Introduction

The Ss 410 stainless steel round bar is a high-quality stainless steel material that is widely used in machinery manufacturing, the automobile industry, architectural decoration, and tool manufacturing. It belongs to the martensitic stainless steel series, containing about 11.5% to 13.5% chromium, as well as a certain amount of carbon, silicon, manganese, and other elements, giving it unique physical and chemical properties. In machinery manufacturing, it is often used to manufacture high-stress parts such as knives and molds; in the automotive industry, it can be used to manufacture key parts such as engine parts and transmission systems; in the field of architectural decoration, it is often used to make decorative components such as railings and handrails.

Features

High strength and hardness

Thanks to the phase transformation of its martensitic structure during heat treatment, the grains inside the material are refined, thereby enhancing its mechanical properties. After quenching and tempering, the tensile strength of Ss 410 2mm 3mm 6mm Stainless Steel Round Bar can reach about 750MPa, and the hardness value can reach HB220-280.

Good magnetic properties

Unlike non-magnetic austenitic stainless steel, Ss 410 2mm 3mm 6mm Stainless Steel Round Bar is magnetic due to its martensitic structure. Ss 410 2mm 3mm 6mm Stainless Steel Round Bar contains ferromagnetic elements such as iron, nickel, and chromium, and has a moderate magnetic permeability, usually between 700 and 1000, which can meet the needs of electromagnetic induction, magnetic recording, and other electronic equipment for magnetic materials.

Corrosion resistance

The chromium element in Ss 410 2mm 3mm 6mm Stainless Steel Round Bar can form a dense oxide film on the material's surface, preventing the corrosive medium from directly contacting the metal matrix inside the material, thereby slowing down the corrosion rate. In 3% sodium chloride solution, after 240 hours, the corrosion rate of Ss 410 2mm 3mm 6mm Stainless Steel Round Bar is only 0.01mm/year, which is much lower than the corrosion rate of ordinary carbon steel (usually 0.1-0.5mm/year).
