304 / 304L Stainless Steel Hex Bar
Stellanox Steel offers precision-engineered 304 / 304L Stainless Steel Hex Bars, known for their superior corrosion resistance, strength, and excellent machinability. These six-sided bars are ideal for high-precision components, fasteners, fittings, and structural elements used in food processing, chemical, marine, and architectural applications.
304 / 304L hex bars provide both strength and versatility, making them one of the most widely used stainless steel products in the market.
What is 304 / 304L Stainless Steel Hex Bar?
304 / 304L Stainless Steel Hex Bar is a cold-drawn or hot-rolled hexagonal bar made from austenitic stainless steel containing 18–20% chromium and 8–12% nickel. The lower carbon content in 304L minimizes carbide precipitation, enhancing weldability and resistance to intergranular corrosion.
Hex bars are especially useful in CNC machining, valve manufacturing, and bolt production, where exact dimensions and surface finish matter.
