Features: because adding Mo, so the corrosion resistance, resistance to atmospheric corrosion and high temperature strength are particularly good, can be used in the harshness of the conditions; hardening excellent (non-magnetic); excellent high temperature strength; non-magnetic solid solution; cold rolled product appearance, good gloss, beautiful; 304 relatively higher prices. 316 stainless steel by adding Mo elements to corrosion resistance, and high temperature strength has greatly improved, high temperature can reach 1200-1300 degrees, can be used in the harshness of the conditions. Uses: sea water equipment, chemicals, dyes, paper, oxalic acid, fertilizer and other production equipment; photography, food industry, coastal facilities, ropes, CD rods, bolts and nuts.

Uses: sea water equipment, chemicals, dyes, paper, oxalic acid, fertilizer and other production equipment; photography, food industry, coastal facilities, ropes, CD rods, bolts and nuts. 410 Features: As a representative of martensitic steel steel, although high intensity, but not for the harshness of corrosive environments; its processing is good, according to surface hardening heat treatment (magnetic). Uses: blade, machine parts, petroleum refining unit, bolts, nuts, pump rod, a class of cutlery (fork). 3 difference is now the most commonly used two stainless steel 304, 316 (or corresponding to the German / European standard 1.4308,1.4408), 316 and 304 main difference in the chemical composition is the 316 Mo, and is generally accepted that the corrosion resistance of 316 better than 304 in a high temperature environment more resistant to corrosion. Therefore, in high temperature environment, engineers usually use component 316 material. But no matter the so-called absolute, in concentrated sulfuric acid environment, then do not use high temperature 316! Otherwise, this thing may out big. Studied mechanical engineering who have learned thread, I still remember in order to prevent thread killed at high temperatures, you need to apply a dark solid lubricant bar: molybdenum disulfide (MoS2), obtained from it 2:00 conclusion is not: [1] Mo is indeed a high temperature material (to know what the gold crucible melting it molybdenum crucible?!). [2]: molybdenum sulfide is easy and high reaction sulfide. So there is no any kind of stainless steel is corrosion-resistant super-invincible. After all, stainless steel is an impurity (However, these impurities can be more corrosion resistant than steel ^ ^) more steel, steel and other materials can react. 4 stainless steel export-related information is an important part of China's export economy, its driving China's economic growth has an important role, however, from the current situation of China's foreign trade of stainless steel, the country's steel exports encounter greater resistance. Since last year, overseas frequently came to China's stainless steel casting products for "dual" message, which has a great impact on China's stainless steel casting industry in terms of industrial development of China's steel exports are a large part in its industry development occupies a huge market share in the face of the current economic downturn, the slowdown of the situation, the development of China's steel industry should continue to improve product quality, the better development of foreign trade and respond to pressure from trade protectionism , product and environmental protection, energy resources, human environment combine to enhance the competitiveness of stainless steel products, the only way to achieve the status of unbeaten in foreign trade. For, external export difficulties, China's steel industry on the one hand you want to safeguard their rights, but the most important thing of the stainless steel industry to continuously improve their level of quality, and a comprehensive upgrade of 316F stainless steel is easy to cut sulfur content higher. Good corrosion resistance, easy to drive and easy processing, good finish, apply to the axis and other parts. Chemical composition (%): SUS316F stainless added Mo, corrosion resistance, resistance to atmospheric corrosion and high temperature strength are particularly good, can be used in the harshness of the conditions; hardening excellent (non-magnetic).

Many people think that stainless steel is never rust, in fact, good corrosion resistance of stainless steel. The reason is that the surface layer of the passivation film, it is a more stable form of oxides exist in nature. That is, although the stainless steel according to the different conditions of use, the degree of oxidation is not the same, but in the end is oxidized, a phenomenon often called etching. Exposed to the corrosive environment of the metal surface occurs all electrochemical reactions or chemical reactions, uniform corrosion. 316 stainless steel surface passivation film corrosion resistance among the weak parts, due to the self-excited reaction to form pitting reaction of holes, coupled with chloride ions close to form highly corrosive solution, to accelerate the corrosion reaction speed. There are between internal corrosion cracking of stainless steel, all of which the passive film on the surface of the stainless steel plate damaging effects occur. Therefore, the stainless steel surface cleaning and maintenance must be carried out on a regular basis to maintain its gorgeous surface and prolong life.
