概要: Discover the ASTM B 677 NO8904 / 904L Stainless Steel Seamless Tube, a high-performance solution for demanding industrial applications. This video highlights its exceptional resistance to corrosive environments, superior weldability, and versatile applications in chemical processing, oil refining, and more.
関連製品特性:
  • Non-stabilized low carbon high alloy austenitic stainless steel with excellent corrosion resistance.
  • Enhanced resistance to strong reducing acids, particularly sulphuric acid, due to copper addition.
  • Highly resistant to chloride attack, including pitting, crevice corrosion, and stress corrosion cracking.
  • Non-magnetic in all conditions with excellent weldability and formability.
  • Suitable for cryogenic temperatures with excellent toughness.
  • Available in seamless sizes from 1/2" NB to 8" NB and ERW sizes up to 24" NB.
  • Complies with ASTM B677, B366, ASME SB677, and SB366 standards.
  • Ideal for applications in chemical, pharmaceutical, and paper industries.
よくある質問:
  • What makes 904L stainless steel tubes suitable for corrosive environments?
    904L stainless steel tubes are highly resistant to corrosive environments due to their high alloy content, including copper, which enhances resistance to sulphuric acid and other reducing acids. Their austenitic structure also provides excellent resistance to chloride-induced corrosion.
  • Can 904L stainless steel tubes be welded easily?
    Yes, 904L stainless steel tubes have excellent weldability and can be welded using standard methods. However, care should be taken as the grade solidifies fully austenitic, making it susceptible to hot cracking in constrained weldments. No pre-heat is required, and post-weld heat treatment is generally unnecessary.
  • What are the typical applications of 904L stainless steel tubes?
    Typical applications include processing plants for sulphuric, phosphoric, and acetic acids, pulp and paper processing, seawater cooling equipment, oil refinery components, and gas scrubbing plants. Their high corrosion resistance makes them ideal for harsh industrial environments.
