Tianjin Emerson Metal Steel Products Co., Ltd. is proud to offer SUS304 Metal Sheet Laser Cutting Parts & Stainless Steel Waterjet Cutting Service under the EMERSONMETAL brand. As a professional sheet metal fabrication factory, we specialize in transforming high-quality SUS304 stainless steel into precision parts using advanced laser cutting and waterjet cutting technologies. SUS304 is a widely recognized austenitic stainless steel grade, celebrated for its exceptional corrosion resistance, excellent formability, and impressive mechanical properties—making it a versatile choice for industries ranging from food processing to automotive manufacturing.
At the core of our service is the superior quality of SUS304 stainless steel. This grade belongs to the 18Cr-8Ni alloy series, where chromium (18-20%) forms a protective oxide layer on the surface, preventing rust and corrosion, even in humid or mildly corrosive environments. Nickel (8-10.5%) enhances its ductility and toughness, allowing the material to be easily shaped, bent, or welded without losing structural integrity. With a tensile strength of ≥520 MPa and elongation of ≥40%, SUS304 strikes a perfect balance between strength and flexibility, making it suitable for both structural components and precision parts.
Our fabrication process combines two advanced cutting technologies to meet diverse needs: laser cutting and waterjet cutting. Laser cutting is ideal for thin to medium thickness sheets (0.5mm–20mm), delivering unparalleled precision with tolerances as tight as ±0.1mm. It produces clean, burr-free edges, reducing the need for secondary finishing—critical for parts requiring seamless assembly, such as kitchen equipment or automotive components. For thicker sheets (20mm–100mm) or materials sensitive to heat, we use waterjet cutting, a cold-cutting method that uses high-pressure water mixed with abrasives to cut through steel without generating heat. This avoids thermal distortion, preserving the material’s corrosion resistance and mechanical properties—essential for heavy-duty applications like chemical processing equipment.
Beyond cutting, we offer comprehensive post-processing services to enhance functionality and aesthetics. This includes bending to create custom angles, welding for assembly into larger structures (using TIG or MIG welding to maintain joint strength), and surface treatments such as passivation to boost corrosion resistance. Customization is a cornerstone of our service: we accept OEM orders based on customer drawings, with the flexibility to produce parts in any size or shape—from small washers to large structural panels. Whether you need a single prototype or bulk production, we accommodate orders starting from 1 piece, with strict quality control at every stage. From material inspection (verifying chemical composition and mechanical properties) to final dimensional checks, we ensure every part meets the highest standards of reliability and performance.

Application Scenarios
SUS304 stainless steel parts, fabricated via our laser and waterjet cutting services, are designed to excel in diverse industrial environments, leveraging their unique material properties:
Food Processing and Catering: SUS304 is the gold standard for food-grade equipment, thanks to its non-toxic nature, smooth surface (resistant to bacterial growth), and easy cleanability. Our precision-cut parts are used in food processing machines (mixers, conveyors), kitchen utensils (stainless steel tables, sinks), and storage containers. The material’s corrosion resistance ensures it remains unaffected by food acids, salt, or cleaning agents, maintaining hygiene and safety.
Building and Decoration: In construction, SUS304 parts are used for interior and exterior decoration—including handrails, elevator panels, and facade cladding. Its sleek appearance, combined with resistance to weathering and rust, ensures long-term aesthetic appeal. For example, polished SUS304 handrails in shopping malls or airports retain their luster even with heavy foot traffic, while exterior cladding withstands rain, humidity, and UV exposure without degradation.
Chemical and Pharmaceutical Industries: SUS304’s resistance to mild acids, alkalis, and organic solvents makes it ideal for chemical storage tanks, piping systems, and reactor components. Our waterjet-cut parts (for thick-walled pipes or pressure vessels) maintain structural integrity even when transporting corrosive fluids, ensuring safe operation in petrochemical plants or pharmaceutical facilities.
Automotive and Marine Engineering: In automotive manufacturing, SUS304 is used for exhaust system components, trim parts, and fuel line brackets—its corrosion resistance protects against road salt and moisture. In marine applications, it serves as hull fittings, propeller shafts, and deck hardware, withstanding saltwater exposure far better than carbon steel, thus reducing maintenance needs.
Medical and Laboratory Equipment: The material’s biocompatibility and easy sterilization make it suitable for medical devices such as surgical instrument trays, laboratory benches, and diagnostic equipment housings. Laser-cut precision ensures these parts meet strict dimensional requirements for seamless assembly and safe use.
Frequently Asked Questions (FAQ)
What is the difference between laser cutting and waterjet cutting for SUS304, and how do I choose? Laser cutting is ideal for thin to medium sheets (0.5mm–20mm) requiring high precision (±0.1mm) and clean edges—perfect for parts like kitchen components or automotive trim. Waterjet cutting is better for thicker sheets (20mm–100mm) or heat-sensitive applications, as it avoids thermal distortion. Choose laser cutting for intricate shapes and cost efficiency; opt for waterjet cutting for thick, heavy-duty parts or when heat might compromise material properties.
Is SUS304 suitable for high-temperature applications? Yes, SUS304 can withstand continuous operating temperatures up to 870°C (1600°F) in oxidizing environments, making it suitable for ovens, industrial furnaces, and exhaust systems. However, prolonged exposure to temperatures above 425°C (800°F) may slightly reduce its corrosion resistance. For applications exceeding 870°C, we recommend consulting our technical team for material alternatives or protective coatings.
How does SUS304 perform in saltwater or coastal environments? SUS304 offers good resistance to saltwater spray and coastal humidity, making it suitable for marine hardware, coastal building facades, and outdoor furniture. While it is more corrosion-resistant than carbon steel, it may develop minor rust in highly saline environments (e.g., direct saltwater immersion). For such cases, we offer passivation or electropolishing treatments to enhance the protective oxide layer, extending service life.
Can you produce large-sized SUS304 parts, and what are the size limits? Yes. Our laser cutting machines can handle sheets up to 3000mm × 1500mm, and waterjet cutting supports even larger sizes with custom setups. For parts exceeding standard sheet dimensions, we can weld smaller sections with precision, ensuring structural integrity. Contact us with your specific size requirements, and we will provide a tailored solution.
What is the lead time for custom SUS304 parts, and can you handle urgent orders? Lead time depends on complexity and quantity. For simple laser-cut parts (1–50 pieces, 0.5mm–10mm thick), delivery takes 3–5 working days. For waterjet-cut parts (thicker than 20mm) or large orders (100+ pieces), lead times extend to 7–10 working days. Urgent orders can be expedited: small batches (1–10 pieces) with simple designs can be completed in 2–3 working days for an additional fee. We confirm timelines after reviewing your drawings.
