254SMO stainless steel rod introduction
254SMO is a high alloy austenitic stainless steel with excellent corrosion resistance, especially in chloride environments. Its high molybdenum content (6%) and nitrogen content (0.18%) make it excellent in resistance to pitting corrosion, crevade corrosion and stress corrosion cracking. 254SMO is widely used in harsh environments such as offshore engineering, chemicals, oil and gas.
Chemical composition
The typical chemical composition of 254SMO stainless steel is as follows (% by weight) :
- Element content (%)
- Carbon (C) ≤ 0.02
- Chromium (Cr) 19.5-20.5
- Nickel (Ni) 17.5-18.5
- Molybdenum (Mo) 6.0-6.5
- Nitrogen (N) 0.18-0.22
- Manganese (Mn) ≤ 1.0
- Silicon (Si) ≤ 0.8
- Phosphorus (P) ≤ 0.03
- Sulfur (S) ≤ 0.01
- Copper (Cu) 0.5-1.0
Mechanical property
Typical mechanical properties of 254SMO stainless steel are as follows:
- Performance index value
- Tensile strength (MPa) 650-850
- Yield strength (MPa) 300-400
- Elongation (%) ≥ 35
- Hardness (HB) ≤ 220
- specification
Common specifications for 254SMO stainless steel rods include:
- Diameter range: usually 5mm to 300mm, the specific specifications can be customized according to demand.
- Length: Generally 3 meters or 6 meters, can also be customized according to customer requirements.
- Surface treatment: black leather, car, polishing, etc.
peculiarity
- Excellent corrosion resistance: Excellent resistance to pitting, crevice corrosion and stress corrosion cracking in chloride environments.
- High strength: High alloy composition gives it high mechanical strength.
- Good welding performance: suitable for various welding methods, still maintain good corrosion resistance after welding.
- High temperature performance: maintain good mechanical properties and corrosion resistance at high temperatures.
- Wide application: Suitable for a variety of industrial applications in harsh environments.
Common brand
The grades of 254SMO in different standards correspond to the following:
Standard grade
- UNS S31254
- EN 1.4547
- ASTM A240
- DIN X1CrNiMoCuN20-18-7
Standard
254SMO stainless steel rods are manufactured and tested according to the following standards:
- ASTM A276: Standard for Stainless Steel bars and profiles.
- ASTM A479: Standard for Stainless Steel Bars and Profiles for Boilers and other pressure vessels.
- EN 10088-3: European Standard for stainless steel bars, wires and profiles.
- GB/T 1220: China national standard, suitable for stainless steel bars.
Application field
254SMO stainless steel rods are widely used in the following areas:
- Marine engineering: Used in seawater desalination equipment, seawater cooling systems, offshore platforms, etc.
