Material Properties: ASTM A403 WP304 / CR304 (UNS S30400)

ASTM A403 WP304 / CR304 refers to the standard Austenitic Stainless Steel 304, specifically designated as UNS S30400. This alloy is the most widely used stainless steel worldwide, renowned for its excellent combination of corrosion resistance, fabricability, and cost-effectiveness. Its composition, primarily iron with significant chromium and nickel additions, makes it versatile for numerous applications where a good level of corrosion resistance is required but extreme conditions (like those requiring duplex or high-nickel alloys) are not present. It is also known by its European designation 1.4301.

DIPTI METAL INDUSTRIES, as a leading UNS S30400 Butt-Weld Fittings supplier, ensures all materials meet stringent international standards and offer full material traceability. We also supply other stainless steel grades like WP304L and WP310S.

Key Characteristics of WP304 / CR304 (UNS S30400):

• Composition: A chromium-nickel austenitic stainless steel with good corrosion and heat resistance. Key elements include Chromium (18-20%) and Nickel (8-10.5%).
• Good General Corrosion Resistance: Provides effective resistance to a wide range of corrosive media, including fresh water, non-oxidizing acids, alkaline solutions, and atmospheric conditions. It performs well in many chemical processing, food, and dairy environments.
• Excellent Formability: High ductility allows it to be easily drawn, stretched, or spun into complex shapes, making it ideal for various fabrication methods.
• Superior Weldability: Can be welded using all standard fusion methods with or without filler metals. For heavy sections, the low carbon variant (WP304L) is preferred to avoid carbide precipitation and intergranular corrosion.
• Non-Magnetic: In the annealed condition, it is typically non-magnetic, but can become slightly magnetic after cold working.
• Good Mechanical Properties: Offers a useful balance of strength, ductility, and toughness at both ambient and cryogenic temperatures.
• International Equivalents: Widely known as SS 304, and its European equivalent is 1.4301. Also referenced in many national standards like JIS (SUS304).

Note: Detailed chemical analysis and specific mechanical properties for each batch and grade are provided in the EN 10204 3.1 Mill Test Certificate (MTC). Our expertise as a top WP304 Butt-Weld Fittings manufacturer in Mumbai ensures meticulous control over material properties, including those comparable to 1.4307.
