Creep strength of high temperature stainless steel

AUTHOR: admin       TIME:2021-12-29       READER:

High temperature resistant 2205 stainless steel seamless pipe has much better creep strength because of the higher percentage of chromium and nickel, can continue to operate at high temperature, and has good high temperature resistance. Due to the high content of nickel (Ni, chromium (Cr), it has good oxidation resistance, corrosion resistance, acid and alkali resistance, and high temperature resistance. Due to its solid solution strengthening effect, the strength is improved. The chemical composition characteristics of austenitic stainless steel are based on chromium and nickel, and elements such as molybdenum, tungsten, niobium and titanium are added. It has high strength and creep strength. High temperature resistant 2205 stainless steel seamless pipe is suitable for making various furnace components, with a maximum working temperature of 1300 ° C and a continuous use temperature of 1150 ° C. Its service life is 5 times that of traditional centrifugal casting pipes, The price is 1/3 of the same kind of imported products and 2/3 of the domestic specification. High temperature resistant 2205 stainless steel seamless pipe finish rolling, cold drawn seamless pipe specification: outer diameter 6mm---940mm wall thickness 0.8mm---60mm plasma welding , Pressure arc welded pipe specifications: outer diameter 12mm---2540mm wall thickness 0.5mm---30mm 2205 stainless steel management theoretical weight calculation formula: outer diameter - wall thickness) wall thickness × 0.02491 = KG/M. Purpose: high temperature resistant 2205 stainless steel without The slotted tube is suitable for making various furnace components, with a maximum working temperature of 1300 ° C and a continuous use temperature of 1150 ° C. Its service life is 5 times that of traditional centrifugal casting tubes, and the price is 1/3 of the same imported products and 2/3 of domestic resistance. High temperature 2205 stainless steel seamless pipe produces 10,000 tons of high-quality stainless steel welded pipes and 8,000 tons of seamless pipes per year. The products are widely used in petroleum, chemical, pharmaceutical, paper, shipbuilding, food, nuclear power, military, machinery, environmental protection, manufacturing Car and other industries; role: to improve the fragile nature of carbon tool steel, and to extend the life of the tool. Vacuum degassing refining steel, stable quality. Good hardenability, oil-cooling hardening (quenching crack and less deformation) ) Good toughness and wear resistance, durable tools. Materials are: 304, 304L, 316L, 304H, 347H, 304L, N321H316Ti, 316H, 317, 317L, 321, 310S, S31803, 904L and ferrite (409/409L410430436 /436L439/439L/444 and other commonly used steel grades and some special steel grades. Executive standard for high temperature resistant stainless steel seamless pipes: GB13296-2000GB/T14976-2002GB/T14975-2002ASTM/A SMEA213/A 312/A 269/A 789 /A 790EN10216-5DIN17458, etc. Welded pipe executive standard: GB/T12770-2000GB/T12771-2000ASTM/A SMEA249/A 312/A 554/A 778/A 789EN10217-7DIN17457, etc. Chemical composition: high temperature resistant 2205 stainless steel seamless pipe chemical Composition (%Ni Nickel 19.00-22.00Cr Chromium: 24.00-26.00Si Silicon <= 1.50Mn Manganese <= 2.00C Carbon <= 0.08S Sulfur <= 0.030P Phosphorus <= 0.035 Density: 8.0 g/cm3, Mechanical properties after solution treatment: Yield strength≥ 205 Tensile strength ≥ 520 Elongation ≥ 40 Hardness test: HBS ≤ 187.
