Al Summan Metals, a well-regarded manufacturer and supplier based in Dubai, UAE, is recognized for its premium Stainless Steel 420 Hollow Bars. These bars are praised for their precision engineering and exceptional performance, produced to satisfy international quality standards and serve a wide range of industrial requirements. Al Summan Metals emphasizes durability, dimensional accuracy, and corrosion resistance in every item, making them a preferred option for clients across many industries. Equipped with cutting-edge manufacturing facilities, a team of experienced professionals, and a firm dedication to excellence, Al Summan Metals reliably delivers stainless steel solutions that guarantee dependability and a long service life for demanding engineering and manufacturing applications.
Stainless Steel 420 Hollow Bar is a high-carbon, martensitic stainless steel made up of roughly 12–14% chromium, 0.15% carbon, 1% manganese, together with small quantities of silicon, phosphorus, and sulfur. It offers remarkable strength, hardness, and reasonable corrosion resistance. Common mechanical properties feature a tensile strength between 700 and 850 MPa, a yield strength near 450 MPa, an elongation of 15%, and a hardness reaching up to 500 HB after heat treatment. Because the material can take a high polish and hold sharp edges, it is ideal for precision components that demand wear and corrosion resistance.

SS 317 delivers better corrosion resistance than conventional stainless steels such as SS 304 and SS 316, particularly in chloride-heavy environments. It offers improved defense against pitting, crevice corrosion, and general corrosion, which makes it well-suited for demanding chemical and marine applications.
SS 317 Hollow Bars generally consist of 18-20% chromium, 3-4% molybdenum, 13-15% nickel, along with minor quantities of manganese, silicon, and carbon. This makeup delivers outstanding resistance to corrosion, especially from chlorides, and boosts its durability at elevated temperatures.
Stainless Steel 420 Hollow Bars are widely applied across sectors that require strength, longevity, and protection against corrosion. They frequently serve in the production of shafts, pump elements, valve components, surgical tools, and cutlery. On top of this, they are used within the automotive, marine, and chemical processing fields owing to their ability to withstand severe conditions and heavy mechanical stress. Because the bars are machinable and can be heat-treated, they are well suited to tooling applications, fasteners, and mechanical parts subject to high wear. Al Summan Metals’ precisely crafted 420 hollow bars provide outstanding performance in both structural and functional roles, guaranteeing dependability in demanding engineering settings.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
