304/304L Prodec Stainless (UNS S30400/S30403)
Yaang Stainless inventory includes Prodec 304/304L (UNS S30400 / S30403) in stainless steel plate products.
General Properties
Prodec Alloy 304/304L is an improved version of standard 304/304L processed for improved machinability and outstanding uniformity. This alloy offers faster machining speeds, longer tool life, improved part quality and lower total cost of machined parts. Prodec 304/304L is nonmagnetic in the annealed condition, but may become slightly magnetic as a result of cold working or welding.
Specifications: UNS S30400, UNS S30403
Applications:
Prodec 304/304L Stainless Steel is used in a wide variety of home and commercial applications, including:
- Chemical process equipment
- Food and beverage industry
Standards:
- ASTM/ASME: UNS S30400/S30403
- EURONORM: 1.4301 / 1.4307
Corrosion Resistance:
- Prodec 304/304L is a versatile, general purpose stainless steel with good resistance to atmospheric corrosion, to many organic and inorganic chemicals, and to food and beverages.
- It has also been used in vacuum processing equipment and specialized instruments where high integrity is essential.
- Good oxidation resistance in intermittent service to 1600°F and in continuous service to 1690°F.
- Continuous use of 304 in the 800-1580°F range is not recommended if subsequent aqueous corrosion resistance is important.
