GENERAL PROPERTIES
- The 304/304L Stainless Steel Rod alloy is a premium enhancement of the standard 304/304L, meticulously processed to achieve superior machinability and consistency. This refined alloy ensures accelerated machining, prolonged tool longevity, enhanced part precision, and reduced overall machining costs. Initially non-magnetic post-annealing, the 304/304L Stainless Steel Rod may exhibit slight magnetism following cold working or welding.
- Specifications : UNS S30400, UNS S30403
APPLICATIONS:
The DAUXN 304/304L Stainless Steel RODS are integral to a diverse array of domestic and commercial applications, including:
- 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 a highly adaptable general-purpose stainless steel, offering robust resistance against atmospheric corrosion, a broad spectrum of organic and inorganic chemical corrosion, and resistance to food and beverage-induced corrosion.
- It is also essential in vacuum processing equipment and specialized instruments where maintaining high integrity is paramount.
HEAT RESISTANCE:
- Exhibits admirable oxidation resistance during intermittent use up to 1600°F and continuous use up to 1690°F.
However, the continuous operation of the 304 round bar within the 800-1580°F range is inadvisable if subsequent aqueous corrosion resistance is a priority.
WELDING CHARACTERISTICS:
- Readily welded by the full spectrum of conventional welding techniques, with the exception of oxyacetylene.
- For optimal results, AWS E308L/ER308L filler metal should be employed with Prodec 304/304L steel.
MACHINABILITY:
- Enables accelerated machining speeds, extended tool life, superior part quality, and a reduction in the overall cost of machined components.
VALUE-ADDED SERVICES
- To precisely meet your stainless steel rod requirements, Daxun offers the following value-added services:
HEAT TREATING & ANNEALING
- Daxun Stainless Steel Products provides heat treating services for select 400 Series Stainless Steel Bars. Heat treating induces specific stresses through hardening, contingent on the metal's composition. This process is also pivotal for tempering, quenching, normalizing, and solution annealing.
POSITIVE MATERIAL IDENTIFICATION (PMI)
- In certain scenarios, additional positive material identification testing may be essential. Daxun Stainless Products can administer this testing internally, or collaborate with an independent laboratory to fulfill these requirements. Please reach out for your specific needs.
UT TESTING
- Ultrasonic Testing (UT) employs high-frequency sound energy to perform detailed examinations and measurements of stainless steel products, facilitating flaw detection/evaluation, and dimensional assessments, among other analyses.
