00Cr19MoSPb is an ultra-low carbon molybdenum-sulfur-lead free-machining ferritic stainless steel bright bar with carbon content ≤0.03%. High chromium combined with molybdenum enhances pitting resistance and chloride corrosion resistance. Sulfur and lead work together to greatly improve machinability, and it features ferritic soft magnetic properties, widely used for precision machining of solenoid valve iron cores. It has balanced comprehensive mechanical properties, moderate tensile and yield strength, strong load-bearing capacity and excellent plasticity. It can deform appropriately under force to avoid brittle fracture. Its hardness can be flexibly adjusted after annealing heat treatment to meet both wear resistance and long-term anti-corrosion requirements. It boasts outstanding cutting performance: lead melts under cutting temperature for lubrication while sulfur optimizes chip breaking, resulting in minimal tool wear during turning, milling, drilling and automatic lathe processing, and stably produces workpieces with ultra-smooth surface finish and precise dimensional accuracy. It has good thermoplasticity for hot working, enabling smooth hot rolling and forging to fabricate various blanks and precision valve components. Only slight work hardening occurs in cold working, ensuring stable cold heading and bending while improving surface finish and overall mechanical performance. Its ultra-low carbon formula restrains intergranular corrosion after welding, and molybdenum improves salt spray and mild acid & alkali corrosion resistance. It serves as special core raw material for precision solenoid valves, fluid control valves and chemical corrosion-resistant precision shafts, greatly boosting automatic processing efficiency and component service life.

Specification：1.00~300.00mm

Application: It is mainly used to manufacture solenoid valve iron cores, fluid valve stems, corrosion-resistant precision shafts, miniature gears, stainless steel bolts & nuts, instrument valve spools, small hydraulic valve fittings, chemical micro-transmission pipes, outdoor electronic control hardware, etc. Widely applied in automotive fluid solenoid valves, household appliance control valves, precision instruments, mildly corrosive chemical equipment, water treatment valves, automatic fluid control equipment, new energy electronic 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, sulfur, lead, silicon and manganese to fully meet material standards. Batch fluctuation of cutting, soft magnetic and corrosion resistance performance is negligible to guarantee dimensional and performance consistency of mass-produced parts, providing stable raw materials 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-lasting stable performance under humid and mild chloride environments.

3. Ultra-high dimensional accuracy: Precision forming equipment and automatic 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 00Cr19MoSPb bright bars are available based on general market demands and customers’ special working conditions, fitting multiple scenarios including solenoid valves, chemical corrosion and automatic precision machining, offering personalized material selection solutions.
