00Cr17S is an ultra-low carbon free-machining ferritic stainless steel bright bar with carbon content ≤0.03% and chromium content ranging from 16.0% to 18.0%. Sulfur is added to optimize machinability, combining the corrosion resistance of stainless steel and superior processing performance. It features balanced mechanical properties, moderate tensile and yield strength and excellent plasticity. It can deform appropriately under force to avoid brittle fracture. Its hardness can be flexibly adjusted after heat treatment to meet working conditions requiring wear resistance and mild corrosion resistance. With sulfur serving as lubricant during cutting, it greatly reduces tool wear in turning, milling and drilling, enabling ultra-smooth surface finish and precise dimensional accuracy. It has excellent thermoplasticity for hot working, supporting smooth hot rolling and forging to produce various blanks and precision finished parts. Slight work hardening occurs in cold working, yet shape and size modification can still be realized while improving surface and mechanical performance. As a key substrate for corrosion-resistant precision components, it greatly extends service life and guarantees stable operation of equipment across multiple industries.

Core Advantages Compared with Other Brands

1. High quality stability: Adopt advanced and strict complete production processes and full-process quality control system, with strict control over all links from raw material screening to finished product delivery. Precisely control the content of chemical components such as carbon, chromium, silicon and manganese to fully meet material standards. The mechanical performance fluctuation of products is extremely small to ensure consistency of products in the same batch, providing stable and reliable raw material guarantee for customers’ subsequent processing.

2. Excellent surface quality: Equipped with high-end production equipment and optimized processing technology, the bars achieve excellent flatness and finish. The smooth surface can reduce processing friction and improve processing efficiency, avoid stress concentration caused by surface defects and extend the service life of parts. The optimized supporting surface treatment process improves the rust and corrosion resistance of bars, maintaining stable performance in humid and slightly corrosive environments.

3. High dimensional accuracy: Rely on high-precision production equipment and professional testing instruments to accurately control profile sizes with narrower dimensional tolerance ranges. Each single bar has tiny dimensional error, and the dimensional difference within the same batch is extremely low with excellent dimensional uniformity. It can unify part specifications during mass automatic processing, improving production efficiency and finished product yield.

4. Diverse product specifications: Customized 00Cr13Si2 bright bars can be produced according to conventional market demands and customers’ special working conditions to adapt to a variety of complex service environments and provide customers with diversified material selection solutions.

5. Comprehensive after-sales service: The mature after-sales system can quickly respond to customer demands and feedback. Professional technical support and complete solutions will be rapidly provided for all kinds of problems encountered by customers during processing and application.
