Their Stainless Steel 317 Flat Bars are engineered to deliver exceptional corrosion resistance, strength, and durability, guaranteeing reliable performance even in demanding conditions. With a firm emphasis on excellent manufacturing methods, dependable quality, and on-time delivery, Al Summan Metals has established itself as a trusted supplier, offering stainless steel solutions that combine efficiency, longevity, and value for industries across UAE and beyond.
Stainless Steel 317 Flat Bars belong to the austenitic stainless steel family and offer improved corrosion resistance owing to their elevated molybdenum content. Their composition generally features 18–20% chromium, 11–13% nickel, and 3–4% molybdenum, granting them outstanding resistance to pitting, crevice corrosion, and severe chemical conditions. From a mechanical standpoint, these flat bars deliver a tensile strength between 515 and 690 MPa, a yield strength of 205 to 275 MPa, and an elongation of roughly 40%, offering exceptional toughness, ductility, and formability. Because they remain stable at elevated temperatures and resist oxidation, they are ideal for demanding applications in aggressive industrial environments.

Stainless Steel 317 consists mainly of iron, chromium (roughly 18-20%), nickel (11-15%), and molybdenum (3-4%). It also includes minor quantities of manganese, silicon, and carbon, providing outstanding corrosion resistance, particularly in acidic conditions.
Yes,Stainless Steel 317 Flat Bar offers strong resistance to corrosion thanks to its elevated chromium and molybdenum levels. It delivers outstanding results in demanding settings, such as contact with chlorides and acidic conditions, which makes it well-suited for tough applications.
Yes,Stainless Steel 317 Flat Bar is easy to weld. Its makeup, featuring high levels of nickel and chromium, provides good weldability. That said, appropriate welding methods and preheating might be required to avoid cracking or warping in certain situations.
Stainless Steel 317 Flat Bars are frequently seen in chemical and petrochemical processing, acid handling equipment, heat exchangers, and marine applications thanks to their outstanding corrosion resistance. They work well for producing structural components, fasteners, shafts, and machinery parts that face chloride-heavy or acidic environments. On top of that, these flat bars serve the pharmaceutical, food processing, and offshore industries, where strength, durability, and the ability to withstand demanding conditions are critical. Because they pair mechanical strength with corrosion resistance, 317 Flat Bars are a reliable option for many different applications.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
