Description
Top-Grade 304 Stainless Steel | Excellent Corrosion & Oxidation Resistance
Universal Austenitic Steel | Food Safe, Anti-Rust, High Toughness | Factory Supply & Custom Service
Our corrosion and oxidation resistant 304 stainless steel (AISI/SUS304) is a versatile chromium-nickel alloy. It features outstanding anti-rust performance, good workability and stable properties, ideal for industrial, food, construction, marine and medical fields. All items pass strict quality checks and support bulk order, OEM and customization.
1、Product Overview
304 (18-8 stainless steel) contains 18% chromium and 8% nickel, effectively solving rust and corrosion issues of carbon steel and low-grade stainless steel. It maintains stable performance at normal and medium-high temperatures, resisting water, weak acid, weak alkali, salt spray and common chemicals. The surface stays intact without discoloration or peeling after long-term use.
As certified food grade material, it has no harmful substance precipitation and meets global food contact standards. With great ductility, stamping and weldability, it can be made into sheets, pipes, bars and profiles, well recognized by buyers worldwide.
2、Core Advantages
✅ 1. Superior Corrosion & Oxidation ResistanceA dense protective film forms on the surface to resist atmosphere, salt spray and fresh water erosion. It works reliably in humid and coastal areas, and resists oxidation at medium temperatures, never turning yellow or deformed. It is a perfect replacement for carbon steel and inferior stainless steel.
✅ 2. Food Grade & High HygieneCompliant with global food safety standards. The smooth surface is easy to clean and sterilize with no bacteria buildup. Free of lead, cadmium and other toxins, it is a standard material for food processing, beverage production and water supply systems.
✅ 3. Good Machinability & WeldabilityThis industrial grade steel boasts excellent toughness, bending, cutting and stamping performance. Various welding methods are applicable without cracks or embrittlement. It suits complex parts, pipes and decorations to cut your processing cost.
✅ 4. High Durability & Long Service LifeHigh tensile strength and impact resistance prevent deformation, scratch and wear. It resists aging and outdoor exposure for decades with low maintenance needs, delivering great cost performance.
✅ 5. Wide Temperature AdaptabilityStable from low temperature up to 870℃. It will not turn brittle in cold environments or soften under medium heat, suitable for workshops, refrigeration equipment and outdoor facilities.
✅ 6. Full Specifications & CustomizationWe supply complete 304 products including sheets, plates, bars, seamless/welded pipes and profiles. Custom dimensions, polishing, drawing and pickling are available, as well as OEM deep processing. Both small trial orders and large bulk orders are accepted with on-time delivery guaranteed.

7、FAQ
- Q: What is the difference between 304 and ordinary stainless steel?A: As classic 18-8 chromium-nickel steel, 304 has better corrosion resistance, sanitation and processability than 201 stainless steel. It is non-magnetic and cost-effective for universal use.
- Q: Is your 304 stainless steel food grade?A: Yes. It meets international food contact standards for food equipment and kitchenware.
- Q: Can it resist salt water and outdoor oxidation?A: It works well in coastal areas and outdoor environments. Choose 316 stainless steel for severe salt water immersion.
- Q: Do you support custom size and processing?A: Yes. We provide cutting, polishing, bending, welding and non-standard customization. Feel free to send drawings for quotation.
- Q: What about lead time and MOQ?A: Standard items in stock ship within 5- 10working days; customized orders take 10-30 days. No strict MOQ required.
