Products Description
1.Product features
1.1 Perfect combination of high strength and low density
The most attractive feature of GR12 alloy is its excellent strength-to-weight ratio. Compared to steel, titanium alloys are much less dense, about 60% of steel. Its strength, however, approaches or exceeds that of some high-strength steels. This property makes GR12 an ideal material for aerospace and military applications, especially where weight reduction is required while ensuring high strength.
1.2 Good fatigue resistance
Another major advantage of GR12 alloy is its good fatigue resistance. Fatigue damage is a common form of damage to metal materials under long-term stress or alternating loads.GR12 titanium forged rings have excellent fatigue resistance, which can maintain stable mechanical properties and reduce failures under long-time working loads. This characteristic makes GR12 widely used in high-end equipment, especially under high load conditions.
2.Forging process
2.1 The blank of forging cake ring must be disc sawing, after sawing, it must be chamfered with flat head, chamfering 15～20×45°.
2.2 Strictly implement the process card upsetting deformation, upsetting, must remember the original axial and radial, to ensure that the last back to the original axial, to ensure the correctness of the flow. Observe diligently when upsetting, and correct the distortion in time to prevent folding.
2.3 Cake material is based on the requirements of the process card after upsetting, and finally after heating and shaping to become the required size of cake material, and its tolerance according to the requirements of the process card.
2.4 The deformation process of ring material is that the blank is first heated and then upsetting and punching, and then heated for reaming or elongation (developed on the process).
2.5 When punching, the punch should be aligned with the centre to prevent the punch from deviation. Punching head is generally punched into the blank height of 7/10 or so is appropriate, conducive to turning the punch out of the residual material.
2.6 Reaming method: In general, the mandrel is used to ream the hole, but sometimes the punch is also used to ream the hole. Reaming mandrels do not choose too small, otherwise, the inner hole caused by the plum-shaped indentation, just to be able to penetrate as good, every fire can be replaced according to the situation of the mandrel. The method of pulling long: the use of mandrels plus wrestling. For alloy material, while the material temperature is high, the first two ends to the size of the pull, in order to prevent the two heads cool down quickly and cracks caused by scrapping.
3.Application Fields
Aerospace, aviation, military, light industry, chemical industry, textile, medical and petrochemical fields.
