Aung Metals, a well-respected manufacturer and supplier located in Naypyidaw, Myanmar, specializes in high-quality **Stainless Steel 420 Hex Bars**. These bars are celebrated for their impressive hardness, resistance to corrosion, and overall durability. Crafted with precision to meet international standards, they promise reliable performance across various industrial, mechanical, and tooling applications. With a high carbon content and moderate levels of chromium, 420 stainless steel delivers exceptional hardness and wear resistance while still offering solid protection against corrosion. Aung Metals’ 420 Hex Bars find their place in applications that demand precision, strength, and durability, such as cutting tools, machinery components, and general engineering sectors, ensuring long-lasting performance and operational efficiency.
These Stainless Steel 420 Hex Bars contain about 12–14% chromium, 0.15–0.40% carbon, along with trace amounts of manganese, silicon, and phosphorus. This unique blend results in high hardness, good corrosion resistance, and excellent wear resistance. They boast impressive mechanical properties, including a tensile strength ranging from 600–800 MPa, yield strength between 275–450 MPa, and an elongation of 15–25%. Thanks to their martensitic structure, they offer superior toughness, hardness, and fatigue resistance, making them perfect for high-stress, wear-intensive, and precision applications across a variety of industrial settings.

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.
Aung Metals’ Stainless Steel 420 Hex Bars are extensively utilized in industries that prioritize hardness, wear resistance, and corrosion protection. They’re perfect for crafting knives, cutting tools, bearings, shafts, and surgical instruments. Additionally, these bars are employed in fasteners, pump components, valve parts, and general engineering applications that face moderate corrosive conditions. Their blend of hardness, strength, and corrosion resistance guarantees reliable performance, a long service life, and durability in demanding industrial, mechanical, and tooling operations.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
