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
UNSS31254
EN 1.4547
ASTMA240
DINX1CrNiMoCuN20-18-7
