5, Functional advantages and characteristics

Corrosion resistance: Titanium forgings have good corrosion resistance and can maintain durability in various acid, alkali, salt and other environments.

High strength: Titanium forgings have high strength and hardness, and are more durable than forgings of other materials.

Anti-fatigue: Titanium forgings have strong resistance to fatigue and long service life.

Quality and easy processing: Compared with other forgings, titanium forgings are lighter in weight, easy to transport and install, and are also easy to process into various shapes.

Good biocompatibility: Titanium forgings have good biocompatibility, no obvious stimulation and rejection to human tissues, and are widely used in the field of medical equipment manufacturing.

6, Application and other precautions

Application: Titanium forgings are widely used in aerospace, shipbuilding, chemical industry, electronics, medical equipment and other fields. Such as engine blades, ship propellers, chemical containers, seamless pipes, medical implants, etc.

Precautions:

(1) When purchasing titanium forgings, it is necessary to carefully check the product quality and material qualification certificates and other information, and ensure that they comply with relevant standards and specifications.

(2) When processing and using titanium forgings, attention should be paid to the requirements of the environment and medium to avoid problems such as oxidation or hardening caused by excessive fastening and contact.

(3) During the welding operation, avoid oxidation, pollution and other phenomena as much as possible to ensure the welding quality.

In summary, titanium forgings have excellent properties such as high strength, corrosion resistance, and oxidation resistance, and are widely used in many fields. When using titanium forgings, attention should be paid to the requirements of relevant standards and specifications to ensure product quality and safety.
