Tariku Metals, a reputable manufacturer and supplier located in Addis Ababa, Ethiopia, focuses on providing top-notch Stainless Steel 420 Hollow Bars that boast remarkable hardness, strength, and resistance to corrosion. These hollow bars are crafted with meticulous quality control to align with international standards and meet the rigorous demands of various industries. Renowned for their superb machinability and polishability, SS 420 Hollow Bars are perfect for applications that require high wear resistance and moderate protection against corrosion. Tariku Metals guarantees precision engineering, dimensional accuracy, and a flawless surface finish, making their Stainless Steel 420 products a reliable choice for machinery, tooling, and mechanical industries around the globe.
Stainless Steel 420 Hollow Bars are martensitic stainless steels made up of roughly 12–14% chromium, 0.15% carbon, along with trace amounts of manganese, silicon, and phosphorus. This specific blend enables the alloy to achieve impressive hardness and strength after undergoing heat treatment. The bars display a tensile strength ranging from 700–950 MPa, a yield strength of about 450 MPa, and can reach hardness levels of up to 500 HB when hardened. SS 420 offers decent corrosion resistance in mild environments, outstanding wear resistance, and maintains its mechanical stability even at elevated temperatures, making it an excellent choice for shafts, bushings, and high-stress machine components.

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 applications that demand exceptional strength, toughness, and wear resistance. They are perfect for crafting pump shafts, valve stems, surgical instruments, nozzles, and machine parts that face frictional forces. In the tooling and engineering fields, they are utilized for producing spindles, bolts, dies, and measuring instruments, thanks to their ability to achieve a finely polished finish. SS 420 Hollow Bars are also employed in the petrochemical, automotive, and food processing industries, where components require durability and reliability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
