ASTM DIN Standard Forged Steel Ring UT Magnetic Particle Inspection


With max unit weight 12ton and max outer diameter 300mm we are able to manufacture kinds of 

ringlike&cylindrical forgings including non-standard flanges, wind power flanges, gear rims, 

wind power main shafts, etc. Which are extensively applied in Industries of petroleum, machinery, 

engineering, harbor machinery, gear, reducer machinery, hydraulic machinery and wind 

generating set etc. 
 (1). Among the free forgings carbon steel forgings are generally the better choice for the sake
 of its high tolerance strength, hardness, yield strength, elongation, crush resistance, torsion 
 resistance and shearing resistance. 
 (2). We can forge forgings according to weight ranges from 100kg-12T
 (3). They are mainly applied in machinery, chemical and petroleum industries, mould, shipping, 
 transportation, agriculture, pipeline, metallurgy, GI, etc.
 (4). We have professional UT center and every year we have less than 2 complaint cases from 
 customers and products qualification rate over 99%. 
 (5). We were certificated to ISO9001: 2008 and passed 9 countries' authentication of 
 "Classification Society". 
 (6). We usualy use material of steel type of GB, ASTM, AISI, ASME, DIN, BS, EN, etc. According
 to customers' different requirements.
 (7). Main material are CK45, AISI 4140&4130, 5CrMnMo, 40Cr, 42CrMo, 20Cr2Ni4, 5CrNiMo, 
 15CrNiMo, 20CrNiMo, 35CrMo, 40CrNiMo, etc. 
 (8). Regularly, we accept processing on giving materials. 
 (9). We generally produce forging blank with rough machining range from 150kg to 20t.
 (10). According to practical situation and customers' clear requirements we can render 
 excellent heat treatment. 
 (11). As for the third party inspection, we will try out utmost to satisfy our customers' request. 
 (12). If you have office in China, pls kindly pay a visit to our factory, and we are with much 
 pleasure to apply for the invitation letter for your visa. 
 (13). Our staff are with tremendous sincerity welcome your arrival and guide!

1. Any striking on and collision with roll rings is strictly prohibited.
2. When installing the whole assembly of roll rings, the clearance of the
bearings in relation to the casings should be on the tighter side .
3. The precision of rotation of the whole assembly ( circular runout and end runout )
should be kept within ±0.05mm.
4. The fitting -in of the whole assembly and the roll rings shall be a transitional fitting -in and fastened.
5. The roll rings should not be cooled by water or oil water emulsion.
6. The joints of the pipes in the internal cooling system should not be leaky and it is     advisable that no cooling is applied.

Competitive Advantage:

1. Much experiencing in forging part

2. Disciplined staffs and scientific operation;

3. Product performance;

4. Advanced produce and inspecting equipments;

We cordially look forward to serving you with our best goods and service!

We have three factories directly (steel plant, forging plant, machine processing factory), control

the entire production process, greatly reduce the production cost and circulation costs, can

provide cheap and fine products to our customers.





Typical problems associated with metal rings can frequently be traced to the metalforming process. Cast rings are often plagued with substandard strength and integrity. Rolled and welded or cut rings from plate are susceptible to fatigue, and carry excess material and processing costs. In the cases below, these common problems were solved by switching to the forging process.

Services Team is ready to assist you in meeting your design challenges and program objectives with clear communications on everything from order status to milestone achievements.
