Yes, Stainless Steel 1.4122 flat bars can be welded, though preheating and post-weld heat treatment may be necessary to reduce the risk of cracking and ensure optimal weld quality.
Yes, Stainless Steel 1.4122 flat bars can be heat treated. It is typically hardened by quenching and tempering, allowing control over hardness and strength for specific applications.
Stainless Steel 1.4122 flat bars resist corrosion due to their high chromium content, forming a passive oxide layer that protects the material from oxidation and corrosion in various environments.
These flat bars find extensive use in creating pump shafts, turbine blades, valves, fasteners, machine parts, and automotive components. Their resistance to wear and fatigue makes them particularly ideal for mechanical and structural applications in power plants, oil and gas equipment, and general engineering. Additionally, these flat bars are utilized in industrial tools and instruments that require a blend of hardness, durability, and corrosion resistance. Their versatility and performance under pressure make 1.4122 flat bars a highly valuable material in 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.
