Phehlukwayo Metal, located in Cape Town, South Africa, stands out as a top manufacturer and supplier of stainless steel products, with a particular focus on Stainless Steel 1.4122 Square Bars. Known for their commitment to quality, precision, and reliability, this company caters to a variety of industrial sectors, including manufacturing, construction, and engineering. Phehlukwayo Metal is dedicated to providing durable, heat-treatable stainless steel materials that adhere to strict standards and meet customer specifications. With an emphasis on outstanding service and prompt delivery, they have built a solid reputation as a trusted supplier in both regional and international markets.
Stainless Steel 1.4122 Square Bars are crafted from a martensitic stainless steel alloy that contains around 0.39% carbon, 16.5–18.5% chromium, and 0.8–1.3% molybdenum. This unique blend results in remarkable hardness, strength, and moderate resistance to corrosion. The steel is highly amenable to heat treatment, which enhances its mechanical properties, allowing for tensile strength of up to 900 MPa and improved wear resistance. These characteristics make Stainless Steel 1.4122 perfect for applications that require durability and toughness in moderately corrosive 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.
You’ll find Stainless Steel 1.4122 Square Bars commonly used in situations that demand high strength, wear resistance, and protection against corrosion. They’re ideal for manufacturing shafts, fasteners, turbine blades, and various mechanical components in the automotive, aerospace, and energy sectors. Their impressive hardness and heat-treatability also make them suitable for tools, knives, and precision instruments. With a balanced mix of mechanical strength and corrosion resistance, these square bars deliver reliable performance even in the most challenging engineering and industrial environments.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
