Sahil Metals stands out as a top manufacturer and supplier in Riyadh, Saudi Arabia, focusing on high-quality Stainless Steel 420 Hollow Bars that are designed for strength, durability, and precision. SS 420 is a martensitic stainless steel grade celebrated for its impressive hardness, wear resistance, and decent corrosion resistance. At Sahil Metals, we produce 420 Hollow Bars with a commitment to international standards, ensuring they are dimensionally accurate, have a smooth finish, and boast a long service life. These bars are essential in various industries, including automotive, medical, oil & gas, tool-making, and engineering, where reliability, machinability, and durability are key.
Stainless Steel 420 Hollow Bars generally consist of 12–14% chromium and 0.15–0.40% carbon, along with trace amounts of manganese, silicon, phosphorus, and sulfur. This specific blend allows for impressive hardness levels of 48–52 HRC after heat treatment, making SS 420 exceptionally wear-resistant. It provides a tensile strength of 650–850 MPa and a yield strength of about 500 MPa. Additionally, SS 420 showcases moderate corrosion resistance, good machinability, and excellent polishability, making it ideal for precision tools. Its martensitic structure guarantees toughness and durability, especially under thermal or mechanical stress.
