Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer specializing in custom metal stampings since 1998. Our Irregularly Shaped Steel Stampings in AISI 4140 Alloy Steel, Heat Treated, Rockwell Hardness HRC 45 represent the pinnacle of precision engineering and material science. Crafted from high-grade AISI 4140 alloy steel, these stampings undergo a controlled heat treatment process to achieve a consistent hardness of HRC 45, ensuring excellent wear resistance and structural integrity. Whether you need complex geometries for automotive components or robust parts for heavy machinery, our products deliver reliable performance and long service life.
Backed by over 25 years of manufacturing experience and an annual export value of US$5–10 million, we serve clients across North America, South America, Europe, Asia, Africa, and Oceania. Our factory in Hengshui, Hebei, China, is equipped with advanced stamping presses and heat treatment furnaces, allowing us to produce intricate shapes with tight tolerances. Every piece is dimensionally inspected and hardness-tested to meet your specifications. Below we detail the key features, technical specifications, and benefits of our AISI 4140 alloy steel stampings.
Product Features & Technical Advantages
- Superior Material Strength: AISI 4140 alloy steel contains chromium, molybdenum, and manganese, offering high tensile strength and fatigue resistance. After heat treatment, the yield strength exceeds 1000 MPa.
- Precise Hardness Control: Rockwell hardness HRC 45 is achieved through a quench and temper process, providing an optimal balance of hardness and toughness – ideal for parts subject to impact and abrasion.
- Complex Irregular Shapes: Our advanced stamping dies can produce non-standard geometries, including curves, flanges, holes, and bends, with repeatability within ±0.1 mm.
- Customizable Dimensions: Thickness from 0.5 mm to 25 mm, length/width up to 600 mm, or as per your drawing. We offer both progressive die and compound die stamping.
- Optional Surface Treatments: To enhance corrosion resistance, we can apply black oxide, phosphating, zinc plating, or oil coating upon request.
- Consistent Quality: Every batch is tested for hardness, dimensional accuracy, and surface finish. Our QC system follows ISO 9001 standards (internal management).

Key Benefits for Your Application
- Extended Service Life: The combination of AISI 4140 alloy and HRC 45 hardness greatly reduces wear and tear, making these stampings perfect for high-friction environments like agricultural machinery, mining equipment, and automotive powertrain components.
- Design Flexibility: Our tooling capabilities allow us to create irregular shapes that standard stampings cannot achieve. You can submit your own CAD/2D drawing, and we will produce a die tailored to your geometry.
- Cost-Effective Production: As a direct manufacturer with decades of experience, we eliminate middlemen and offer competitive pricing for both small prototypes and large-volume orders (MOQ: 500 pcs).
- Fast Lead Times: Typical sample lead time is 7–15 working days after tooling approval; mass production takes 15–30 days, depending on quantity.
- Global Logistics Support: We ship from Tianjin, Qingdao, Shanghai, Foshan, and other major ports. Sea freight to North America and Europe typically takes 20–40 days.

Frequently Asked Questions (FAQ)
-
Q: What is the minimum order quantity (MOQ) for these stampings?
A: Our standard MOQ is 500 pieces for common sizes. For smaller quantities, we can discuss prototype samples. Please contact our sales team for exact pricing. -
Q: Can you produce stampings with a different hardness, e.g., HRC 50 or HRC 40?
A: Yes, we can adjust the heat treatment parameters to achieve a range of hardness from HRC 30 to HRC 55, depending on your application. Let us know your required hardness, and we will provide a tailored solution. -
Q: Do you offer free samples?
A: Sample policy depends on the complexity and quantity. We can provide a few samples from existing stock for evaluation. For custom samples, a nominal tooling fee is charged, which may be refundable with mass production orders. -
Q: How do you ensure the quality of heat treatment and hardness consistency?
A: Our heat treatment furnace is regularly calibrated, and we use a Rockwell hardness tester to check every batch. A test report is provided upon request. We also follow internal process control procedures to maintain uniformity. -
Q: What file formats do you accept for custom drawings?
A: We accept CAD files (.dwg, .dxf), 3D models (.stp, .iges), or PDF drawings. Our engineering team can also help convert your sketches into manufacturing-ready designs. -
Q: What is the typical lead time for tooling and first article?
A: Tooling fabrication takes 10–20 days, and first article (sample) production takes an additional 5–7 days. Mass production lead time is 15–30 days after sample approval. -
Q: Can you provide surface treatments like black oxide or zinc plating?
A: Yes, we offer multiple surface finish options. Black oxide is commonly used for corrosion resistance and improved appearance. Zinc plating is available for additional protection. Please specify your requirement during inquiry. -
Q: Do you export to my country? What are the shipping terms?
A: We export to all major markets worldwide. Our usual shipping terms are FOB Tianjin, CIF, or EXW. We can also arrange door-to-door delivery via sea or air freight. Contact us for a shipping quote to your destination.
