Economic performance of 304 stainless steel pipe
Stainless steel export is an important part of China's export economy and plays an important role in stimulating China's economic growth. However, judging from the foreign trade of stainless steel in China, the export of stainless steel in China met with great resistance.
Since last year, foreign countries have frequently reported "double opposition" to China's stainless steel casting products, which has a great impact on China's stainless steel casting industry. Export is an important part of the development of stainless steel industry in China and occupies a huge market share in the development of stainless steel industry in China. Facing the economic downturn and slow development, the development of stainless steel industry in China should constantly improve the product quality. Only by better developing overseas trade, coping with the suppression of trade protectionism, combining products with environmental protection, energy resources and human environment, and enhancing the competitiveness of stainless steel products, can we be invincible in foreign trade.
In view of external export difficulties, China stainless steel industry should protect its rights on the one hand, but the most important thing is that China stainless steel industry should constantly improve its own quality level and upgrade in an all-round way.
Difference and connection
304 stainless steel pipe is a stainless steel brand produced according to American ASTM standard. 304 stainless steel pipe is equivalent to China's 0Cr 19Ni9? (0Cr 18Ni9) stainless steel pipe. 304 contains 19% chromium and 9% nickel.
304 stainless steel pipe is widely used as stainless and heat-resistant steel, which is used in food equipment, general chemical equipment and atomic energy industry equipment.
304? Stainless steel pipe is a general stainless steel pipe, which is widely used to manufacture equipment and parts that require good comprehensive performance (corrosion resistance and formability).
304 stainless steel pipe is the most widely used stainless steel and heat-resistant steel. Used in food production equipment, chemical equipment, nuclear energy, etc.
Chemical composition of 304 stainless steel pipe? Specifications? c？ Is it? Mn？ p？ s？ Cr？ Ni (nickel)? molybdenum
SUS304？ ≤0.08? ≤ 1.00? ≤2.00? ≤0.05? ≤0.03? 18.00-20.00? 8.25~ 10.50
From the metallographic point of view, because stainless steel contains chromium, a thin chromium film is formed on the surface, which isolates the oxygen invading the steel and plays a role in corrosion resistance. In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 12% chromium.
The above is the 304 steel pipe manufacturer introduced by Bian Xiao. 304 steel pipe is a kind of general stainless steel pipe, which has excellent performance and wide application.
