Isis Metals, a reputable manufacturer and supplier located in Manila, Philippines, proudly presents its top-notch Stainless Steel 420 Hollow Bars. These bars are celebrated for their remarkable strength, hardness, and resistance to corrosion. Crafted with cutting-edge technology and stringent quality controls, they’re perfect for precision machining and high-performance applications. The Stainless Steel 420 Hollow Bar from Isis Metals not only offers outstanding wear resistance and polishability but is also well-suited for various industrial and engineering tasks. With impressive dimensional accuracy and a smooth surface finish, these bars are dependable in tough environments, including mechanical, marine, and chemical sectors that demand durable, high-strength materials.
Stainless Steel 420 Hollow Bar is a martensitic stainless steel that mainly consists of chromium (12–14%), carbon (0.15–0.40%), along with trace amounts of manganese, silicon, and nickel. This unique blend strikes a great balance between strength, hardness, and moderate corrosion resistance. The alloy boasts a tensile strength ranging from 700 to 950 MPa and can be hardened through heat treatment, ensuring excellent wear resistance. It also offers good machinability and polishability, maintaining its shape under stress. Notably, SS 420 is magnetic and performs well in settings that require both mechanical strength and moderate protection against corrosion.

SS 420 hollow bars' excellent wear resistance enhances their performance by ensuring durability in high-friction environments. This property makes them ideal for cutting tools, medical instruments, and mechanical components, reducing maintenance needs and extending service life in demanding applications.
SS 420 hollow bars offer moderate high-temperature resistance but are generally not ideal for prolonged exposure to extreme heat. Their performance is best in applications requiring hardness and corrosion resistance under controlled or moderately elevated temperature conditions.
Stainless Steel 420 Hollow Bars find extensive use in industries that need components with high strength, hardness, and wear resistance. Common applications include shafts, bushings, valve parts, surgical instruments, pump components, and fasteners. They’re also popular in cutlery production, molds, and dies due to their superb polishability and ability to maintain sharp edges. In the mechanical and engineering realms, 420 Hollow Bars are trusted materials for parts that face friction and impact. Their versatility, combined with solid corrosion resistance, makes them a go-to choice for many applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
