304 Stainless Steel Plate Hot Rolled Stainless Steel Sheet Anti Corrosion ASTM Standard

The product fully complies with the requirements of ASTM A240/A480 (the core ASTM standard for flat-rolled stainless steel plates and sheets), with the corresponding grade of 304 (UNS S30400) under ASTM standard, equivalent to 1.4301 in EN standard and SUS304 in JIS standard. Every link from raw material selection, hot-rolled processing to testing and packaging is strictly inspected in accordance with ASTM standard specifications, ensuring uniform thickness, stable performance, and compliance with international quality standards. Each batch of products is accompanied by a Mill Test Certificate (MTC) to provide authoritative proof of quality, which can directly meet the import requirements of markets that recognize ASTM standards such as the United States, Canada and Europe.

The core advantage of 304 stainless steel lies in its outstanding anti-corrosion performance, which is derived from its precise chemical composition—chromium content of 18.00-20.00% and nickel content of 8.00-12.00% form a dense and stable passive film on the surface, effectively resisting oxidation, rust and corrosion from general acidic and alkaline media, humid air and fresh water environments. Compared with ordinary carbon steel and low-grade stainless steel, it can maintain good structural integrity and surface quality for a long time in harsh environments such as outdoor humidity and industrial light corrosion, without frequent maintenance, greatly reducing the use cost. It should be noted that it is not suitable for strong corrosive environments such as high-concentration chloride ions, which can be matched with 316L grade products according to actual needs.

Adopting advanced hot-rolled processing technology, the product is rolled at a high temperature above 900°C (higher than the recrystallization temperature of stainless steel), which makes the internal structure of the steel more uniform, with low residual stress, excellent toughness and ductility. The hot-rolled plate has the characteristics of thick thickness range, strong load-bearing capacity and simple processing, and its production cost is lower than that of cold-rolled plates, which can effectively reduce the procurement cost of customers. The surface of the hot-rolled plate is slightly rough (usually with No.1 finish) and may have a thin oxide layer, which can be further processed by pickling, annealing or polishing according to application needs to meet different surface quality requirements.

The 304 hot-rolled stainless steel plate has excellent mechanical properties, with tensile strength ≥515MPa, yield strength ≥205MPa, and elongation ≥40%, which can withstand a certain pressure, impact and load, and is not easy to deform or break. It has good cold processing and welding performance, and can be flexibly cut, bent, punched, welded and drilled according to actual installation and production needs, without complicated heat treatment procedures after processing, which effectively reduces on-site construction and production costs, and improves work efficiency. It is suitable for both large-scale batch production and small-batch customized processing.

With its excellent anti-corrosion performance, stable mechanical properties and compliance with ASTM standards, our 304 hot-rolled stainless steel plate is widely used in various fields, covering industrial production, architectural decoration, daily life and other fields, and is a universal stainless steel material with high cost performance:

• Industrial Field: Chemical equipment, pressure vessels, heat exchangers, pipeline components, boiler accessories, food processing equipment, which can resist light corrosion of industrial media and ensure stable operation of equipment.
• Architectural Decoration: Building exterior walls, roof panels, curtain walls, handrails, stairs, door and window frames, decorative panels, etc. The hot-rolled plate with thick thickness is suitable for load-bearing parts, and the surface can be polished to meet the aesthetic needs of high-end decoration.
• Infrastructure: Water supply and drainage pipelines, sewage treatment equipment, bridge components, outdoor billboards, which can adapt to outdoor humid and harsh environments and have a long service life.
• Daily Use: Kitchen utensils, stainless steel tables, storage equipment, medical equipment accessories (non-strong corrosive scenarios), which meet the requirements of hygiene and corrosion resistance.
• Other Fields: Automobile parts, shipbuilding accessories, aerospace auxiliary parts, precision instrument brackets, etc., relying on stable performance to meet the needs of different industries.
