Hemi Metals stands out as a reliable manufacturer and supplier of top-notch Stainless Steel 347 Hex Bars, catering to various industries in Hamilton, New Zealand, with precision-engineered stainless steel solutions. These hex bars are celebrated for their exceptional corrosion resistance, heat stability, and durability, all produced under stringent quality standards to withstand tough industrial conditions. Hemi Metals merges cutting-edge manufacturing techniques with a customer-centric approach, guaranteeing consistent performance, reliable supply, and lasting value. With a strong dedication to excellence, the company supports sectors like engineering, fabrication, and processing by providing Stainless Steel 347 Hex Bars that thrive in both high-temperature and corrosive environments.
Stainless Steel 347 Hex Bars are enhanced with niobium to boost their resistance to intergranular corrosion, particularly after welding or when exposed to high temperatures. Their typical composition includes chromium, nickel, carbon, manganese, silicon, phosphorus, sulfur, and niobium as stabilizers. These bars deliver impressive tensile and yield strength, good creep resistance, and robust oxidation resistance at elevated temperatures. The alloy maintains its structural integrity during thermal cycling, preventing carbide precipitation and ensuring long-lasting durability. This well-rounded mix of corrosion resistance, heat tolerance, and mechanical strength makes Stainless Steel 347 Hex Bars perfect for demanding applications.

SS 347 Hex Bars are widely used in aerospace, chemical processing, and power generation for applications requiring high-temperature resistance, corrosion resistance, and strength. They outperform other grades due to their niobium stabilization, preventing carbide precipitation and ensuring durability.
SS 347 Hex Bars typically exhibit a tensile strength of 515-750 MPa, a yield strength of 205 MPa, and an elongation of 40% minimum. These properties ensure high durability, flexibility, and performance in demanding applications.
SS 347 Hex Bars commonly comply with standards like ASTM A276, ASTM A479, ASME SA479, and AMS 5646. These certifications ensure quality, dimensional accuracy, and performance for high-temperature and corrosion-resistant applications across industries, meeting stringent safety and reliability requirements.
These hex bars find extensive use in industries that require reliable performance under high heat and corrosive conditions. They are particularly suited for chemical processing systems, heat exchangers, refinery equipment, and furnace components due to their strong resistance to intergranular corrosion. The alloy is also utilized in aerospace fittings, power generation components, high-temperature gaskets, and expansion joints. Additionally, food processing, pharmaceutical equipment, and marine structures benefit from its cleanability and durability. With excellent thermal stability, these hex bars are a go-to choice for a variety of challenging environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
