Tianjin Emerson Metal Steel Products Co., Ltd. is proud to offer its 439 Stainless Steel Sheet Plate CNC Customized Laser Cutting Precision Parts, a specialized solution crafted to meet the strict demands of modern industrial manufacturing. As an experienced steel factory with a full range of fabrication capabilities, we blend advanced technology, strict material control, and years of expertise to deliver precision parts that excel in performance, durability, and cost-effectiveness.
439 stainless steel, the core material of our precision parts, is a high-performance ferritic stainless steel grade developed to overcome the limitations of conventional materials. Derived from the 430 series, it has key enhancements: a reduced carbon content (max 0.03%) and the addition of titanium (Ti) as a stabilizing element. This unique composition greatly improves intergranular corrosion resistance—a crucial factor in applications exposed to high temperatures or corrosive environments—while boosting formability and weldability. Unlike many stainless steel grades, 439 strikes an excellent balance between strength and practicality: its mechanical properties are comparable to 304 in terms of strength and corrosion resistance, yet it offers a more economical alternative, making it ideal for large-scale production without sacrificing quality.
Our manufacturing process is designed to unlock the full potential of 439 stainless steel. We use state-of-the-art CNC laser cutting technology, which ensures micron-level precision in shaping complex geometries, intricate patterns, and tight tolerances. Along with our comprehensive fabrication services—including flame cutting, waterjet cutting, bending, welding, and machining—we can turn raw 439 stainless steel sheets and plates into fully finished precision parts that meet your exact specifications. Whether you need small, intricate components or large structural parts, our OEM customization service adapts to your drawings, samples, or unique design requirements, ensuring a perfect fit for your application.
We maintain strict control over the entire production chain, starting with a large stock of high-quality 439 stainless steel materials. This not only guarantees consistent quality but also enables fast delivery, as we minimize lead times related to material sourcing. Our commitment to transparency means clients are welcome to visit our factory at any stage to inspect production processes, and our dedicated after-sales service ensures ongoing support, from technical consultation to troubleshooting. With 439 stainless steel precision parts, you get a reliable, cost-effective solution that stands up to the challenges of diverse industrial environments.

Product FAQ
Q: What advantages does 439 stainless steel have over other stainless steel grades like 304?
A: 439 stainless steel offers a more cost-effective alternative to 304 while providing comparable strength and corrosion resistance in many applications. It has better intergranular corrosion resistance due to its titanium stabilization and lower carbon content, making it suitable for welding and high-temperature environments. Although its elongation is slightly lower than 304, it still maintains good formability for most fabrication processes.
