Home > Stainless Steel 202 Nuts
Stainless Steel 202 Nuts are tough, reliable, and budget-friendly fastening components made from a special type of austenitic stainless steel that boasts impressive toughness and mechanical strength. These nuts are designed to resist corrosion in moderately harsh environments and can handle wear, pressure, and vibration with ease. SS 202 Nuts are the go-to choice when you need a solid mix of strength, affordability, and corrosion resistance. They perform consistently well in both indoor settings and light outdoor use, maintaining their structural integrity even under mechanical loads and fluctuating temperatures. Thanks to their versatility, durability, and cost-effectiveness, Stainless Steel 202 Nuts are a popular pick for a wide range of industrial and commercial applications.
These nuts are made up of about 16–18% chromium, 4–6% nickel, and 7.5–10% manganese, along with trace amounts of carbon, nitrogen, and silicon. The lower nickel content combined with higher manganese levels boosts their strength while keeping costs down. In terms of mechanics, SS 202 Nuts have a tensile strength of around 515–650 MPa and a yield strength of about 275–350 MPa. They show good toughness, formability, and work-hardening capabilities while still offering moderate corrosion resistance. These nuts excel in fresh water, mildly acidic or alkaline conditions, and environments that experience wear and mechanical stress.
