Sadiki Metals, based in Kinshasa, Congo, stands out as a top manufacturer and supplier of high-quality Stainless Steel 1.4122 Square Bars. These bars are celebrated for their remarkable quality, precision, and durability. The company employs cutting-edge production techniques and top-notch raw materials to ensure that their products adhere to strict international standards. Known for their impressive strength, machinability, and resistance to corrosion, Sadiki Metals’ Stainless Steel 1.4122 Square Bars are perfect for a variety of industrial uses, including engineering, automotive, machinery, and construction projects both in Congo and around the globe.
These square bars are made from martensitic stainless steel, which contains about 11–13% chromium, 0.2–0.4% carbon, along with trace amounts of molybdenum, manganese, and silicon. This unique blend gives them high hardness, excellent wear resistance, and decent corrosion resistance, particularly after heat treatment. The alloy boasts tensile strengths between 700 and 950 MPa and maintains excellent dimensional stability. It’s also easy to machine and polish, making it a great choice for precision-engineered components. Additionally, Stainless Steel 1.4122 offers moderate resistance to oxidation and scaling in mildly corrosive or high-temperature settings.

Yes, Stainless Steel 1.4122 square bars can be heat treated. They are typically hardened and tempered to enhance strength and wear resistance, with tempering temperatures ranging between 200°C and 400°C depending on desired properties.
Consider factors like required strength, corrosion resistance, wear resistance, application environment, dimensional accuracy, thermal properties, compliance with industry standards, and suitability for machining or heat treatment when choosing Stainless Steel 1.4122 square bars.
Yes, Stainless Steel 1.4122 square bars can be welded, but they require preheating to around 200-300°C and post-weld heat treatment to reduce residual stresses and maintain mechanical properties.
Sadiki Metals’ Stainless Steel 1.4122 Square Bars are widely utilized in applications that require strength, hardness, and wear resistance. They are perfect for crafting shafts, spindles, bolts, and mechanical parts in the automotive and machinery sectors. Moreover, they find use in pump parts, valve components, and tools that need to withstand mechanical stress. The construction and engineering industries also rely on these bars for structural elements and equipment that function in moderately corrosive environments. With their outstanding machinability and toughness, they are a go-to choice for precision fabrication and various industrial applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
