Harshita Stainless is a well-respected manufacturer and supplier located in Delhi, India, known for providing top-notch Stainless Steel 440B Fasteners to clients in Dubai, India, and around the globe. The company has built a reputation for delivering high-performance fastener solutions, specializing in SS 440B fasteners that boast impressive hardness, strength, and moderate resistance to corrosion. With cutting-edge machinery and rigorous quality control processes, Harshita Stainless guarantees that each product meets international standards, making them a go-to supplier for industries like aerospace, automotive, mechanical tooling, and heavy engineering that require durable and wear-resistant fastening components.
Stainless Steel 440B Fasteners are crafted from a high-carbon martensitic stainless steel alloy, containing about 16–18% chromium and 0.75–0.95% carbon. This alloy can achieve remarkable hardness and excellent wear resistance after undergoing heat treatment. In their hardened state, SS 440B fasteners can deliver tensile strength up to 740 MPa and yield strength around 450 MPa. These fasteners are magnetic, show moderate corrosion resistance in less aggressive environments, and maintain outstanding strength and dimensional stability when subjected to stress and thermal exposure.
