Lecong Stainless, a reputable manufacturer and supplier based in Da Nang, Vietnam, specializes in high-quality Stainless Steel 440 Bars designed for outstanding hardness, wear resistance, and strength. As part of the high-carbon martensitic stainless steel family, SS 440 is well-known for its remarkable mechanical properties that can be enhanced through heat treatment. These bars find their place in industries where durability and precision are crucial, such as aerospace, automotive, defense, and medical equipment manufacturing. Lecong Stainless guarantees that each SS 440 Bar adheres to global standards, ensuring consistent performance, reliability, and a long service life, even in the most demanding applications.
Stainless Steel 440 Bars are made with a high carbon content and contain 16–18% chromium, striking a perfect balance between hardness, toughness, and corrosion resistance. Thanks to heat treatment, they can reach hardness levels of up to 60 HRC, making them exceptionally resistant to wear, abrasion, and high stress. Mechanically, SS 440 bars offer impressive tensile and compressive strength, dimensional stability, and toughness. While their corrosion resistance may not match that of austenitic grades, their exceptional mechanical strength guarantees excellent performance in high-friction and heavy-duty situations.
