Weston Stainless, Midland, UK, is a top supplier of high-quality stainless steel products with specialization in precision-engineered components for diverse industries. Among their products, Stainless Steel 304H Sheets and Plates are extensively used due to their superior high-temperature strength, durability, and resistance to corrosion. These sheets and plates are produced from Grade 304H stainless steel, which contains higher carbon content to improve mechanical properties and structural integrity. Coming in different shapes and finishes, including hot-rolled, cold-rolled, and punched sheets, they suit different industrial applications. The 304H composition contributes to enhanced performance, and they find a perfect fit for heat exchangers, boilers, and pressure vessels.
Stainless Steel 304H Sheets and Plates contain carbon (0.04-0.10%), chromium (18-20%), nickel (8-11%), manganese (≤2%), silicon (≤1%), phosphorus (≤0.045%), and sulfur (≤0.03%) and have high-temperature strength and corrosion resistance. They possess mechanical properties like tensile strength of ≥515 MPa, yield strength of ≥205 MPa, elongation of ≥40%, and hardness of ≤201 Brinell (HB). Physical properties have a density of 8.0 g/cm³, melting point of 1400-1450°C, thermal conductivity of 16.2 W/m·K, and resistivity of 720 nΩ·m and thus are applicable in extreme heat and pressure conditions.

They come in dimensions ranging from 3mm up to 150mm thick, and up to 2000mm wide. Hot-rolled sheets are excellent in strength, ideal for structural applications.
Cold-rolled sheets have a thickness of between 0.3mm to 6mm, and their widths can reach up to 1500mm. They can give a fine surface finish, as well as very accurate dimensioning, perfect for precision applications and fabrication.
These sheets range from 1mm to 12mm in thickness. The texture on them is what gives them their anti-slip surface. They are mainly used in flooring and industrial platforms.
These sheets mainly range between 0.3mm and 12mm in thickness. Due to the uniform perforations, they are widely applied in applications such as filtration, ventilation, and decorative purposes.
The range in thicknesses for these thin sheets varies from 0.05mm to 3mm and finds applications in precise adjustments and alignment during a machinery component or structural component.
Polished sheets are available from a thickness of 0.3mm to 6mm, providing a reflective finish, and find applications in aesthetic applications and architectural designs.
Stainless Steel 304H Sheets and Plates are commonly applied in high-pressure and high-temperature applications because of their superior strength and corrosion resistance. They are required in boilers, heat exchangers, pressure vessels, and refinery piping systems to provide durability and reliability. Stainless Steel 304H Sheets and Plates are also applied in chemical processing, petrochemical, power generation, and marine industries, where oxidation and carburization resistance is important. They are also used in furnace components, aerospace parts, and food processing equipment with better mechanical properties and longer lifetimes in challenging industrial applications for heat and corrosion resistance
Stainless Steel 304H Plates and Sheets are supplied with test certificates such as Mill Test Certificate (MTC) to EN 10204 3.1/3.2, third-party inspection reports, and raw material test certificates for compliance with standards. They are safely packaged in wooden crates, pallets, or waterproof wrappings to protect them from transit damage. There is efficient and reliable delivery, with customized shipping arrangements to accommodate global industrial and commercial project demands.
