Tungsten carbide welding bars are commonly used in the oil and gas industry for various applications. These bars are made from a combination of tungsten and carbon, which results in a very hard and wear-resistant material.

Kazuaki Kama, president of the Japan Shipbuilding Association, plans to ask steel mills to lower the price of ship plates when meeting with Eiji Hayashida, chairman of the Japan Steel Association. In terms of price, the price of ship plates ordered by Japan, the world's third-largest shipbuilding country, to domestic steel mills is 30% higher than that of South Korea.
The appreciation of the yen has made the ship plates produced in Japan uncompetitive in foreign markets. The Japan Shipbuilding Association, which includes Mitsubishi Heavy Industries and Ishikawajima Heavy Industries, is working with Japanese auto companies to evaluate the cost and price of steel. Only by negotiating, Japanese steelmakers – Japan’s largest steel company – Nippon Steel and JFE Holdings will not hand over the contract to South Korea’s Posco and China’s Baoshan Iron and Steel.
Naoki Iizuka, senior economist at Mizuho Securities in Tokyo, pointed out that “the relationship between Japanese steel suppliers and users has become more and more commercial, unlike the relationship between them in the past. Japan’s industries are undermining costs. Pressure to compete with the world."
Japanese shipyards will negotiate price separately with shipboard suppliers. The Japanese shipbuilding industry's demand for lowering the price of shipboards is due to the fact that domestic shipyards are unable to obtain shipboard supplies for decades, while Japanese shipboard suppliers are providing shipboards to foreign users at lower prices. Since Japanese shipboard prices are higher than those of South Korea and China, Japanese steel companies have lost their competitiveness with domestic shipyards, which has further affected the domestic steel industry to receive new orders.
According to a 19-member shipbuilding group closely controlled by Imabari Marine, the ship's board accounts for about 40% of the shipbuilding cost. In the first half of this year, orders received by Japanese shipyards accounted for 12.01% of the total orders received by shipyards worldwide, down 2.4% from 2010. Orders received by Korean shipyards increased by 23% to 56.4%.
After the price of iron ore and coking coal soared faster than the yen, the Japanese steel company, the world's second-largest steel producer, is under pressure to pass on raw material costs to users and profit. During the June-September quarter, the daily profit of Nippon Steel has dropped from 13.62% a year ago to 12.24%.
In response, the Japanese Shipbuilding Association spokesman Yasumi Makimura said that he is not willing to comment. Nippon Steel spokesman Hiroshi Nakashima is also reluctant to comment on the ship board price negotiations alone. But JFE Holdings said that if the price of raw materials rises above its digestive capacity, the company will require its users to share the cost.
In March of this year, Posco, the largest steel company in South Korea, increased its annual flat-panel production capacity by 40% to an annual output of 7 million tons, exceeding the annual production capacity of JFE Steel and becoming the world's largest shipboard manufacturer. . Hyundai Steel said that in July, the company expects to receive at least 10,000 tons of ship orders from Japanese shipbuilding companies in the second half of this year.
According to statistics released by the Japan Steel Association, Japan imported 233,000 tons of ship plates in 2010, equivalent to 2.6% of the ship plates produced by Japanese steel mills for Japanese users.
1. Hardfacing: Tungsten carbide welding bars are used for hardfacing applications, where a wear-resistant layer is applied to drilling tools, valves, pumps, and other equipment exposed to abrasive environments. This helps to extend the lifespan of the components and reduce maintenance costs.
2. Drill bits: Tungsten carbide welding bars are used to manufacture drill bits for oil and gas exploration. The hard and durable nature of tungsten carbide makes it ideal for drilling through tough rock formations.
3. Wear plates and liners: Tungsten carbide welding bars are used to create wear plates and liners for equipment used in oil and gas production. These plates and liners protect the underlying metal surfaces from abrasion and corrosion, ensuring the longevity of the equipment.
4. Valve seats and seals: Tungsten carbide welding bars are used to manufacture valve seats and seals for oil and gas valves. The high hardness and wear resistance of tungsten carbide ensure reliable sealing and prevent leakage in critical applications.
5. Downhole tools: Tungsten carbide welding bars are used in the manufacturing of downhole tools such as stabilizers, reamers, and drill collars. These tools are subjected to high pressures, temperatures, and abrasive conditions, and tungsten carbide helps to enhance their durability and performance.
Overall, tungsten carbide welding bars play a crucial role in the oil and gas industry by providing wear resistance, hardness, and durability to various components and equipment.
Due to the appreciation of the yen, Japanese shipyards will require Japanese steel mills to reduce the price of ship plates, otherwise they will use the ship plates imported from South Korea and China instead. This is revealed by three people familiar with the Japanese shipyard's request for steel mills to reduce ship price negotiations.
