Anucha Metals, a well-respected manufacturer and supplier based in Bangkok, Thailand, specializes in high-quality Stainless Steel 420 Hex Bars that adhere to international standards for strength and durability. These bars are celebrated for their impressive hardness, wear resistance, and ability to be polished, making them ideal for tough industrial applications. Crafted with precision and a commitment to quality, Stainless Steel 420 Hex Bars are highly sought after in various sectors, including automotive, surgical equipment, cutlery, and engineering. Anucha Metals prides itself on providing cost-effective solutions, delivering products that blend toughness, reliability, and long-lasting performance for clients both at home and abroad.
Stainless Steel 420 Hex Bar is a martensitic stainless steel that contains 12–14% chromium and 0.15–0.40% carbon, along with small amounts of manganese, silicon, and phosphorus. This unique composition allows for high hardness and wear resistance after heat treatment, while still offering moderate corrosion resistance in less harsh environments. In terms of mechanical properties, it boasts a tensile strength ranging from 700–950 MPa, a yield strength of about 340 MPa, and decent ductility. After heat treatment, 420 Hex Bars achieve remarkable hardness and dimensional stability, making them perfect for precision tools, cutting applications, and components that need to withstand wear.

The Hex Bar shape offers improved grip, stability, and easier alignment during machining or fabrication. It reduces rotation and slippage, allowing for more accurate cuts and efficient handling, especially when working with the hard, durable SS 420 stainless steel.
SS 420 Hex Bars are commonly used in applications requiring high wear resistance, such as shafts, valves, and tools. Its ability to be heat-treated for superior hardness and strength makes it ideal for demanding environments compared to other stainless steel grades.
Stainless Steel 420 Hex Bars find extensive use in creating surgical instruments, knives, scissors, and cutlery, thanks to their sharp cutting edge and ability to retain a polished finish. In the automotive and engineering sectors, they are utilized in shafts, pump parts, fasteners, and machine components that require both strength and wear resistance. They are also essential in the production of dies, molds, and tools where hardness and dimensional accuracy are vital. Furthermore, Stainless Steel 420 Hex Bars are used in hardware, construction, and general machinery, proving to be versatile materials for a wide range of industrial and commercial applications.
