Nestled in the heart of Addis Ababa, Tariku Metals stands as a trusted partner for Ethiopia’s growing industrial and construction sectors. We take pride in supplying robust materials built to last, and our stainless steel 1.4122 square bars are a prime example. Engineered for demanding environments, this particular grade offers a superior combination of strength and corrosion resistance, making it an intelligent choice for projects where durability and long-term performance are absolutely essential.
Stainless steel 1.4122 is known for its martensitic structure, which gives it a notable strength profile. A key part of its composition includes higher levels of carbon and a meaningful addition of molybdenum, which work together to boost its hardness and improve its resistance to pitting and corrosion. This results in a material that can be heat-treated to achieve impressive mechanical properties, including high tensile strength and good wear resistance, allowing it to stand up to tough conditions.

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.
You’ll often find this versatile steel hard at work in critical applications. Its exceptional strength and resistance to corrosion make it ideal for manufacturing components like shafts, valves, and pumps within the chemical and food processing industries. It’s also a reliable choice for essential tooling, custom machinery parts, and even architectural elements that must endure harsh weather. By choosing Tariku’s 1.4122 square bars, you’re investing in a material that delivers reliability and longevity for your most challenging projects.
