High Grade Special Steel Forging
Integral Forging Stabilizer

According to API Spec.7 and SY/T5144, drill collar is made of AISI 4145 modified chromium- molybdenum alloy steel. All threads are
phosphated, copperized or cold rolled .
SCOTON can offer kinds of stabilizer, such as  replaceable sleeve stabilizer, integral spiral
blade stabilizer, WZ type  integral blade
stabilizer, three roller stabilizer and non-magnetic stabilizer etc.


Mandrel bar

Our company is capable of producing a series of mandrel, such as MPM, PQF, FQM, with the diameter of Φ80-350mm, the length of
2500-17500mm, as a result of making the best use of our advantage in steel making, forging, heat treatment, machining plating
chromium adequately. The raw steel material is AISI H13 or 4CrMoSiV1, based on enterprise specifications.


Pipe Mould

Pipe mould, which was made from 21CrMo10 or 20-30CrMo, is the most important tool in the process of spheroidal cast iron pipe dies .
We provide many sizes of pipe mould the OD from DN80 to DN1200.


Main Shaft

Forgings for power station could meet JB/T standard or be produced according to the order. The main process is EBT +LF/VD(ESR)
melting + cogging down by hydraulic press + forming by rotary forging machines. The main products includes rotor for 25-200MW
steam turbine, rotary table and impeller for 25-200MW steam turbine, rotary forgings for 20-200MW steam tubine, large forgings for
hydrao turbine and turbine generator, shafts or axles for wlwctric motor, rotor and shaft for less than 25MW turbine. the delivery condition
could be machining or quenching and tempering.
