30CR13 SS Plain Washers
Product Overview
30CR13 SS Plain Washers are high-strength, corrosion-resistant flat washers made from martensitic stainless steel 30CR13. Designed to provide a smooth bearing surface under bolt heads and nuts, these washers distribute loads more evenly, reduce surface wear, and prevent surface deformation. Their high tensile strength and rust-resistant properties make them especially useful in harsh or high-temperature environments. At Flybear Fastener, we manufacture 30CR13 SS Plain Washers with exceptional dimensional accuracy and consistent quality across batches.

Material Overview & Manufacturing Process
30CR13 is a martensitic stainless steel known for its hardened structure achieved through heat treatment. It contains chromium content (~13%) that delivers corrosion resistance and enhanced mechanical properties.
Manufacturing involves:
- Raw material checking and selection
- Precision blanking and stamping
- Heat treatment to improve hardness
- Surface cleaning and inspection
- Dimensional inspection and packaging
All washers are manufactured under strict quality control protocols to ensure superior mechanical performance and dimensional stability.
Common Applications and Industrial Use Cases
30CR13 SS Plain Washers are widely applied in:
- Petrochemical installations
- Industrial machinery
- Marine hardware
- Aerospace components
- Automotive manufacturing
- Power generation equipment
Their durability and corrosion resistance make them the washer of choice in environments exposed to moisture, chemicals, or high mechanical stress.
Product Advantages & Competitive Edge
Material Selection
Made with high-strength 30CR13 stainless steel, these washers offer excellent wear resistance, hardness, and long service life.
Precision Manufacturing
Using advanced CNC stamping and tight-tolerance machining, 30CR13 SS Plain Washers are engineered with consistent thickness and accurate inner/outer diameters.
Surface Treatment
While the washers are plain (non-coated), they leverage the natural corrosion protection of 30CR13, and additional surface cleaning ensures smoothness and appearance.
Customization Capabilities
Whether by drawing or sample, Flybear Fastener provides full customization support in shape, size, and tolerances.
Sufficient Inventory
We maintain a well-stocked warehouse with efficient packaging and logistics systems to ensure quick delivery anywhere in the world.
After-Sales & Technical Support
Our technical team offers fast response and expert guidance in application and installation.
Company Testing & Quality Control
Quality is our cornerstone. At Flybear Fastener, testing includes:
- Hardness Testing (Rockwell and Brinell)
- Tensile Strength Testing
- Dimensional Fidelity Inspection
- Salt Spray Testing (accelerated corrosion test)
- Surface Roughness and Flatness Verification
Each batch of washers undergoes sampling & batch control to comply with international standards like ISO 9001 and customer-specific requirements.
Product Selection & Procurement Guide
When selecting 30CR13 SS Plain Washers, consider:
- Bolt diameter and washer internal diameter compatibility
- Intended application load and required material hardness
- Operating environment (corrosive? high-temperature?)
- Thickness and OD (Outer Diameter) requirements
- Conformance to standards (DIN, ISO, JIS)
Ensure you procure from certified manufacturers like Flybear Fastener to secure consistent product quality. For bulk orders or custom requirements, contact our sales team for technical consultation and support.
