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.

SpecificationsUNS S30400, UNS S30403

Applications:

Prodec 304/304L Stainless Steel is used in a wide variety of home and commercial applications, including:

  1. Chemical process equipment

  2. Food and beverage industry

Standards:

  1. ASTM/ASME:  UNS S30400/S30403

  2. EURONORM: 1.4301 / 1.4307


Corrosion Resistance:

  1. 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.

  2. It has also been used in vacuum processing equipment and specialized instruments where high integrity is essential.

Heat Resistance:

  1. Good oxidation resistance in intermittent service to 1600°F and in continuous service to 1690°F.

  2. Continuous use of 304 in the 800-1580°F range is not recommended if subsequent aqueous corrosion resistance is important.

Properties of 304 Alloy

Welding Characteristics:

  1. readily welded by full range of conventional welding procedures except oxyacetylene.

  2. AWS E308L/ ER308L filler metal should be used with Prodec 304/304L steel.


Machinability:

  1. offers faster machining speeds, longer tool life, improved part quality and lower total cost of machined parts.
