00Cr17Mo2 is an ultra-low carbon high-molybdenum ferritic soft magnetic stainless steel bright bar with carbon ≤0.03%, chromium 17%~19% and molybdenum 1.5%~1.8%. Trace titanium stabilizes carbon to eliminate intergranular corrosion after welding, improved soft magnetic grade equivalent to 00Cr18Mo2 and SUS444, with prominent cost advantage thanks to nickel-free composition. It delivers balanced mechanical properties, moderate tensile and yield strength, strong load-bearing capacity and excellent plasticity & deep drawability. Appropriate deformation occurs under force to avoid brittle fracture; hardness can be adjusted after annealing to meet both wear resistance and long-term anti-corrosion requirements. Molybdenum greatly stabilizes passivation film, delivering much stronger resistance to chloride ions, pitting and crevice corrosion than 00Cr17Mo1, performing steadily under salt spray, coastal humidity and mild acid & alkali environments. It features stable machinability with low tool wear during turning, milling and drilling; cold drawing & centerless grinding produce workpieces with ultra-smooth surface finish and precise dimensional accuracy. It has outstanding thermoplasticity for hot working, enabling smooth hot rolling and forging for various blanks and precision electromagnetic components. Only slight work hardening appears in cold working, ensuring stable bending and cold heading while improving surface and comprehensive mechanical performance. Featuring low coercivity and high permeability, it acts as special core raw material for solenoid valve cores, fluid control valves and seawater-resistant precision shafts, greatly extending service life of components under corrosive conditions.

Specification：1.00~300.00mm

Application: It is mainly used to manufacture moving & static solenoid valve iron cores, seawater-resistant precision shafts, fluid valve stems, instrument valve spools, heat exchanger mandrels, coastal equipment hardware, plumbing pipe joints, anti-corrosion food equipment connectors, small hydraulic valve fittings, automotive electronic control electromagnetic components, etc. Widely applied in automotive fluid solenoid valves, seawater desalination equipment, kitchen & bathroom appliances, coastal outdoor machinery, mildly acid & alkali chemical pipelines, water treatment valves, HVAC heat exchange equipment, automatic fluid control components and other industries.

Core Advantages Compared with Other Brands

1. High quality stability: Adopt complete strict production procedures and full-process online quality inspection with closed-loop control covering raw material screening to finished product delivery. Precisely control key chemical elements including carbon, chromium, molybdenum, titanium, silicon and manganese to fully meet material standards. Batch fluctuation of corrosion resistance, soft magnetism and cutting performance is negligible to guarantee consistent performance and dimension of mass-produced parts, suitable for automatic mass production.

2. Excellent surface quality: Equipped with dedicated high-precision cold drawing and centerless grinding production lines to achieve leading flatness and finish. Smooth surface reduces machining friction and improves processing efficiency, eliminates stress concentration caused by surface defects and extends component fatigue life. Exclusive passivation surface treatment strengthens anti-rust and salt-spray resistance for long-term corrosion resistance under seawater and high-chloride humid environments.

3. Ultra-high dimensional accuracy: Precision forming equipment and automatic online dimensional testing instruments narrow dimensional tolerance range. Each single bar has tiny dimensional error with extremely strong dimensional uniformity within the same batch, realizing unified part specifications during batch CNC machining and raising production yield and finished product precision.

4. Diverse product specifications: Customized 00Cr17Mo2 bright bars are available based on general market demands and customers’ special working conditions such as seawater corrosion, electromagnetic magnetism and welding requirements, fitting multiple scenarios including automobile, seawater equipment, fluid valves and chemical industry, offering personalized material selection solutions.
