High temperature resistant stainless steel pipe, also known as 310S (0Cr25Ni20) stainless steel, is austenitic chromium nickel stainless steel, with good corrosion resistance, because of the high content of chromium nickel, it has good creep strength, can work continuously at high temperature, has good high temperature resistance.

Due to the high content of nickel (Ni) chromium (CR), it has good corrosion resistance, acid alkali resistance high temperature resistance. High temperature resistant steel pipe is especially used in the production of electric furnace tube. After the carbon content in austenitic stainless steel increases, its strength is improved due to its solution strengthening effect. The chemical composition of austenitic stainless steels is based on chromium nickel. Molybdenum, tungsten, niobium titanium are added. Because of its face centered cubic structure, it has high strength high temperature creep strength.

The specification of high temperature resistant stainless steel pipe cold drawn seamless pipe: outer diameter: 6mm-940mm; wall thickness: 0.8mm-60mm, plasma welding, argon arc welding pipe specification: outer diameter 12mm-2540mm; wall thickness 0.5mm-30mm 310S stainless steel management theoretical weight calculation formula: (outer diameter wall thickness) × wall thickness × 0.02491 = kg / m

The brittleness of carbon tool steel the extension of tool life. The quality of vacuum degassing refining steel is stable. Good hardenability, oil quenching (less quenching deformation), good toughness durable tools.

Stainless steel export is an important part of China's export economy. It plays an important role in promoting China's economic growth. However, the current situation of China's stainless steel foreign trade, China's stainless steel export encountered greater resistance.

Foreign news frequently reports the "double reversal" of 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 China's stainless steel industry, accounts for the proportion of its industrial development. In the face of huge market share economic downturn, the development of China's stainless steel industry should constantly improve product quality, develop overseas trade deal with the suppression of trade protectionism. The combination of environmental protection, energy resources human environment to enhance the competitiveness of stainless steel products is the way to maintain an invincible position in foreign trade.

In the face of external export difficulties, on the one hand, China's stainless steel industry should safeguard its own rights interests, but it is important for China's stainless steel industry to continuously improve its own quality level.
