Stainless Steel 420 Flat Bars are martensitic stainless steel alloys that contain 12–14% chromium and 0.15–0.40% carbon. This specific composition allows the alloy to be hardened through heat treatment, achieving high tensile strength (up to 750 MPa) and remarkable wear resistance. SS 420 also provides moderate corrosion resistance, which can be improved with surface treatments or polishing. It retains good mechanical properties and edge retention, and it can be tempered to achieve various hardness levels based on the intended application.

Stainless Steel 420 Flat Bar is commonly used in applications requiring high strength, wear resistance, and moderate corrosion resistance. It is often found in the manufacturing of surgical instruments, valves, knives, bearings, shafts, and other precision machinery components.
Stainless Steel 420 typically has a hardness range of 50-55 HRC (Rockwell Hardness). When heat-treated, it can achieve higher hardness levels, making it suitable for applications requiring wear resistance, such as cutlery, tools, and industrial components.
Yes, Stainless Steel 420 Flat Bar can be heat treated to improve strength. Through processes like annealing, hardening, and tempering, its hardness, wear resistance, and overall strength can be enhanced, making it ideal for demanding applications like cutting tools.
These Stainless Steel 420 Flat Bars are commonly utilized in scenarios where hardness, strength, and wear resistance are crucial. Typical applications include knife blades, surgical instruments, shafts, gears, cutlery, industrial tooling, and mechanical parts. In the automotive and aerospace industries, SS 420 is appreciated for its machinability and performance under stress. Its flat shape makes it ideal for brackets, base plates, and structural reinforcements. Additionally, SS 420 is employed in pump shafts and valves, where it can endure moderate corrosive environments while maintaining dimensional stability under load and abrasion.
