Products Description
Jiangsu Cunrui Metal Products Co., Ltd. Specialized in producing high-quality 304 stainless steel welding wire. The product is made from high-quality 304 stainless steel raw materials. This product adopts advanced refining technology and precise drawing techniques. It performs exceptionally well in terms of welding performance, chemical composition stability, and mechanical performance compatibility. It is an ideal choice for welding materials in fields such as stainless steel structure welding, pressure vessel manufacturing, and pipeline installation.
This 304 stainless wire combines stable chemical composition with excellent welding fluidity and is suitable for various welding methods, including TIG (argon arc welding), MIG (gas shielded welding), and SAW (submerged arc welding).
304 stainless steel welding wire demonstrates outstanding arc stability and deposition efficiency during welding due to its precise chromium-nickel equivalent control. This 304 stainless steel welding wire features a special surface treatment process to ensure smooth wire feeding and excellent slag control. Its unique chemical composition design enables the weld metal to have matching corrosion resistance and mechanical properties with the base material, particularly suitable for applications in food equipment, chemical containers, and other scenarios with high corrosion resistance requirements.
Product features and advantages
- Excellent welding performance: The weld seam is well-formed, with little spatter and a stable welding process.
- Excellent corrosion resistance: The proportion of chromium and nickel elements remains stable, suitable for acidic and alkaline environments as well as humid conditions;
- Excellent mechanical properties: high strength, good ductility, and the weld strength is close to that of the base material.
- Smooth surface: After meticulous polishing, the surface is smooth and free of burrs.
- Wide range of applications: Compatible with various welding processes, and suitable for all kinds of stainless steel structural components, pipe fittings, and plates.

Company Introduction
We have a professional welding material production workshop, equipped with a continuous drawing line imported from Germany and a fully automatic bright annealing furnace. Through an advanced online detection system, we can monitor the diameter tolerance and surface quality of 304 stainless steel welding wire in real time. The production base is equipped with a welding process laboratory, which can simulate various working conditions for welding tests to ensure the reliability of the products in practical applications. Our technical team consists of several welding engineers, who can provide personalized product solutions according to the specific welding requirements of customers.
Quality Control
Cunrui adheres to the principle of "winning the market through quality and ensuring reputation through standards", and strictly follows international standards such as ASTM, AWS, EN, and JIS.
Before each batch of 304 stainless steel wire is put on the market, it undergoes strict testing, including:
- Chemical composition analysis;
- Tensile and elongation rate test;
- Surface finish and welding performance inspection;
- Corrosion resistance and stability inspection.
Packaging stage: Adopting international standard protective design:
- The inner layer is wrapped with moisture-proof film to prevent oxidation;
- The outer layer is wrapped with waterproof plastic film and kraft paper.
- The rewound products should be packed in wooden boxes or steel frame pallets to prevent damage during transportation.
- The labels clearly indicate the product name, specifications, material and batch number, ensuring full traceability throughout the process.
Packaging and Logistics Transportation
- Welding wire roll packaging: Standard sizes include 10kg, 15kg, and 20kg plastic or metal trays.
- Wire roll packaging: It can be done using an wrapping method or in a barrel-like container.
- Bulk export packaging: The wooden pallets are neatly stacked, covered with rainproof plastic film and securely tied together.
- Transportation method: We support sea transportation, land transportation, air transportation and express delivery transfer, ensuring the safe and punctual delivery of products to customers.
