904L stainless steel sheet including hot rolled stainless steel sheet, cold rolled stainless steel sheet and finish rolling stainless steel sheet.
Super austenitic stainless steel(904L stainless steel sheet) with very low carbon content and high alloy, it has well resistance to corrosion in dilute sulphuric acid, desinged specially for harsh environment corrosion conditions.It has enough Nickel and Chrome content, add Cuprum makes it antiacid ability,espencially has high resistance for chloride crevice corrosion and stress corrosion cracking,pitting spots and cracks are not easy to appeared,carry pitting capacity is better than other steels, with well machinability and weldbility,could be used for pressure vessel.

Form of Supply
Foshan LSDare supplier and stockholder of round bar, sheet and plate in 904L stainless steel.
Diameters can be supplied bandsaw cut to your requirements. Ground 904L stainless steel bar can be produced, providing a high quality precision ground stainless bar to your tight tolerances. Also available in plate which can be supplied as 904L plasma cut pieces.
Applications
904L is widely used in the chemical, pharmaceutical, oil and gas industries. Typical applications include tanks, valves, heat exchangers, flanges and manifolds.
The addition of copper to the composition of 904L aids its suitability for components such as tanks and other products used in handling sulphuric and phosphoric acid.
Corrosion Resistance
Where a level of resistance to pitting corrosion better than 316 is required 904L may be suitable. With its high nickel content at 25% it offers improved resistance to chloride stress corrosion cracking compared to other austenitic grades such as 304.
Welding
904L can be welded using common fusion and resistance methods. A more highly alloyed filler is recommended to give the optimum corrosion properties in the weld. We recommend you contact your welding consumables supplier who should provide you full assistance and information on welding 904L stainless steel.
