Al Summan Metals, a highly regarded manufacturer and supplier based in Dubai, UAE, focuses on premium **Stainless Steel 420 Rectangular Bars**. These bars are renowned for their remarkable hardness, resistance to wear, and capacity to resist corrosion. Every rectangular bar is carefully produced to comply with international standards, ensuring reliable performance across diverse industrial, mechanical, and tooling applications. Through a combination of high carbon and moderate chromium, 420 stainless steel provides outstanding hardness, edge retention, and durability, while still delivering decent corrosion resistance. Al Summan Metals’ 420 Rectangular Bars are ideal for jobs requiring strength, precision, and longevity, making them well-suited for cutting tools, machinery components, and high-stress industrial applications throughout a variety of engineering fields.
These 420 Stainless Steel Rectangular Bars are made up of roughly 12–14% chromium, 0.15–0.40% carbon, plus small quantities of manganese, silicon, and phosphorus. This distinctive makeup delivers high hardness, strong wear resistance, and moderate corrosion resistance. They feature notable mechanical properties, such as a tensile strength of 600–800 MPa, yield strength of 275–450 MPa, and elongation of 15–25%. Owing to their martensitic microstructure, these bars provide outstanding toughness, fatigue resistance, and dimensional stability, which makes them a great fit for high-stress, wear-intensive, and precision uses in industrial settings.
