00Cr20Mo2 is an ultra-low carbon high-chromium molybdenum stabilized ferritic stainless steel bright bar with carbon ≤0.025%, chromium 19.0%~21.0% and molybdenum 1.75%~2.50%. Trace titanium/niobium is added to fix carbon and eliminate intergranular corrosion after welding. It is an upgraded high-corrosion-resistance ferritic stainless steel with nickel-free composition, much more cost-effective than 316L and 904L austenitic stainless steel.
It delivers balanced comprehensive mechanical properties, moderate tensile and yield strength, stable load-bearing capacity, excellent plasticity, deep drawing and cold heading formability. Appropriate deformation occurs under force to avoid brittle fracture; its hardness can be flexibly adjusted after annealing for long-term stable wear resistance. The high-chromium & high-molybdenum alloy system forms dense and stable passivation film, delivering far superior resistance to pitting, crevice corrosion, chloride ions, salt spray, seawater and mild acid & alkali media compared with 00Cr17Mo2 and 00Cr18Mo2, greatly extending service life in coastal, water treatment and mildly corrosive chemical environments.
It features excellent machinability with low tool wear during turning, milling, drilling and CNC automatic lathe processing. Cold drawing and centerless precision grinding stably produce workpieces with ultra-high surface finish and precise dimensional accuracy. It boasts good thermoplasticity for hot working with smooth hot rolling and forging for various corrosion-resistant precision blanks, valve bodies and electromagnetic components. Only slight work hardening appears in cold working to ensure stable bending and cold heading while improving surface finish and overall mechanical performance.
With soft magnetism of low permeability, low linear expansion coefficient and outstanding resistance to chloride stress corrosion cracking, it serves as premium special raw material for seawater equipment, water treatment valves, chemical corrosion-resistant precision shafts and solenoid valve iron cores.

Specification：1.00~300.00mm

Application:It is mainly used to manufacture seawater-resistant precision shafts, seawater valve stems, water treatment valve spools, moving & static solenoid valve iron cores, coastal equipment hardware, corrosion-resistant heat exchanger mandrels, chemical micro-transmission pipes, anti-corrosion food equipment connectors, high-strength stainless steel bolts & nuts, small marine hydraulic valve fittings, etc. Widely applied in seawater desalination equipment, coastal outdoor machinery, environmental water treatment valves, marine auxiliary machine parts, food anti-corrosion equipment, mildly acid & alkali chemical devices, HVAC seawater heat exchange equipment, automotive fluid electronic control solenoid valves and other industries.

Core Advantages Compared with Other Brands

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

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 service life. Exclusive enhanced passivation treatment greatly boosts salt spray and seawater corrosion resistance for long-term rust-free performance under 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 effectively raising production yield and finished machining precision.
