The world's third largest iron and steel company, Kobe Steel's product quality fraud scandal, intensified. Japanese media said on the 14th, involving counterfeiting problems increased to 13 kinds of products, the number of buyers affected by up to 500. In this long list of victims of the enterprise, you can find Mitsubishi Heavy Industries, Kawasaki Heavy Industries, Subaru, Ishikawajima Harima Heavy Industries Group and many other Japanese military enterprises, and they are the Japanese self-defense forces major equipment manufacturing enterprises.
Land: Armored artillery performance shrinks
Japan's news network said Kobe Steel for Japan's automotive, shipbuilding, aerospace and electronics and other industrial sectors to provide a large number of primary products, including iron, steel, aluminum products, copper products and even the use of LCD screen alloy materials used. For the SDF, the scandal brought about the most troublesome problem was "lagging effect", because these problematic steel and other primary materials were made as tank body, barrel and other finished products after the troops, not like Modular parts as "bad which cut which," only after the equipment out of the problem to find the crux.
In the case of the SDF, these inferior materials are most likely to lead to a sharp shrinking of the strength of armored and artillery units. In the past, the Japanese military industry chain is often only extended within the relevant enterprises, such as Mitsubishi Heavy Industries production of 90 main battle tanks, 89 infantry fighting vehicles and other self-defense armor weapons, usually only to the Group of Mitsubishi Steel, Mitsubishi Copper and other companies Buy raw materials. But in recent years the Japanese Ministry of Defense to open up the tender object, looking for more affordable raw material suppliers, Kobe Steel was able to cover the relevant areas.
Kobe Steel is good at smelting alloy steel, the industry said that the company's barrel chrome plating process is better than Mitsubishi steel counterparts, while the production of alloy steel armor also has an exclusive heat treatment process. According to reports, metallurgical business is the most common resort is to reduce the nickel, chromium, molybdenum and other expensive strategic precious metal formula content, and in high temperature refining process to reduce the cost.
But "fraud is easy to identify difficult", unless the SDF team of professionals to implement the "carpet-type investigation", otherwise it is difficult to easily determine what equipment in the end problems. Such as tanks and armored armor in the end is carburized surface hardened steel armor or ordinary armor, rely on the mass spectrometer to carefully screened. Can be equipped with the problem of armor, the future combat in the combat vehicle once hit by high-speed ammunition, armor even if not breakdown, but also a large area of crack, loss of protective effect.
The land self-defense force at the end of 2016 at the end of the Jiuzhu town in Tuen open activities, there have been 96-type wheeled armored vehicles wheel off the shaft accident, the armored vehicle earlier in Iraq, there have been suspected car roof cracks. The production of the car in Japan Komatsu production is Kobe Steel's long-term customers, which whether there is no association, with the "fake scandal" fermentation, the future will become the land self-defense team's heart disease.
Sea: submarine quality doubt
In the Maritime Self-Defense Force, Kobe Steel plays a particularly important role. Kawasaki Heavy Industries, Ishikawajima Seeding Heavy Industries and other Japanese warships construction giant on the extensive use of Kobe Steel provided by the metal products.
According to the Japanese "World Ship" disclosure, SDF ship steel, especially submarine steel, widely used in Kobe Steel provides high yield strength alloy steel. In particular, low-alloy, high-strength steels with a yield of 550 MPa and 690 MPa are manufactured by a special process of "Ni-Cr-Mo Quenching and Tempering Heat Treatment" held by Kobe Steel. However, in 2006, Japan "tide" submarine and Korean cargo ship collision accident, South Korea cargo ship leakage, and "Chao Chao" boat bow a huge dent. Compared to the previous US "Greenville" nuclear submarines and Japanese fishing practitioners collision accident, the Japanese ship was hit, the US submarine was a slight loss. The same is the submarine and the civil ship collision, the result is so different, can not help but let a lot of people doubt the Japanese submarine strong degree of flaws.
As for the copper and copper alloy materials, the Maritime Self-Defense Force used Kobe Steel products are also very impressive. Due to its good resistance to seawater corrosion, the SDV's propeller and power tank internal pipelines also make extensive use of copper and copper alloys, many of which are made of Kobe Steel's materials. Let the Japanese Self-Defense Force worry that the Japanese ship design habits in the structural strength of the redundancy do not do "extreme consideration", if Kobe Steel "by conscience" to do Seiko, it is not a big deal, but once it cut corners, direct The result is that the performance of ships is not up to standard.
Air: Missile missile electronics
Kobe Steel's problems also affect the Air Self-Defense Force. It is reported that the Ministry of Defense indirectly recognized the problems of Kobe steel products, aluminum products have been used in aircraft, missiles and electronic systems, but will not "immediately affect the use of".
According to reports, Kobe Steel for the Japanese fixed-wing aircraft, helicopters and missiles to provide fuselage aluminum frame, missile parts, etc., if the quality of defects, these high-value weapons, the right rate will undoubtedly greatly reduced. At present, the outside world is most concerned about the reliability of the Air Self Defense Force weapons. On October 5, the Self-Defense Force's F-15 fighter carried 99-type air-to-air missiles actually lost in the flight wing, and this in the air, "out of parts" things have occurred many times.
Experts in the evaluation, compared to aluminum products, the Air Self-Defense Force is more worried about Kobe Steel provided by the copper products in question, because in aircraft, helicopters, missiles and satellites, not only microelectronic control systems and instruments, instrumentation equipment to use copper, Many key components also use copper and copper alloys. For example, less than 11% tin is bronze pipe joints, "the main material", and manganese bronze to very high strength, tough, corrosion-resistant, is the aircraft landing gear and bracket "headed material."
In addition, the Air Self-Defense Force's missile engine combustion chamber and thrust chamber lining is also basically made of copper alloy, if there is shoddy situation, ranging from weapons failure, while the machine destroyed.
