Tianjin Emerson Metal Steel Products Co., Ltd. is proud to offer ST52 OEM Custom Precision Bending Service & Metal Fabrication Service under the EMERSONMETAL brand. As a professional metal fabrication factory, we specialize in transforming high-quality ST52 steel into custom parts through precision bending, laser cutting, welding, and other advanced processes. ST52 is a low-alloy structural steel renowned for its exceptional strength, ductility, and workability, making it a preferred choice for industries requiring reliable, high-performance components.
At the core of our service is the superior quality of ST52 steel. With a maximum carbon content of 0.22%, it balances strength and weldability—critical for fabrication processes. Its tensile strength ranges from 490 to 650 MPa, and a yield strength of ≥355 MPa ensures it can withstand heavy loads without deformation, making it ideal for structural applications. The material’s elongation rate of ≥18% provides sufficient ductility, allowing it to be bent into complex shapes (such as angles, channels, and curves) without cracking—an advantage that sets it apart from brittle high-strength steels.
Our precision bending service is a standout offering, powered by advanced CNC bending machines. These machines achieve tolerances as tight as ±0.5° for angles and ±0.1mm for dimensions, ensuring consistent results even for intricate designs. Whether bending thin sheets (0.3mm) or thick plates (up to 80mm), we use custom tooling to prevent surface damage and springback—a common issue in bending that can compromise part accuracy. For example, when fabricating automotive frames, our bending process ensures each component fits seamlessly during assembly, reducing post-processing time.
Beyond bending, we provide a full suite of fabrication services to meet end-to-end needs. Laser cutting handles material preparation with precision, cutting ST52 steel into blanks up to 2500mm in width and 12 meters in length, with a maximum thickness of 80mm. This technology delivers clean, burr-free edges, minimizing the need for secondary finishing. Welding is performed by certified technicians using methods like double-shielded arc welding and submerged arc welding, ensuring strong, durable joints that match the base material’s strength. Additional services include polishing, CNC machining, tapping, and sawing, allowing us to deliver fully finished parts ready for assembly.
Customization is central to our service. We accept OEM orders based on customer drawings, with the flexibility to produce parts in any size, shape, or quantity—from a single prototype to large-volume production (with a minimum order quantity of 1 piece for standard materials). Our quality control process includes rigorous inspections of chemical composition, mechanical properties, and dimensional accuracy, ensuring every part meets industry standards. Whether you need automotive components, construction brackets, or electronic enclosures, our ST52 fabrication service combines material excellence with precision processing to deliver reliable, cost-effective solutions.

Application Scenarios
ST52 steel, processed through our precision fabrication services, is versatile enough to serve across multiple industries, leveraging its unique combination of strength and workability:
Automotive Manufacturing: ST52 is widely used in automotive body frames, chassis brackets, and suspension components. Its high yield strength (≥355 MPa) withstands road vibrations and dynamic loads, while its ductility allows for complex bending into curved shapes (e.g., wheel arches or bumper supports). Our precision bending ensures these parts fit perfectly during assembly, reducing gaps and improving structural integrity. Additionally, ST52’s weldability simplifies joining components, making it ideal for mass-produced vehicle parts.
Construction and Infrastructure: In construction, ST52 is used for structural supports, steel frames, and architectural elements like guardrails and window frames. Its strength-to-weight ratio allows for lighter, more efficient designs compared to carbon steel, reducing material usage without compromising stability. For example, ST52 beams in high-rise buildings or bridges provide the necessary load-bearing capacity while resisting bending under heavy loads. The material’s corrosion resistance (when painted or galvanized) also ensures longevity in outdoor environments.
Electronics and Machinery: ST52 is used to fabricate enclosures, brackets, and internal components for electronic devices and industrial machinery. Its precision bending compatibility allows for tight tolerances, ensuring enclosures fit around sensitive electronics (e.g., circuit boards or sensors) without interference. In machinery, ST52 parts such as gears, shafts, and linkages benefit from the material’s toughness, withstanding repeated mechanical stress without wear or deformation.
Aerospace and Heavy Equipment: While not as lightweight as aluminum, ST52 is used in aerospace for non-critical structural parts (e.g., cargo hold frames) where strength is prioritized. In heavy equipment (e.g., cranes, excavators), ST52 components like hydraulic cylinder mounts and boom supports resist fatigue, even under continuous heavy loads, extending equipment service life.
Frequently Asked Questions (FAQ)
What makes ST52 suitable for precision bending compared to other steels? ST52’s low carbon content (≤0.22%) and high elongation (≥18%) give it excellent ductility, allowing it to be bent into tight angles or complex shapes without cracking. Unlike high-carbon steels, which are prone to brittleness, ST52 retains flexibility during bending, reducing the risk of defects. Our CNC bending machines further enhance this advantage by applying uniform pressure, minimizing springback and ensuring consistent results.
Can ST52 be used in corrosive environments, and what surface treatments do you recommend? ST52 is not inherently corrosion-resistant, but it can be adapted for mild to moderate corrosive environments with surface treatments. We recommend galvanizing (zinc coating) for outdoor applications like construction, as it forms a protective layer against rain and humidity. For industrial settings with chemicals, we offer epoxy painting or powder coating to resist mild acids and oils. For highly corrosive environments (e.g., coastal areas), we suggest combining ST52 with a stainless steel coating or upgrading to stainless steel grades.
What is the maximum size of parts you can fabricate, and how do you handle large components? We can fabricate parts up to 12 meters in length, 2500mm in width, and 80mm in thickness using our laser cutting and bending equipment. For components larger than these dimensions, we use modular fabrication—cutting and bending smaller sections that are later welded together. This method maintains precision, as each section is inspected for dimensional accuracy before assembly. Welded joints are reinforced to match the base material’s strength, ensuring the final part performs as a single unit.
What information do you need to provide a quote for custom parts? To provide an accurate quote, we require a detailed CAD drawing (preferred formats: .dwg, .dxf, .step) specifying:
Any special requirements (e.g., certification, packaging) If drawings are unavailable, we can work from sketches or samples, with our engineering team assisting to finalize specifications.
How do you ensure quality for large-volume orders? For large-volume production, we implement statistical process control (SPC), sampling parts at regular intervals to check dimensions, bending angles, and weld quality. We also conduct batch testing of ST52 material to verify consistent mechanical properties (tensile strength, yield strength) across all units. Automated laser cutting and bending systems reduce human error, while our quality team performs final inspections on 100% of parts for critical applications (e.g., automotive safety components).
