304/304L Prodec Stainless (UNS S30400/S30403)

wilsonpipeline 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

• Resistance

 

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.
