Limited resistance to some corrosive environments:
SS 304 may not perform well in highly corrosive environments containing chlorides or sulfuric acid.
SS 310:
Higher price:
SS 310 is generally more expensive than SS 304 and other stainless steels due to its higher nickel and chromium content.
Limited formatting capabilities:
It is less formable than SS 304, making it more difficult to fabricate complex shapes. Conclusion:
SS 304 and SS 310 are two valuable stainless steels with distinct uses, advantages and disadvantages. SS 304 is suitable for general purpose applications with good corrosion resistance, while SS 310 offers outstanding corrosion and heat resistance making it ideal for high temperature applications. The choice between these grades depends on specific application requirements, including temperature, corrosion resistance, and cost considerations.
Stainless steel is a widely used material in various industries due to its excellent corrosion resistance, durability and aesthetic appeal. Two commonly used stainless steel grades are SS 304 and SS 310. Although both belong to the austenitic family, they have distinct differences in composition, properties and applications. In this answer, I will explain in detail the difference between SS 304 and SS 310, including their composition, mechanical properties, corrosion resistance, heat resistance and application.
Ingredient:
SS 304:
304 stainless steel contains about 18% chromium and 8% nickel, along with small amounts of manganese, silicon, and carbon. It also includes traces of other elements such as sulfur, phosphorus and nitrogen.
SS 310:
Type 310 contains about 25% chromium and 20% nickel, along with small amounts of manganese, silicon, and carbon. It also includes traces of other elements such as sulfur, phosphorus and nitrogen.
Mechanical properties:
SS 304:
SS 304 has excellent mechanical properties including high tensile strength, good formability and high ductility. It has a tensile strength of 515 MPa (75,000 psi) and a yield strength of 205 MPa (30,000 psi). SS 310:
SS 310 has a higher mechanical strength than SS 304. It has a tensile strength of 620 MPa (90,000 psi) and a yield strength of 310 MPa (45,000 psi).
Anticorrosion:
SS 304:
SS 304 is known for its excellent resistance to corrosion in many environments. It provides good atmospheric corrosion resistance and is resistant to many corrosive media including acids, alkaline solutions and salt water. However, it is not suitable for strongly corrosive environments such as those containing chloride or sulfuric acid. SS310:
SS 310 offers superior corrosion resistance compared to SS 304, especially in high temperature environments. It has excellent oxidation resistance and can resist high temperature sulfurization and carbonization. SS 310 is highly resistant to corrosion in a variety of environments and is suitable for applications involving corrosive chemicals and acids.
Heat resistance:
SS 304:
SS 304 has good heat resistance and can withstand temperatures up to 870°C (1600°F) in continuous service and 925°C (1700°F) in intermittent service.
SS310:
SS 310 has exceptional heat resistance and can withstand higher temperatures than SS 304. It can operate at temperatures up to 1150°C (2100°F) in continuous operation and 1035°C (1900°F) in intermittent operation. This makes SS 310 suitable for high temperature applications such as ovens, furnaces and heat treatment equipment.
Applications:
SS 304:
SS 304 is widely used in many applications including food processing equipment, kitchen equipment, architectural structures and chemical handling equipment. It is suitable for general purpose applications that require good corrosion resistance and formability, but is not resistant to high temperatures.
SS310:
SS 310 is specially designed for high temperature applications. It is used in furnace components, heat exchangers, refractory anchors, heat treatment equipment and chemical processing equipment. SS 310 is chosen where corrosion resistance and high temperature resistance are required.
Conclusion
SS 304 and SS 310 are two common austenitic stainless steel grades but differ in composition, mechanical properties, corrosion resistance, heat resistance and application. SS 304 is suitable for general purpose applications with good corrosion resistance.
