesshigh comprehensive mechanical properties, uniform structure,and large grain size .
5. CNC equipment is employed for finishing line to ensure the forgings precision.
6. All of the parameters of our custom forgings are in confirmity with national ,European ,and American standards, like JB/T6397, JB/T6908, JB/T1270, JB/T1271, JB/T5000, JB/T4730,GB/T6402,GB/T11880,GB/T17107,YB/T036,EN10228,EN10083,EN10250,EN10025,

   SEP1921,SEP1923,JISG3201,JISG4053,and ASTM,etc.
