Dingding Titanium Industry: A corrosion-resistant high-strength titanium alloy solution for the shipbuilding and military industry

Ship military equipment has long faced the triple test of "strong seawater corrosion, complex stress impact, and high concealment requirements", and material performance directly determines the combat effectiveness and service life of the equipment. Baoding Dingding Titanium Products Co., Ltd. relies on the industrial advantages of "China Titanium City" and military grade production qualifications, with GJB standards as the core, to develop and produce ship specific titanium alloy rods, plates, wires and other products, which are widely used in key parts such as ship structures, power systems, weapons and equipment, and have become a reliable material supplier for ship military units.

1、 Focusing on three core ship scenarios, accurately solving military pain points

To meet the demands of the frontline of shipbuilding and military industries, customized titanium alloy solutions with "corrosion resistance, high strength, and lightweight" are tailored to meet the stringent working conditions of different parts, accurately matching the performance requirements of equipment.

1. Titanium alloy for ship hull and structural components: dual protection of corrosion resistance and impact resistance

Structural components such as ship hulls, decks, and cabin frames are immersed in seawater with a salt content of 3.5% for a long time, facing two core pain points: electrochemical corrosion and wave impact fatigue. Traditional steel requires frequent rust removal and maintenance, which seriously affects the combat readiness. Dingding Titanium Industry provides exclusive solutions based on ship specific titanium alloys such as TA10, TC4, Ti-6Al-4V, etc

The TC4 titanium alloy plate produced by the "high-purity sponge titanium+vacuum consumable melting" process has a corrosion rate as low as 0.002mm/year in artificial seawater, which is 1/50 of stainless steel. It can achieve "15 year maintenance free" ship structural components and significantly reduce logistics support costs. In response to the wave impact and collision stress borne by the hull, the customized TC4 titanium alloy rod has a tensile strength of 960MPa, a yield strength of ≥ 870MPa, an elongation rate of over 14%, and a stable impact toughness of over 75J/cm ² in the seawater temperature range of -20 ℃ to 60 ℃, avoiding the risk of low-temperature brittle fracture.

We can customize titanium alloy plates with a thickness of 3-80mm and titanium alloy rods with a diameter of 8-300mm according to the tonnage and structural requirements of the ship. The dimensional tolerance is controlled within ± 0.04mm, and it supports complex surface forming and welding processing. It has been applied to key structures such as small frigate decks and submarine cabin frames.

2. Titanium alloy for ship power and transmission systems: both high temperature resistance and high wear resistance

Power components such as ship diesel engine pistons, gas turbine blades, and transmission shafts are prone to wear and tear, corrosion, and leakage when working in environments with high temperatures (200-500 ℃), high loads, and seawater steam corrosion, which directly affects the stability of power output. Dingding Titanium Industry's targeted research and development of high-temperature resistant titanium alloy products such as TC11 and Ti-6242 accurately solves pain points:

Through the optimization of the "electric slag remelting+isothermal forging" process, the tensile strength of titanium alloy remains above 850MPa at a high temperature of 500 ℃, the high-temperature hardness reaches HV350, and the wear resistance is improved by 50% compared to ordinary titanium alloy, which can extend the service life of the transmission shaft to more than 8000 hours. In response to the sealing requirements of the power system, the welding strength of the titanium alloy wire produced reaches 98% of the base material, and the sealing leakage rate is less than 1 × 10 ^ -10 Pa · m ³/s in seawater steam environment, which meets the strict sealing standards of ship power systems.

3. Titanium alloy for ship weapons and electronic equipment: lightweight and stealth synergy

Weapon electronic components such as ship missile launchers, radar antenna covers, and sonar shells require both "lightweight and weight reduction" to enhance ship maneuverability, as well as "non-magnetic and anti-interference" to ensure equipment concealment and detection accuracy. This is the core concern of ship military customers. Dingding Titanium Industry's solution is as follows:

The customized TA7 titanium plate has a specific strength twice that of high-strength steel, and can achieve a weight reduction of 40% when used for missile launchers, reducing the center of gravity of ships and improving navigation stability. The non-magnetic titanium alloy product developed for radar antenna covers has a magnetic permeability of ≤ 1.004, which avoids interference with electronic signals and has excellent electromagnetic wave penetration, ensuring a radar detection range increase of more than 15%.

After surface sandblasting treatment, the special titanium alloy for sonar shell has a sound impedance matching degree of 95% with seawater, reducing sound wave reflection and attenuation and improving sonar detection accuracy; Under a pressure environment of 1000 meters in the deep sea, the compressive strength of the material remains at 1200 MPa, with no risk of deformation or cracking, ensuring the stable operation of sonar equipment.

2、 Four major military grade advantages, building a solid foundation of cooperation and trust
