Chinese steel industry has developed rapidly during the past 10 years, it has become the world's largest amount of steel, manufacturing construction strongest, the first industrial scale, enterprise-scale steel big country first. Steel Enterprise: Must be "second five" development around the successful construction of major steel works, steel structure shows that our integrated technology has been in the international advanced level. However, China's steel industry in information technology, automation, standardization, innovation, research, compared with developed countries, there is not a small gap. 2011 is the national "five" plan Begins, the relevant state ministries, industry associations and business groups, steel companies are conducting research, market analysis and future trends. National Development and Reform Commission, Ministry of Industry, Science and Technology is also a strategic new industry research on the identification and planning goals of the international advanced level, independent innovation ability, strong international competitiveness and can occupy more market industry, will be included in the planning and administration support policies. Opportunities and challenges, China's steel industry can on the steps on the scale, critical to the development "five" period. Many factors influence the durability of steel durability. The first is the difference in corrosion-resistant steel, must take protective measures to prevent steel corrosion rust. Protective measures include: regular maintenance of steel paint, galvanized steel, in the presence of acid, Hefei steel manufacturers, alkali, salt and other corrosive medium conditions, the use of special protective measures, such as offshore platform structure using an "anode protection" measures to prevent Jacket corrosion, Hefei steel, pipe rack fixed in the ingot, Hefei steel construction, water will automatically be corrosive electrolyte zinc, thereby protecting the steel jacket features. Second, because of the steel at high temperatures and long loads, its breaking strength than the short-term strength decreases more, so long steel under high temperature, long term strength to be determined. Steel will automatically harden over time, become brittle, or "aging" phenomenon. Steel under low temperature loads to test its toughness.
