They cater to various industries, including petrochemical, automotive, marine, and engineering, providing reliable 440-grade stainless steel bars that promise long-lasting performance, even in the toughest and most demanding environments across Congo and beyond.
**Stainless Steel 440 Bars** are made from high-carbon martensitic stainless steel, which contains chromium (16–18%), carbon (0.95–1.20%), along with trace amounts of molybdenum, manganese, and silicon. This unique blend gives the bars their exceptional hardness, wear resistance, and moderate corrosion protection. They showcase a tensile strength ranging from 760–1000 MPa and a yield strength of about 450 MPa. With high dimensional stability, these bars can also be heat-treated to boost their hardness. These mechanical properties make 440 stainless steel bars perfect for applications that require both strength and resistance to wear and fatigue.
