304H / 304N / 304LN Stainless Steel Bar & Rod
Product Overview
304H, 304N1, 304N2, and 304LN stainless steel bars and rods are austenitic stainless steels designed for enhanced strength, corrosion resistance, and high-temperature performance. Compared with standard 304 grades, nitrogen and controlled carbon content improve mechanical properties and structural stability, making them suitable for demanding industrial environments.
Voyage Metal supplies stainless steel bars and rods with stable quality, strict chemical control, and flexible customization to meet international industrial standards.

FAQ
What is the difference between 304H and standard 304?
304H contains higher carbon content, providing better strength and creep resistance at elevated temperatures.
Why choose 304N or 304LN stainless steel bars?
Nitrogen-enhanced grades offer improved yield strength and better resistance to intergranular corrosion, especially after welding.
Can Voyage Metal supply custom sizes?
Yes. We offer customized diameters, lengths, and surface finishes according to your project requirements.
