Poang Fasteners is a leading manufacturer, supplier and exporter specializing in high-quality stainless steel 304H bolts. We offer premium bolts designed to meet stringent industry standards, ensuring excellent performance and durability in harsh applications. Our commitment to quality assures that every bolt is designed to the highest standards, providing a reliable solution for various industrial requirements.
Stainless Steel 304H Bolts are produced from an 18–20% chromium and 8–10% nickel-containing austenitic alloy that has a higher percentage of carbon for enhanced strength as well as thermal resistance. The composition provides better mechanical performance through enhanced tensile strength, creep resistance, and durability at high temperatures. The bolts have superior resistance to oxidation as well as general corrosion and, therefore, can be used confidently in aggressive industrial applications. With high toughness, weldability, and service life, 304H bolts are suitable for holding significant equipment and ensuring structural stability under mechanical load and corrosive attack alike.

Stainless Steel 304H Bolts have extensive applications in industries demanding strength, resilience, and corrosion resistance at elevated temperatures. In chemical processing plants, they are utilized in pipelines, flanges, and reactors subject to severe chemicals. In the generation of power, they are employed in heat exchangers, turbines, and boilers to provide safe and long-lasting operation. In petrochemical plants, they stabilize equipment in extremely high temperatures and corrosive conditions. They are also applied in air purification systems and industrial insulation techniques where reliability and resistance against oxidation are essential. Their capability to work in rigorous conditions provides lasting durability and safety.
In Poang Fasteners, our Stainless Steel 304H Bolts are tested rigorously to ensure high quality and reliability. Testing involves hardness tests, spectrochemical testing, Positive Material Identification (PMI), levelling, micro–macro inspection, pitting resistance tests, flare tests, and intergranular corrosion (IGC) analysis. All shipments are followed by comprehensive documentation such as commercial invoices, packaging lists, certificates of origin, and trade compliance documentation. As a further guarantee, we issue third-party inspection certificates and full test reports, guaranteeing compliance with international standards. Bolts are carefully packaged to avoid transit damage so that products reach our customers in their original condition, ready to use immediately in industry.
