Our stainless steel hex bars are available in a variety of grades including 303, 304L, 316L, 316Ti, 321, 409, 410, 430F, 17-4 PH/630, and other austenitic, ferritic, martensitic, and duplex steels—each tailored to meet specific engineering needs. Whether for structural frameworks or high-performance components, our hex bars are produced to meet international quality standards and customer-specific requirements.
The strength and corrosion resistance of our stainless steel hex bars come from their chemical composition and metallurgical properties. For example, Grade 304 Hex Bar contains 18% chromium and 8% nickel, delivering excellent tensile strength and moderate resistance to general corrosion. On the other hand, Grade 316 Hex Bar includes 16% chromium, 10% nickel, and 2% molybdenum, which offers enhanced protection in chloride-rich and marine environments. Austenitic stainless steels are especially favored for their toughness and formability, making them suitable for a wide range of demanding applications.
At Mukund Steels, we also offer customization options in size, shape, and finish, ensuring that our stainless steel hex bars align perfectly with your specific project or application. Backed by decades of metallurgical expertise and advanced manufacturing capabilities, Mukund Steels continues to deliver stainless steel solutions that stand the test of time.
