The 440C and 440B stainless steel flat bars are martensitic high-carbon grades designed for demanding applications where hardness and wear resistance are critical. Supplied by Jiangsu Steel Group Co., Ltd. from China, these bars deliver moderate corrosion resistance alongside exceptional durability, with 440C achieving maximum hardness through heat treatment. The material composition is martensitic stainless steel, specifically grades 440C and 440B, meeting ASTM A276 and AISI standards for engineering-grade performance.
Both grades are widely used in manufacturing sectors requiring precision and longevity. 440C is preferred for surgical instruments, high-end cutlery, and bearings due to its superior edge retention, while 440B offers a balanced combination of toughness and corrosion resistance for pump components and industrial valves. Typical industry standards for these grades include a carbon content of 0.95% to 1.20% for 440C and 0.75% to 0.95% for 440B, with chromium levels around 16-18% to ensure corrosion resistance. These bars are supplied in standard widths and thicknesses, with typical tolerances of ±0.1 mm for precision applications.
Industrial buyers source these flat bars for applications in automotive, aerospace, and machinery manufacturing, where resistance to abrasion and fatigue is essential. Jiangsu Steel Group Co., Ltd. exports globally, with packaging options including bundles or pallets to suit bulk shipments. Buyers should confirm dimensions, surface finish, and heat treatment requirements to match their fabrication needs. The material’s suitability for machining and polishing makes it a versatile choice for both structural and decorative uses in high-stress environments.

Before ordering, verify the exact chemical composition and mechanical properties of the 440C and 440B flat bars, as these directly impact performance in your application. Request mill test certificates to confirm compliance with ASTM A276 and AISI standards, and ensure the material has undergone the necessary heat treatment for your intended use. Inspect the surface finish and dimensional tolerances to avoid discrepancies in fabrication.
Confirm logistics details such as lead time, shipping method, and Incoterms with Jiangsu Steel Group Co., Ltd. to align with your production schedule. Typical lead times for stainless steel flat bars can vary based on stock availability and custom requirements, so clarify these early. Discuss payment terms, such as L/C or T/T, and ensure they are feasible for your procurement process.
Conduct quality checks upon receipt to verify the flat bars meet the specified dimensions, surface finish, and hardness. Use calipers to measure tolerances and hardness testers to confirm the material’s properties. Request documentation such as material test reports and certificates of compliance to ensure traceability and adherence to industry standards.
