Hemi Metals, located in Hamilton, New Zealand, is a trusted manufacturer and supplier of Stainless Steel 430 Hollow Bars, designed for reliable performance in both general engineering and industrial settings. The company specializes in crafting high-quality ferritic stainless steel products that boast strong structural integrity, good heat resistance, and dependable corrosion protection in mildly aggressive environments. With cutting-edge processing systems and rigorous quality control, Hemi Metals guarantees that every 430 Hollow Bar adheres to international standards and machining requirements. Their products cater to a variety of industries where cost-effective, durable, and stable stainless steel solutions are crucial for long-term operational efficiency and equipment reliability.
Stainless Steel 430 Hollow Bars are ferritic alloys that contain about 16–18% chromium, minimal nickel, and controlled carbon content, ensuring stable corrosion resistance in indoor and mildly corrosive settings. This grade offers good oxidation resistance at elevated temperatures and maintains structural stability during thermal cycling. In terms of mechanical properties, 430 provides moderate tensile strength, adequate hardness, and acceptable ductility for forming and machining tasks. While it may not be as tough as austenitic grades, it remains a reliable choice for applications that require magnetic properties, decent heat resistance, and economical performance without needing high-level corrosion protection.

SS 430 offers good corrosion resistance in mildly corrosive environments but is less resistant than austenitic stainless steels like SS 304 or 316. It is more prone to corrosion in harsh environments, especially those with high chloride content.
SS 430 hollow bars typically range in outer diameters from 20mm to 300mm and wall thicknesses from 2mm to 30mm. Tolerances vary but are generally within ±0.5mm for diameter and ±0.2mm for wall thickness, depending on the manufacturer.
Stainless Steel 430 Hollow Bars find their place in various industries that require reliable heat resistance, moderate corrosion protection, and easy machinability. They are frequently used in household appliances, food processing equipment, kitchen fabrication, and architectural structures. Thanks to their magnetic properties, they are ideal for automotive trim, exhaust components, and interior mechanical parts. In industrial applications, 430 hollow bars are utilized for furnace components, heater tubes, and support structures, making them a versatile choice for many different settings.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
