Strong market demand for fasteners

Strong market demand for fasteners In 2012, the fastener industry presented the situation of “first low, then high, and then new high”. Since the third quarter of this year, with the convening of the 18th CPC National Congress, a series of new policies have been introduced, relying on key industries such as autos, railways, ships, aerospace, infrastructure, energy industry, domestic appliance market and information, etc. The firmware market will usher in a new wave of technological innovation and promote the healthy development of the entire fastener industry.

By the end of 2015, China's auto industry will have an average annual sales volume of 23 million vehicles. The annual demand for automotive fasteners will exceed 1.5 million tons.

During the 12th Five-Year Plan period, China will build 56 new airports. Airbus and Boeing also announced plans to speed up development. There will be 400,000 fasteners on the fuselage and wings of a two-aisle aircraft.

The new energy industry - as one of the strategic emerging industries for the country to speed up cultivation and development, has entered the fast lane of development. The state plans to build wind turbines with an installed capacity of 70 million kilowatts by 2015, and use more than 500,000 tons of high-strength fasteners for annual wind power; and start construction of more than 40 million kilowatts of nuclear power units by 2020, and special fasteners and special-purposes for high-strength nuclear power. The annual demand for materials fasteners and welding rivets is more than 8-10 million tons. At the same time, the annual demand for fasteners in the construction and maintenance of high-voltage and ultra-high voltage transmission towers is nearly 220,000 tons.

In addition, the country’s demand for fasteners in agricultural machinery, construction machinery, and railways cannot be underestimated. During the 12th Five-Year Plan period, annual sales of construction machinery such as excavators and road rollers are 50,000 units, annual demand for high-strength fasteners is 2-3 million tons, and the total output value of agricultural machinery such as tractors and harvesters is 250 billion yuan. The demand for fasteners of various types of standard fasteners was over 150,000 tons, and the output value was 2 billion yuan. The laying speed of high-speed railways and passenger dedicated lines was accelerated, the investment in infrastructure reached 400 billion yuan, and the demand for fasteners was nearly 300,000 tons.

At the same time, the opportunities and challenges China is facing in becoming a world-leading economic power are also self-evident. China’s fastener products must have a place in the international market, and foreign exchanges and cooperation have become a priority. weight.

Nickel Based Alloy Powder

Nickel-based alloy powders are commonly used in plasma transfer arc welding (PTAW) due to their excellent corrosion resistance, high temperature strength, and good weldability. These alloys are typically composed of nickel as the base metal, with various alloying elements added to enhance specific properties.

Some commonly used nickel-based alloy powders for PTAW include:

1. Inconel 625: This alloy powder is widely used for PTAW due to its high strength, excellent resistance to corrosion, and oxidation at elevated temperatures. It is commonly used in applications involving seawater, chemical processing, and aerospace industries.

2. Hastelloy X: This alloy powder is known for its high-temperature strength and oxidation resistance. It is commonly used in applications involving gas turbine engines, industrial furnace components, and chemical processing.

3. Monel 400: This alloy powder is known for its excellent resistance to corrosion, particularly in marine environments. It is commonly used in applications involving seawater, chemical processing, and oil refining.

4. Inconel 718: This alloy powder is known for its high strength, excellent resistance to corrosion, and good weldability. It is commonly used in applications involving aerospace, oil and gas, and nuclear industries.

5. Inconel 601: This alloy powder is known for its excellent resistance to high-temperature oxidation and corrosion. It is commonly used in applications involving heat treatment equipment, chemical processing, and power generation.

These nickel-based alloy powders can be used in PTAW processes to create high-quality welds with excellent mechanical properties and resistance to corrosion and high temperatures.
