Nickel and society

In recent months, the government’s obvious move is to reverse the embarrassing situation in the global financial system. Commitment to invest heavily in public infrastructure to stimulate the global economy. If implemented properly, there will be long-term benefits. This investment will also benefit the nickel industry.

Nickel plays an important role in the world. Over the past decade or so, the use of nickel has increased at a rate of 3% to 4% per annum, which is mainly driven by the increasing demand for stainless steel in China. The increase in the use of nickel has benefited the world in two important ways.

First, the society benefits from the many contributions that nickel brings to the industry. These industries produce durable products, sustainably generate electricity, and build energy-efficient cars and buildings. We focus on three areas where nickel has a wide impact on society: solar energy, nuclear fusion energy, and innovative, lightweight ground transportation.

Most governments recognize the need to develop a sustainable economy. The development of a sustainable economy requires reducing greenhouse gas emissions to the atmosphere and improving energy efficiency. This trend is more evident in the EU. Nickel makes it possible to innovate in various types of active industrial activities in Europe (just three examples, fuel cells, automobiles and aerospace).

The second way to increase the demand for nickel to benefit the world is the result of derivation. Nickel-producing regions around the world benefit from the economic derivatives of nickel production. Such as the production, use and regeneration of nickel, the special reports on social and economic benefits brought to the EU, Canada and Australia. These benefits include the capital used (the total financial resources invested in the nickel industry), the economic output (the output value brought about by nickel), the added value (contribution to GDP), employment (including wages), capital expenditures, research and development, and tax.

Policymakers are often unaware of the social benefits that nickel brings to their countries and regions. These three reports use figures to illustrate how the mining, production, use, and reuse of nickel contribute to society. If one reason for the exploitation of nickel is to provide the necessary materials to take advantage of the prospects of sustainable energy production and energy efficiency, the other is the social and economic benefits of the nickel mining and processing industry itself.

Government-funded infrastructure projects may have a major impact on the nickel industry in 2009 and beyond. For example, the construction of sewage treatment plants, water treatment and conveying systems, durable concrete road bridges and buildings (using stainless steel rebar) will increase the demand for corrosion-resistant nickel-containing stainless steel. This will help stimulate the downstream industries and the nickel industry and bring long-term benefits to society.

Tapping Screw

Although there are many types of tapping screws, they all have the following similarities:
(1) are generally made of carbonized carbon steel (accounting for 99% of total production). It can also be made of stainless steel or non-ferrous metals.
(2) The product must be heat treated. Carbon steel tapping screws must be carbonized and stainless steel tapping screws must be solution hardened. In order to make tapping screws to meet the requirements of the standard of mechanical properties and performance.
(3) The product surface hardness is high, the core toughness is good. That is, "soft inside strong outside". This is a major feature of tapping Screw performance requirements. If the surface hardness is low, it can not be screwed into the matrix; If the core toughness is poor, a twist will break, can not be used. So "inside soft outside steel" is self-tapping screw to meet the use of performance, very important requirements.
(4) The surface of the product needs surface protection treatment, generally electroplating treatment. Some product surface must be treated by phosphate (photostatting), such as wall panel self - tapping screws for photostatting.
(5) Production by cold heading process. It is recommended to use high-speed cold heading machine and high-speed wire rolling machine or high-speed planetary wire rolling machine. High speed is emphasized here to ensure product quality. Only the head of tapping screw produced by high-speed machine is well formed and the thread quality is high.
