Situated in the heart of Manama, Bahrain, Niazi Stainless has built a reputation as a trusted partner for industry, specializing in high-performance materials. We take particular pride in our supply of SS 422 sheets and plates, a martensitic stainless steel known for its impressive strength and reliability. This grade is a go-to solution for engineers and fabricators facing demanding environments where ordinary steels fall short, offering a perfect balance of durability and corrosion resistance that stands up to tough challenges.
The composition of SS 422 is carefully balanced, with chromium providing its core corrosion resistance, while significant additions of molybdenum and nickel enhance its strength and toughness. This alloy is specifically heat-treated to achieve remarkable mechanical properties, resulting in a material that offers high tensile strength and excellent hardness. This combination makes it exceptionally resistant to wear and tear, ensuring components made from our SS 422 plates can withstand substantial stress and impact over a long service life.

SS 422 cold rolled sheets are stainless steel material that is strong, durable, and furnished with a smooth surface. These sheets are available in various thicknesses, from 0.1mm to 6mm and can be manufactured with the desired width and length for any industrial usage.
SS 422 chequered plates are highly durable stainless steel sheets with a raised design that increases grip and limits slipping. Used for flooring, walkways, and other industrial applications, chequered plates vary in sizes but are usually 2mm to 8mm thick.
SS 422 perforated plates are stainless steel sheets designed with precision holes for industrial use. The durability and corrosion resistance of these plates are excellent and usually available in sizes from 0.5mm to 12mm in thickness and in a customizable hole pattern, making them versatile in performance.
These are thin sheets in stainless steel 422, precision engineered to withstand excellent corrosion resistance and high temperatures. They are usually found in sizes 0.1mm to 5mm in thickness. There is always a need to make precise alignment and gap filling in several industrial applications.
SS 422 Polished Plates are most resistant to corrosion yet very strong and offer a finishing finish quality. Known to be of high quality, the plates vary in size, and may differ in thickness that can range from 3mm up to 100mm, thus giving versatility to various industries.
Niazi Stainless is committed to delivering a seamless customer experience by providing complete documentation for the Stainless Steel 422 Sheet and Plate products, ensuring top-notch quality. Commercial invoice, packing list, fumigation certificate, heat treatment chart, quality assurance plans, and NABL-approved lab test reports are given from Niazi Stainless. These papers are proof of our authenticity and superior quality products. Furthermore, we provide test certificates for our Stainless Steel 422 Sheets and Plates, which include MTC as per EN 10204/3.1b, PMI Test Certificates, 100% radiography test reports, and Third-Party Inspection Certificates, which demonstrate our customer-centric approach and excellence.
The robust nature of SS 422 sheets and plates makes them indispensable in heavy-duty industries. You’ll commonly find this material in critical components like turbine blades, compressor parts, and high-stress fasteners within the power generation sector. It’s also widely used for constructing knife blades, shafts, and valves, especially in applications involving elevated temperatures or mildly corrosive environments. Its reliability makes it a preferred choice for everything from industrial machinery to specialized tooling, providing a lasting solution where failure is not an option.
