FAQ's
What is Stainless Steel 314 Seamless Pipes used for?
Stainless Steel 314 Seamless Pipes are used in high-temperature applications where excellent resistance to oxidation, scaling, and carburization is important. Common uses include furnace components (such as muffles, retorts, and heat treating baskets), heat exchangers, glass and ceramic processes, and other equipment exposed to continuous or intermittent high heat.
Which industries use Stainless Steel 314 Seamless Pipes?
The primary industries using Stainless Steel 314 Seamless Pipes are the Thermal Processing Industry (heat treatment, furnace manufacturing), Chemical Processing, Petroleum and Oil/Gas Refining, and Power Generation. Its strength and stability at elevated temperatures make it a preferred choice in these demanding sectors.
Are Stainless Steel 314 Seamless Pipes compatible with other stainless steel grades?
Yes, Stainless Steel 314 Seamless Pipes are generally compatible with other stainless steel austenitic stainless steel grades like 304 and 316 for connection and fabrication. However, when welding SS 314 to a different grade, it is important to use a filler metal that matches the specific application requirements, especially for high-temperature service, to maintain the joint’s integrity and corrosion resistance.
Can Stainless Steel 314 Seamless Pipes be used in high-temperature exhaust ducts?
Yes, Stainless Steel 314 Seamless Pipes are an excellent material for high-temperature exhaust ducts. Its high chromium and nickel content, along with high silicon, gives it superior resistance to oxidation and scaling up to 1150°C, making it ideal for exhaust systems operating under extreme heat.
What is 314 grade stainless steel?
314 grade stainless steel is a high-alloy, austenitic stainless steel. It is a modification of Type 310 stainless steel, characterized by a significantly higher silicon content along with its high chromium and nickel. This composition is specifically designed to provide excellent resistance to oxidation, scaling, and carburization at elevated temperatures, making it a “heat-resisting” grade.
What is the difference between 314 and 316 stainless steel?
The main difference lies in their application focus. SS 314 is optimized for high-temperature resistance and resistance to oxidation/scaling due to its higher chromium, nickel, and silicon content. SS 316 is optimized for corrosion resistance, especially against chlorides and acids, due to the addition of molybdenum. SS 316 generally has good high-temperature resistance but not to the same extreme degree as SS 314.
What is the equivalent of 314 stainless steel?
The most common equivalent designations for 314 stainless steel are: UNS S3140012, EN/DIN: 1.4841 and BS 314S251.
What is the melting point of 314 stainless steel?
The melting point range for 314 stainless steel is between 1400 °C – 1450 °C (2552 °F – 2642 °F).
