Poang Fasteners is a well-respected manufacturer and supplier of Stainless Steel 440C Washers based in Da Nang, Vietnam. We provide high-strength fastening solutions that are specifically designed for tough industrial environments. Stainless Steel 440C is a high-carbon martensitic stainless steel recognized for its remarkable hardness, wear resistance, and decent corrosion resistance. Our SS 440C Washers are crafted to evenly distribute loads, prevent surface damage, and improve joint stability in heavy-duty applications. Manufactured according to ASTM, DIN, and ISO standards, these washers find extensive use in aerospace, defense, petrochemical, marine, and automotive industries where durability, precision, and resistance to mechanical stress are essential.
Stainless Steel 440C Washers consist of 16–18% chromium, 0.95–1.20% carbon, 0.75% molybdenum, along with trace amounts of manganese and silicon. This alloy provides outstanding hardness (up to 58 HRC when heat-treated), excellent wear resistance, and good dimensional stability. With tensile strength ranging from 760–1100 MPa and a yield strength of around 450–600 MPa, SS 440C stands up well under mechanical stress. While its corrosion resistance is moderate compared to austenitic grades, it effectively endures mildly corrosive and high-stress environments. These characteristics make 440C Washers perfect for applications that demand extreme hardness, toughness, and reliable fastening performance.
