GENERAL PROPERTIES
- The 304/304L Stainless Steel Rod alloy is a superior version of the standard 304/304L, specifically treated to enhance machinability and ensure greater uniformity. This high-performance alloy allows for faster machining, prolonged tool life, superior part quality, and reduced overall machining costs. When annealed, the 304/304L Stainless Steel Rod is non-magnetic; however, it may exhibit slight magnetic properties post cold-working or welding.
- Specifications : UNS S30400, UNS S30403
APPLICATIONS:
DAUXN 304/304L Stainless Steel RODS are utilized in a broad spectrum of household and industrial applications, which include:
- Chemical process equipment
- Food and beverage industry
STANDARDS:
- ASTM/ASME: UNS S30400 / S30403
- EURONORM: 1.4301 / 1.4307
CORROSION RESISTANCE:
- The DAXUN 304/304L Stainless Steel Bar is an adaptable and highly versatile stainless steel, offering robust resistance to atmospheric corrosion as well as corrosion from a diverse array of organic and inorganic chemicals, including those found in food and beverages.
