Al Summan Metals, a highly regarded manufacturer and supplier based in Dubai, UAE, focuses on premium **Stainless Steel 420 Hollow Bars**. These bars are renowned for their remarkable hardness, wear resistance, and capacity to resist corrosion. Every hollow bar is carefully produced to meet international standards, ensuring reliable performance throughout a range of industrial, mechanical, and tooling applications. Combining high carbon with moderate chromium, 420 stainless steel provides outstanding hardness, edge retention, and durability, while still delivering respectable corrosion resistance. Al Summan Metals’ 420 Hollow Bars are ideal for jobs requiring precision, strength, and longevity, making them well-suited for cutting tools, shafts, bearings, and other high-stress components within the industrial and engineering sectors.
The Stainless Steel 420 Hollow Bars are composed of roughly 12–14% chromium, 0.15–0.40% carbon, plus small quantities of manganese, silicon, and phosphorus. This distinctive makeup produces high hardness, strong wear resistance, and moderate resistance to corrosion. They deliver remarkable mechanical properties, featuring a tensile strength in the 600–800 MPa range, yield strength from 275–450 MPa, and elongation of 15–25%. Owing to their martensitic structure, these bars provide outstanding toughness, fatigue resistance, and dimensional stability, which makes them a great fit for high-stress, wear-intensive, and precision applications.

SS 420 hollow bars' outstanding wear resistance boosts their performance by guaranteeing durability in high-friction settings. This characteristic makes them perfect for cutting tools, medical instruments, and mechanical components, lowering maintenance requirements and prolonging service life in demanding applications.
SS 420 hollow bars provide moderate resistance to high temperatures but are usually not well suited for extended exposure to extreme heat. They perform best in applications that call for hardness and corrosion resistance under controlled or moderately raised temperature conditions.
Al Summan Metals’ Stainless Steel 420 Hollow Bars are used across numerous industries where hardness, wear resistance, and corrosion protection matter most. They work especially well for producing knives, cutting tools, shafts, bearings, fasteners, and surgical instruments. In addition, they serve in pump components, valve parts, and high-stress mechanical assemblies. Beyond cutting weight, the hollow construction retains strength, which makes them perfect for tooling, machinery, and precision engineering work. Their combination of hardness, corrosion resistance, and durability guarantees a long service life, dependable performance, and high efficiency in demanding industrial operations.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
