These bolts are built to endure moderate corrosion, wear, and stress, making them a dependable choice for engineering, mechanical, and industrial applications.
Stainless Steel 416 Bolts consist of 12–14% chromium, at least 0.15% carbon, and 0.15–0.35% sulfur to boost machinability. The alloy also contains trace amounts of manganese, silicon, phosphorus, and sulfur. As a martensitic stainless steel grade, SS 416 boasts remarkable machining properties, solid mechanical strength, and moderate resistance to corrosion. After undergoing heat treatment, these bolts achieve impressive tensile strength, excellent wear resistance, and hardness levels reaching 35–40 HRC. This makes SS 416 bolts perfect for applications that require durability and precision under mechanical stress.
