310 Stainless Steel
310 STAINLESS STEEL
310 Stainless steel (also known as Alloy 310 or SS 310) is a highly sought after material for various applications due to its excellent resistance to oxidation, sulfidation, and hot corrosion. This attribute makes it ideal for use in moderate carburizing environments in the petrochemical industry. However, it is not recommended for severe thermal shock or repeated liquid quenching.
310 is versatile and can be used in many product forms with varying grain sizes and carbon content, making it suitable for both 310S and 310H requirements. Additionally, its ability to maintain high toughness at cryogenic temperatures and low magnetic permeability makes it a great choice for such applications.
When it comes to machining, 310 has a 42% machinability rating compared to AISI B1112 steel, equating to approximately 70 surface feet per minute when using high-speed steel tooling. It is recommended to perform forming operations at room temperature to ensure optimal results.
Welding with either AWS E310-15 electrodes or ER310 bare wire is advised to obtain the best results.

Industries and Applications
Stainless steel 310 is high-performance steel has a wide range of uses in several industries, making it a versatile and indispensable material.
One of the primary industries that extensively uses Stainless Steel 310 is the petrochemical industry. This material is ideal for use in moderate carburizing environments, making it perfect for various applications, including heat exchangers, boilers, and condensers.
The aerospace industry also extensively uses SS 310 for its toughness at high temperatures and low magnetic permeability. This makes it a great choice for components exposed to high temperatures in aircraft and aerospace systems.
The food and beverage industry is another area where Stainless Steel 310 finds extensive use. Its ability to resist corrosion and maintain hygiene makes it an excellent choice for food processing equipment and storage containers.
Stainless Steel 310 is also extensively used in the energy sector for its resistance to high temperatures and corrosive environments. This makes it ideal for applications such as offshore oil and gas rigs and power plants.
In the pharmaceutical industry, SS 310 is extensively used in the manufacture of high-pressure and high-temperature equipment, including sterilizers, autoclaves, and distillation columns. Its resistance to corrosion and ability to maintain hygiene make it an excellent choice for pharmaceutical applications.
Resistance to Corrosion
Stainless steel 310, is well known for its exceptional resistance to oxidation and corrosion. This high-performance steel is highly sought after for its durability and longevity, making it a popular choice for various applications in various industries.
One of the key features of SS 310 is its excellent resistance to oxidation under mild cyclic conditions up to 2000°F. This resistance to oxidation makes it ideal for use in moderate carburizing atmospheres, such as those encountered in the petrochemical industry.
In addition to its resistance to oxidation, SS 310 also has good resistance to sulfidation and other forms of hot corrosion. This makes it a great choice for applications in high-temperature and high-pressure environments, where resistance to corrosion is of utmost importance.
SS 310 is also highly resistant to cryogenic temperatures, with excellent toughness down to -450°F. This attribute makes it an excellent choice for applications that require low magnetic permeability and toughness at low temperatures.
Fabrication and Heat Treatment
Stainless Steel 310, is a highly sought after material for its exceptional resistance to oxidation and corrosion. Along with its resistance properties, the material is also known for its ease of fabrication and heat treatment.
SS 310 has a machinability rating of 42% compared to AISI B1112 steel, making it relatively easy to fabricate. With high-speed steel tooling, SS 310 can be machined at about 70 surface feet per minute. It is recommended to perform forming operations at room temperature whenever possible to prevent any adverse effects on the material’s properties.
Welding is an important fabrication process for SS 310, and it is recommended to use AWS E310-15 electrodes or ER310 bare wire for welding. This will ensure that the final product retains its resistance properties, strength, and durability.
Heat treatment is an important aspect of the fabrication process for SS 310. The material is typically used in moderate carburizing atmospheres and is not recommended for severe thermal shock caused by repeated liquid quenching. However, SS 310 can be used in high-temperature applications, and its resistance to cryogenic temperatures makes it ideal for use in low-temperature applications.
