904L Stainless Steel Sheet
What is 904L Stainless Steel Sheet?
Grade 904L stainless steel sheet represents a premium non-stabilized austenitic stainless steel with a low carbon composition. Enhanced with copper, this high-alloy variant stands out for its superior resistance to strong reducing acids, like sulfuric acid, and its robustness against stress corrosion cracking and crevice corrosion. It is distinguished by its non-magnetic nature and excels in formability, toughness, and weldability, catering to a wide range of applications.
Despite its high content of costly elements such as molybdenum and nickel, the versatile nature of 904L has seen it utilized in areas traditionally served by the more economical duplex stainless steel 2205. However, its unique properties continue to make it a sought-after material for specific demanding environments.
As a leading mill, Aoxing is well-equipped to meet the diverse needs of our clients, boasting an extensive inventory of 904L stainless steel sheets. With sizes ranging up to 1500x6000mm and thicknesses from 0.30mm to 12mm, our capacity to supply both standard and custom-sized plates ensures we can swiftly cater to unique project requirements. Our stock and the capability to produce even un-standard sizes swiftly underscore our commitment.
Features of 904L Stainless Steel Sheet
The 904L stainless steel sheet, also known as SS 904L, is acclaimed for its remarkable features, primarily due to its low carbon content, which effectively prevents carbide precipitation during heat treatment and welding. This characteristic significantly reduces the risk of intergranular corrosion, a common issue in other grades post heat treatment and welding processes. The SS 904L's superior corrosion resistance is attributed to its high levels of chromium, nickel, molybdenum, and the addition of copper, enabling passivation even in reducing environments, such as various concentrations of sulfuric and formic acid.
This grade's high nickel content ensures a reduced corrosion rate, particularly notable in sulfuric acid environments, where the 904L stainless steel plate can operate at temperatures up to 40 degrees Celsius. Its exceptional corrosion resistance extends to phosphoric acid across a wide range of concentrations, showcasing superiority over conventional stainless steels, especially in industrial applications with potential impurities.
However, in highly oxidizing conditions like nitric acid, the 904L shows somewhat less resistance compared to steel grades with higher alloying without molybdenum. Its application in hydrochloric acid is advisable only within a concentration range of 1-2%, within which it outperforms traditional stainless steels in corrosion resistance. Furthermore, alloy 904L exhibits a high resistance to pitting and maintains good crevice corrosion resistance in chloride solutions, thanks to its high nickel content which minimizes corrosion rates in vulnerable areas.
Distinguished from common austenitic stainless steels, 904L stainless steel plate showcases high resistance to stress corrosion cracking in environments rich in chloride, concentrated hydroxide solutions, and hydrogen sulfide, attributable to its enhanced nickel content. This blend of features makes SS 904L a premium choice for applications demanding both high corrosion resistance and durability.
