Hardness testing to ISO 6508-1
Stainless steel 317L hex bolts are high strength fasteners used in a variety of applications due to their exceptional corrosion resistance and durability. In this guide, we will discuss the features, machining, heat treatment, applications, and corrosion resistance of stainless steel 317L hex bolts.
Features of Stainless Steel 317L Hex Bolts Stainless steel 317L hex bolts are made from a low carbon version of stainless steel 317, which contains higher levels of chromium, nickel, and molybdenum. This results in increased resistance to corrosion, making them suitable for use in harsh environmental conditions or applications that require exposure to high temperatures.
The addition of molybdenum also improves the strength and workability of stainless steel 317L hex bolts, making them ideal for heavy-duty applications.
Machining Stainless Steel 317L Hex Bolts Stainless steel 317L hex bolts are easy to machine, thanks to their low carbon content and ductility. However, due to their high strength, specialized tools and techniques may be required for efficient machining. It is important to use proper lubrication during the machining process to prevent overheating and maintain the corrosion resistance of the bolts.
Heat Treatment of Stainless Steel 317L Hex Bolts Stainless steel 317L hex bolts can be heat treated to further enhance their strength and hardness. This process involves heating the bolts to a specific temperature and then cooling them at a controlled rate. The result is increased durability and resistance to wear and tear, making stainless steel 317L hex bolts suitable for demanding applications.
Applications of Stainless Steel 317L Hex Bolts Stainless steel 317L hex bolts are commonly used in industries such as chemical processing, oil and gas, food and beverage, and marine due to their exceptional corrosion resistance. They are also used in construction, automotive, and aerospace industries for their strength and durability.
Other applications of stainless steel 317L hex bolts include fastening equipment in high temperature environments, such as boilers and heat exchangers. They are also used in pulp and paper processing, pharmaceuticals, and nuclear power plants.
