Harshita Stainless is a reputable manufacturer and supplier located in Delhi, India, known for providing top-notch Stainless Steel 440C Nuts to clients in Dubai, India, and around the world. With a solid reputation for precision and durability, this company produces SS 440C nuts that are perfect for high-stress environments where wear and tear are common. Using advanced manufacturing techniques and strict quality controls, these nuts offer outstanding strength, hardness, and dimensional accuracy. Harshita Stainless caters to a variety of industries, including aerospace, automotive, tool manufacturing, and mechanical engineering, delivering fastening solutions that meet international standards and performance expectations.
Stainless Steel 440C Nuts are crafted from a high-carbon martensitic stainless steel alloy that contains 16–18% chromium and up to 1.2% carbon. This unique composition allows the nuts to achieve impressive hardness and excellent wear resistance after undergoing heat treatment. SS 440C boasts a tensile strength of about 760 MPa and a yield strength of around 450 MPa, with the ability to reach hardness levels of up to 60 HRC. These nuts are magnetic, heat-treatable, and provide moderate corrosion resistance, making them well-suited for dry or mildly corrosive environments where structural integrity is crucial under mechanical loads.
