Nakamura Stainless is a reputable manufacturer and supplier based in Pulau Ujong, Singapore, known for its top-notch stainless steel products tailored for demanding industrial applications. One of their standout offerings, the Stainless Steel 440C Coils, is highly regarded for its remarkable hardness, wear resistance, and mechanical strength. As a high-carbon martensitic stainless steel, 440C excels in high-stress environments while providing moderate corrosion resistance. Nakamura Stainless is committed to precision manufacturing and upholding international quality standards, ensuring that their Stainless Steel 440C Coils are durable and reliable for a variety of industrial uses.
These Stainless Steel 440C Coils are made from high-carbon martensitic stainless steel, featuring 16–18% chromium and about 1.0–1.2% carbon. This specific composition allows for heat treatment that achieves impressive hardness (up to 58 HRC) and tensile strength that surpasses 760 MPa. The alloy is known for its excellent wear resistance, fatigue strength, and toughness, making it perfect for applications that demand long-lasting mechanical performance. While its corrosion resistance is moderate compared to austenitic stainless steels, 440C Coils shine in wear-intensive and high-load environments.
