Stainless Steel 317L Flat & Spring Washers is a low-carbon version of the popular Stainless Steel 317, often referred to as "18-8" stainless steel due to its composition of 18% chromium and 8% nickel. It contains additional molybdenum which provides better corrosion resistance compared to other austenitic stainless steels. This makes Stainless Steel 317L an ideal choice for various applications, including the manufacturing of flat washers and spring washers.
Features of Stainless Steel 317L Flat Washer & Spring Washer:
Corrosion Resistance: One of the main reasons why Stainless Steel 317L is chosen for flat washer and spring washer production is its exceptional corrosion resistance. It can withstand various corrosive environments, including acidic and alkaline solutions, making it suitable for use in various industries.
Strength and durability: Stainless Steel 317L has a high tensile strength and excellent toughness, making it highly durable. This makes it an ideal choice for heavy-duty applications that require strong and long-lasting washers.
Machinability: Stainless Steel 317L has good machinability, making it easy to form into different shapes and sizes for use in various applications. It can be easily welded, bent, and stamped without any loss of corrosion resistance or strength.
Heat treatment: Stainless Steel 317L can be heat treated to increase its strength and hardness, making it suitable for use in high-temperature applications. It can withstand temperatures of up to 1700°F (927°C) without any significant loss of properties.
