Luois Metals stands out as a leading manufacturer and supplier of Stainless Steel 1.4122 Square Bars, proudly based in Houston, USA. We’re all about quality, precision, and keeping our customers happy, which is why we provide top-notch stainless steel bars that adhere to international standards. Stainless Steel 1.4122 is a martensitic grade known for its impressive strength and decent corrosion resistance, making it perfect for various engineering and structural applications. Our square bars are crafted using cutting-edge techniques and rigorous quality checks to guarantee they’re accurate, durable, and perform consistently. At Luois Metals, we serve a range of industries, including automotive, mechanical engineering, and power generation, delivering reliable solutions throughout the U.S. and beyond.
When it comes to composition, Stainless Steel 1.4122 Square Bars mainly consist of chromium (11.0–12.5%) and carbon (0.16–0.25%), with a touch of molybdenum (0.20–0.60%) to boost hardenability and corrosion resistance. This martensitic stainless steel strikes a great balance between strength and moderate corrosion resistance. With high tensile strength typically ranging from 700 to 950 MPa, it also boasts good wear resistance and can be heat treated to further enhance its mechanical properties. These bars are easy to machine and are perfect for applications that demand hardness, strength, and some level of corrosion protection. Their mechanical performance and cost-effectiveness make them a smart choice for precision components and structural applications.

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.
Stainless Steel 1.4122 Square Bars find their place in a wide array of industrial applications where strength, hardness, and wear resistance are crucial. You’ll often see them in automotive parts like shafts and gears, as well as in mechanical components, pump shafts, and valve parts. These square bars are also great for turbine blades, power plant components, and equipment used in the oil and gas industry. Thanks to their hardenability, they’re a reliable option for demanding environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
