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.

Specification：1.00~300.00mm

Application: It is mainly used to manufacture corrosion-resistant shaft parts, solenoid valve iron cores, precision gears, connecting rods, stainless steel bolts & nuts, miniature half shafts, instrument valve stems, etc. Widely applied in automotive electronics, precision machinery, household appliance solenoid valves, food processing equipment, architectural hardware, measuring instruments and other fields.

Core Advantages Compared with Other Brands

1. High quality stability: Adopt complete strict production procedures and full-process quality inspection covering raw material screening to finished product delivery. Precisely control chemical elements including carbon, chromium, sulfur, silicon and manganese to fully meet national standards. Mechanical and cutting performance show negligible batch fluctuation, guaranteeing consistency of mass-produced parts and stable raw materials for long-term customer processing.

2. Excellent surface quality: Equipped with high-precision cold drawing and grinding equipment to achieve outstanding flatness and finish. Smooth surface reduces machining friction and improves efficiency, eliminates stress concentration caused by surface defects and extends component service life. Exclusive surface passivation treatment strengthens anti-rust performance for better protection in humid environments.

3. Ultra-high dimensional accuracy: Precision forming equipment and automatic testing instruments narrow dimensional tolerance range. Each single bar has tiny dimensional error, and the whole batch maintains excellent dimensional uniformity. It ensures unified part specifications during automatic mass production, raising production yield and finished product quality.

4. Diverse product specifications: Customized 00Cr17S bright bars are available based on general market demands and customers’ special working conditions, fitting various precision machining scenarios with mild corrosion and offering diversified material options.

5. Comprehensive after-sales service: Timely response to customer inquiries and processing feedback. Professional technical support and complete matching solutions will be provided promptly for all problems arising during processing and application.
