Classification
There are several different classifications of this kind of stainless steel plate, including:
UNS S31703: This is the standard specification for 317L stainless steel plate. It specifies the chemical composition, mechanical properties, and other characteristics of the material.
ASTM A240: This specification covers chromium and chromium-nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications. It includes 317L stainless steel sheet as one of the materials covered.
ASME SA240: This specification covers the requirements for chromium and chromium-nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications. It also includes 317L stainless steel plate.
EN 1.4438: This is the European standard for this kind of stainless steel plate. It specifies the chemical composition, mechanical properties, and other characteristics of the material.
Mechanical Properties
This kind of stainless steel plate is a low carbon, high molybdenum austenitic stainless steel with excellent corrosion resistance. It is often used in chemical and petrochemical industries, as well as in pulp and paper production. The following is a detailed introduction of the mechanical properties of this kind of stainless steel plate:
Tensile Strength: The tensile strength of it ranges from 515-620 MPa (75-90 ksi). This is the maximum amount of stress that the material can withstand before it breaks or deforms permanently.
Yield Strength: The yield strength of it is 205 MPa (30 ksi). This is the stress at which the material begins to deform plastically and does not return to its original shape when the stress is removed.
Elongation: The elongation of it is 40%. This is the percentage of the original length that the material can stretch before it breaks.
Hardness: The hardness of this kind of stainless steel plate is typically in the range of 150-210 HBW (Brinell hardness). This is a measure of the material's resistance to indentation or penetration.
Impact Resistance: This kind of stainless steel plate has good impact resistance at both room temperature and low temperatures. The impact toughness is typically measured using the Charpy V-notch test, and the values are typically in the range of 60-70 J (44-52 ft-lb) at room temperature.
Fatigue Resistance: This kind of stainless steel plate has good fatigue resistance, meaning it can withstand repeated cycles of stress without failure. The fatigue strength is typically measured using the S-N curve, and the values are typically in the range of 220-300 MPa (32-44 ksi).
Corrosion Resistance: It has excellent corrosion resistance in a wide range of corrosive environments, including acidic, alkaline, and chloride-containing environments.
In summary, this kind of stainless steel plate has high tensile and yield strength, good elongation, hardness, impact resistance, and fatigue resistance, making it an excellent choice for applications in corrosive environments.
Conclusion
317L stainless steel plate is a versatile and high-performance material that can be used in a wide range of applications. It has excellent corrosion resistance, high temperature resistance, formability, and strength，making it suitable for use in a variety of applications, including chemical processing, petrochemical, and oil and gas industries.The plate can be classified based on the manufacturing process, surface finish, thickness, application, and grade.If you require a material with excellent corrosion resistance and high-temperature strength, 317L stainless steel plate may be the perfect choice for your application.
