Leading Stainless Steel Sheet Suppliers in China

Standards and Specifications：

• Alloy 904L stainless steel plate is governed by a range of standards and specifications that ensure its quality and performance. Key standards include ASTM A240 and ASME SA240, which define the requirements for the chemical composition, mechanical properties, and dimensions of the material. Additionally, 904L stainless steel plate meets the criteria set by EN 10095, ISO 6208, and DIN 17750, among others. These standards guarantee that the material adheres to stringent quality controls, making it suitable for a variety of demanding applications. By complying with these standards, 904L stainless steel plate ensures reliability and consistency in performance across different industries.

Grade 904L Stainless Steel：

• Austenitic stainless steel of grade 904L is a non-stabilized, high alloy, low carbon steel. This grade is now significantly more resistant to strong reducing acids, especially sulfuric acid, because to the inclusion of copper.Copper is added to certain grades of stainless steel. This addition develops resistance to sulphuric acid and other reducing agents. The copper-containing grades perform better in both aggressive and mild conditions. They offer enhanced durability and long-lasting performance. Daxun Alloy carefully selects these grades for specific applications. Customers can trust these materials to withstand challenging environments.
• This grade has outstanding formability and weldability and is non-magnetic under all circumstances. This grade has exceptional toughness, even at cryogenic temperatures, thanks to its austenitic structure. This steel grade is known for its superior performance in harsh conditions.
• Nickel and molybdenum, two very expensive elements, are present in quite large amounts in 904L. Duplex stainless steel 2205 (S31803 or S32205) can now be used in many of the applications where this grade has historically performed well at a cheaper cost, hence 904L is used less frequently than it was in the past.

Corrosion Resistance：

• Its excellent resilience to a variety of conditions is in addition to its original development’s resistance to sulfuric acid. Warm seawater and other high chloride conditions are well-resistance for the material, as shown by a PRE of 35. Compared to the typical austenitic grades, high nickel concentration produces a significantly superior resistance to stress corrosion cracking. Sulfuric and other reducing acids are more resistant to copper, especially in the extremely aggressive “mid concentration” range.
• The corrosion performance of 904L is generally intermediate between that of the ordinary austenitic grade 316L and the highly alloyed “super austenitic” grades with 6% molybdenum and equivalent content.
• Compared to grades like 304L and 310L that are free of molybdenum, 904L is less resistant to strong nitric acid.
• After cold work, the steel should be solution treated for optimal stress corrosion cracking resistance in demanding situations.

Heat Resistance：

• Strong oxidation resistance, but at higher temperatures suffers from structural instability (precipitation of brittle phases like sigma), just like other highly alloyed grades. It is not recommended to use it above 550°C. The ASME Boiler and Pressure Vessel Code sets the design stress values for 904L at 371°C.

Heat Treatment：

• Solution Treatment (Annealing)Heat to 1090-1175°C and cool rapidly. This grade cannot be hardened by thermal treatment

Welding：

• It is possible to successfully weld 904L using all common techniques. Due of its totally austenitic solidification, this grade is prone to heat cracking, especially in restricted weldments, hence caution must be used.It is best not to employ any pre-heat, and post-weld heat treatment is typically not necessary either.Grade 904L rods and electrodes are prequalified by AS 1554.6 for 904L welding.

Fabrication：

• Because it is a high purity, low sulphur grade, 904L will not machine as well as other grades that have been specially designed for machinability. It is possible to machine grade 904L using conventional methods, nevertheless.Achieving a tiny radius of bend is easy. For the most part, this is done cold. Although it should be taken into consideration if the fabrication is to be utilised in a locati0n where severe stress corrosion cracking conditions are anticipated, subsequent annealing is typically not necessary.

Typical Applications：

• Processing plant for sulphuric, phosphoric and acetic acids. Pulp and paper processing.Components in gas scrubbing plants. Seawater cooling equipment. Oil refinery components. Wires in electrostatic precipitators.

Specified Properties：

• According to ASTM A240M, these characteristics are required for flat rolled products (plates, sheets, and coils). Other goods like pipe, tube, and bar have similar, though not always the same, qualities listed in their individual specifications.

904L Grade Stainless Steel Sheets in a Variety of Finishes

Daxun Alloy offers a variety of stainless steel sheets. These sheets come in a range of beautiful finishes. Customers can choose from brushed, 2B smooth, or 8K mirror finishes. Each sheet has a protective film on the finished side. This film is easily peeled off after fabrication or installation. It protects the surface from wear and marks. The back side of the sheet is unfinished.

904L Grade Stainless Steel Sheet is the most commonly used variety. It is easily weldable, formable, and has good corrosion resistance.
