Operating from the heart of Kinshasa, Mbemba Stainless stands as a trusted partner for industry across the Congo, dedicated to providing robust and reliable materials. We take pride in our specialized supply of SS 422 sheet and plates, a high-strength martensitic stainless steel chosen for its exceptional durability. Our commitment is to ensure that local engineers and manufacturers have direct access to this premium-grade material, supporting the growth and integrity of projects that demand unwavering performance under the most challenging conditions.
The strength of SS 422 lies in its specific composition, which includes a careful balance of chromium and additional elements like molybdenum and tungsten. This alloy recipe gives the material its notable mechanical properties, including a very high tensile strength and excellent hardness. It is specifically heat-treated to achieve these robust characteristics, making it significantly stronger than many other stainless grades while still maintaining good corrosion resistance, particularly in mild atmospheres and fresh water.

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.
Mbemba 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 Mbemba 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.
This unique combination of strength and corrosion resistance makes SS 422 sheet and plate ideal for demanding applications. You will often find it being used in critical components like turbine blades, fasteners, and high-stress parts within pumps and valves. Its ability to withstand significant mechanical stress makes it a go-to material for the aerospace, power generation, and specialized manufacturing sectors, where failure is not an option and longevity is paramount for safety and efficiency.
