SUS 403 seamless stainless steel tube (UNS S40300, American AISI/ASTM standard) corresponds to the Chinese grade 12Cr12. It is a martensitic stainless steel with 12% chromium as the main alloying element, and its carbon content is usually controlled below 0.01% (the specific value is subject to actual detection). Through precise chemical composition ratio and heat treatment process, this material shows excellent high-temperature stability and mechanical strength, can maintain oxidation resistance in a continuous high-temperature environment, and resist fatigue loss under high stress conditions. It is particularly suitable for turbine blades, rotors, high-temperature fasteners and key pressure-bearing components in energy equipment. The passivation film formed by its chromium element can effectively resist atmospheric and water vapor corrosion, take into account the durability requirements in industrial environments, and support forging, cutting and other processing methods to flexibly adapt to different design requirements. This product complies with the international standards of ASTM A213/A269 (seamless pipe) and ASTM A249 (welded pipe), and is widely used in high-load scenarios in the fields of power, chemical industry and aviation. It is the preferred material that takes into account performance and reliability under high temperature, high pressure and corrosive conditions. In practical applications.Product test report provided by SUS403 seamless stainless steel tube manufacturers for reference.
SUS 403 seamless stainless steel tube has 12% chromium as the core component and carbon content ≤0.01% (the actual content is subject to testing), and is a martensitic stainless steel. By optimizing the composition and heat treatment process, it has high-temperature oxidation resistance, high mechanical strength (fatigue resistance and hardness) and moderate corrosion resistance (chromium passivation film protection), strong machinability, and supports forging, cutting and other processes. Designed for high temperature and high stress scenarios, it is widely used in turbine blades, energy equipment fasteners, chemical and aviation high-load components, and complies with international standards such as ASTM A213/A269. It is a reliable material in high temperature, high pressure and corrosive environments.

PRODUCTION PROCESS
Hot rolled (extruded stainless seamless steel pipe): round tube billet → heating → piercing → three-roller oblique rolling, continuous rolling or extrusion → tube removal → sizing (or reducing diameter) → cooling → billet tube → straightening → water pressure test (or flaw detection) → marking → storage.
