304 Stainless Steel Casting Service
304 stainless steel—often referred to as the “workhorse” of the stainless steel family—is prized for its excellent corrosion resistance, high ductility, and versatile mechanical properties. As an austenitic stainless steel, 304 is widely used in applications ranging from consumer products to heavy industrial equipment. At Dawang Metals, we specialize in providing precision 304 stainless steel casting services to meet a variety of performance requirements. Whether you’re looking for standard 304, 304L (low carbon), or 304H (high carbon) variants, our team delivers reliable, high-quality cast components that excel in demanding environments.
Key Properties of 304, 304L, and 304H Stainless Steel
304 stainless steel is composed primarily of chromium (18–20%) and nickel (8–10%), which jointly enhance its corrosion resistance and oxidation resistance. Its austenitic microstructure also provides excellent formability and weldability. Here’s a quick overview of 304 and its variants:
304 Stainless Steel
Balanced Composition: Offers the right mix of strength, corrosion resistance, and weldability for most general-purpose applications.
Common Uses: Ideal for food handling equipment, chemical containers, architectural structures, and more.
304L Stainless Steel
Low Carbon Content: Designed to minimize carbide precipitation during welding, leading to improved corrosion resistance in the heat-affected zone.
Best Choice for Welded Structures: Especially suited for large welded assemblies in corrosive environments.
304H Stainless Steel
High Carbon Content: Provides added strength at higher temperatures.
High-Temperature Performance: Recommended for applications where parts experience elevated thermal conditions.
Thanks to these variations, 304 stainless steel can accommodate a broad spectrum of project requirements—from superior weldability to enhanced high-temperature stability.

304 Stainless Steel Casting Process
304 Stainless Steel Investment Casting
We utilize silica sol investment casting to achieve precise dimensions and smooth surfaces. This process is well-suited for 304 stainless steel, as well as 304L or 304H, ensuring tight tolerances and consistent quality.
304 Stainless Steel Sand Casting
Our sand casting primarily employs resin sand and pearl sand, providing uniform particle size and robust heat resistance. Strict post-testing and recycling procedures uphold the reliability required for 304-grade castings.
304 Stainless Steel Shell Mold Casting
Our shell mold casting line, equipped with eight automated machines, can produce parts weighing up to 200 kg, with a monthly capacity of 800 tons. This system meets high-volume needs while maintaining top-tier standards for 304 stainless steel.
Post Treatments of 304 Stainless Steel Casting
Heat Treatment
We apply normalizing, annealing, and tempering to enhance 304 stainless steel’s hardness, strength, and corrosion resistance. These controlled heating and cooling cycles optimize mechanical properties and extend service life.
Post Machining
Following casting, we refine the parts with grinding, polishing, and other finishing operations to achieve strict dimensional and surface requirements. This step ensures compatibility with demanding industrial applications.
Surface Finishes
We provide various options—rust prevention oil, painting, sandblasting, chemical treatments, anodizing, and polar electrophoresis—to boost durability, improve aesthetics, and enhance the overall performance of 304 stainless steel components.
304 Stainless Steel Casting Products and Applications
304 stainless steel is an excellent choice for a broad range of industrial and commercial products. Typical applications of 304 stainless steel castings include:
Food & Beverage Industry: Components for processing equipment, mixers, and storage tanks where hygiene and corrosion resistance are paramount.
Chemical & Petrochemical: Valve bodies, pump housings, and piping systems exposed to corrosive or high-temperature conditions.
Healthcare & Medical Devices: Surgical instruments, laboratory equipment, and sterile environments requiring easy cleaning and sterilization.
Automotive & Transportation: Exhaust system components, brackets, and fasteners subjected to corrosive road conditions.
Architecture & Construction: Railings, structural supports, and decorative elements that require an attractive finish with minimal maintenance.
