Stainless Steel 321 Screw

The composition of 321 stainless steel screws is outlined below. It contains a minimum of 17% chromium, 9%-12% nickel, 0.75% silicon, 0.08% carbon, 2% manganese, 0.045% phosphorus, 0.03% sulfur, and a maximum of 0.75% copper. This type of stainless steel is commonly used in high-temperature applications due to its effective heat resistance properties.

321 SS Screws are a type of austenitic stainless steel screws. They have excellent corrosion resistance and strength in high temperatures and offer good formability. These screws are commonly used in applications where they will be exposed to high temperatures, such as exhaust systems and pressure vessels. They also offer good weldability, toughness, and ductility, making them suitable for various uses. Additionally, these screws are often used in the food industry due to their resistance to chloride ion corrosion.
