They cater to a range of industries, including marine, petrochemical, automotive, and construction, with a focus on delivering robust and efficient fastening components designed to meet diverse industrial demands.
**Stainless Steel 440C Nuts** are made from high carbon martensitic stainless steel, featuring a blend of chromium (16–18%), carbon (0.95–1.20%), manganese, molybdenum, and silicon. This unique composition results in outstanding hardness, tensile strength, and corrosion resistance. These nuts boast a tensile strength between 760–1000 MPa and a yield strength of up to 450 MPa, along with impressive wear and fatigue resistance. The 440C alloy can be heat-treated to enhance its mechanical performance, providing superior strength and dimensional stability, particularly in applications that face high stress, friction, or corrosive conditions.
