As a leading OEM Ck15 Steel Round Bar Manufacturer & Factory, Shandong Baimaoxing Iron and Steel Co., Ltd. recognizes that precision in material science is the foundation of industrial reliability. Ck15 steel (Material No. 1.1141) is a low-carbon, case-hardening steel widely utilized in mechanical engineering and automotive components. Known for its exceptional balance of core toughness and surface hardness after carburizing, it remains a cornerstone for high-performance shafts, pins, and small gears.
Our factory implements rigorous spectroscopic analysis to ensure every batch of Ck15 meets the strict DIN 17210 and EN 10084 standards. The chemical precision of our round bars ensures predictable results during heat treatment:
| Element | Carbon (C) | Silicon (Si) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) |
|---|---|---|---|---|---|
| Content (%) | 0.12 - 0.18 | max 0.40 | 0.30 - 0.60 | max 0.035 | max 0.035 |
The low carbon content facilitates excellent weldability and forgeability, while our controlled degassing process minimizes non-metallic inclusions, significantly enhancing the fatigue life of the end products.
Our R&D department is currently integrating micro-alloying techniques using Trace elements (Vanadium and Niobium) to refine grain structures, improving the impact strength of Ck15 at sub-zero temperatures.
By 2025, we aim to provide every client with a "Digital Material Passport," simulating the exact heat treatment response of each specific heat number before the steel leaves our warehouse.
We are transitioning to Hydrogen-based reduction processes in our upstream supply chain to offer "Green Ck15," reducing the carbon footprint by 40% for our European and North American partners.
In the transition to Electric Vehicles (EVs), the demand for high-torque, lightweight shafts has skyrocketed. Our Ck15 Steel Round Bar offers the perfect substrate for precision-ground components that require high dimensional stability.
The "Industry 4.0" wave requires robots with high repeatability. We provide Ck15 bars with specialized cold-drawn finishes (h9, h10, h11 tolerances) to ensure seamless integration into automated CNC lathe feeding systems.
From solar tracker pivots to wind turbine secondary fasteners, the reliability of our case-hardened steel ensures structural integrity in harsh environmental conditions.
Shandong Baimaoxing leverages "Smart Factory" integration to ensure 100% traceability and efficiency.
Automated Ultrasonic Testing (UT) and Eddy Current Testing (ET) integrated into the production line to detect internal defects and surface cracks in real-time.
Our ERP system uses machine learning to predict lead times based on global shipping congestion data, ensuring our OEM partners never face a line-down situation.
Whether you require specific lengths (cut-to-size), custom heat treatment (Normalizing, Annealing, or Quenching), or specialized surface coatings, our agile production lines adapt instantly.
Full compliance with EN 10084, providing 3.1 or 3.2 Material Test Certificates (MTC) with every shipment.
Cross-referenced equivalents for SAE 1015, ensuring engineers can specify our products in US-designed projects.
ROHS and REACH compliant. We ensure our chemical handling and waste management exceed international environmental safety benchmarks.

Ck15 is a case-hardening steel with lower carbon content, making it much easier to weld and cold-form. It is designed to be carburized to create a hard wear-resistant surface while maintaining a tough, ductile core, whereas C45 is a medium-carbon steel used for quenching and tempering for uniform hardness.
Yes, our factory specializes in precision cold-drawing. we can provide tolerances from h9 to h11 for seamless integration into automatic machining centers.
Absolutely. We regularly work with SGS, BV, and Lloyd's Register to provide independent verification of chemical and mechanical properties for our global clients.
