These coils are renowned for their remarkable hardness, strength, and resistance to wear. Crafted with precision, they meet the rigorous demands of industries that require top-notch performance even in tough conditions. The Stainless Steel 440C Coils are highly regarded for their ability to endure high stress, resist abrasion, and handle moderate corrosion. With state-of-the-art production facilities and stringent quality control measures, Lecong Stainless ensures that their coils are reliable and durable, adhering to global standards. This makes them a fantastic choice for various industrial, engineering, and manufacturing applications both in Vietnam and around the globe.
The composition of Stainless Steel 440C Coils includes a high carbon content along with chromium (16–18%), manganese, silicon, and trace elements, resulting in a martensitic microstructure. This unique blend gives them exceptional hardness, tensile strength, and wear resistance. They boast a tensile strength of about 760 MPa, a yield strength of 450 MPa, and impressive hardness levels reaching up to 58 HRC when heat-treated. Although their corrosion resistance is moderate compared to austenitic grades, Stainless Steel 440C Coils excel in environments where strength and abrasion resistance are crucial. Their ability to maintain toughness at high hardness levels makes them ideal for demanding mechanical applications.
