We offer superior quality Stainless Steel 321/321H Perforated Sheets that are made from superior quality of raw materials under the supervision of our skilled professionals. These sheets are designed for the most demanding components that consistently experience temperatures in excess of 1500°F for lengthy periods of time. Their corrosion resistance is high and they can perform well in the most harsh settings such as oil & gas, chemical processing and industrial piping industries. Hence, their demand keeps increasing over time.
Perforated sheets are necessary to retain an intact overall structure, industrial applications demand uncompromising quality. To continually achieve this demanding quality standard, all our components are manufactured in complete conformity with ASTM A240 and ASME SA 240 regulations. This way we only provide the best to our clients. Our collection of standard sizes includes thicknesses from 4mm to 100mm, widths from 1000mm to 3500mm, and lengths from 2000mm to 6000 mm. We are always ready to accommodate bespoke size requests to satisfy every individual client demand.

Every Perforated Sheet of Stainless Steel 321/321H we produce is a testament to our commitment to quality. To support this we check these goods for quality features such as chemical ingredient testing, hardness profiling, material verification and service life. After passing these severe performance tests, the sheets are packed carefully into heavy-duty oak or steel boxes and protected by high-quality wrapping. This means your goods arrive undamaged, without loss in value or damage.
Selecting the proper material is critical to the safety and longevity of your high temperature infrastructure. Grades 321 and 321H are of interest because of the strength of titanium stabilization to effectively prevent intergranular corrosion and carbide precipitation over prolonged temperature exposure. This micro-alloying enables the perforated sheets to keep their mechanical integrity at temperatures up to 1500°F under constant load, providing unbelievable high temperature performance & creep strength. Together with excellent oxidation resistance, these sheets resist scaling and surface deterioration in volatile thermal conditions.
Fabricators like the better workability and weldability that makes the installation easy without post weld annealing. This structural strength means they can do a lot of different functions in many different industries. They are perfect for exhaust manifolds, heat exchangers, and chemical reactors. In addition, our precision manufacturing enables for full geometric customization and open area optimization to meet your exact filtration or airflow requirements. These grades allow plants to gain significant cost efficiency by lifespan and reduced replacement cycles. Each sheet is tested to meet rigorous quality standards & compliance such as ASTM A240 for flawless field performance.
