SAE 904L: Chemical Composition, Propertes and Applications

SAE 904L is a non-stabilized austenitic stainless steel alloy that is known for its high corrosion resistance properties. It contains high levels of nickel and molybdenum, which give it excellent resistance to a wide range of corrosive environments. In this article, we will discuss the properties of SAE 904L stainless steel in detail. Equivalent grades include: EN 1.4539 (X1NiCrMoCuN25-20-5) UNS N08904 AISI 904L DIN 1.4539 ASTM A182 F904L JIS SUS 890L AFNOR Z2 NCDU 25-20 Chemical Composition:...

Composition, Properties, and Applications of A240 type TP410

ASTM A240/A240M is a standard specification for chromium and chromium-nickel stainless steel plate, sheet, and strip for pressure vessels and for general applications. The most commonly used grades are the austenitic grades such as 304, 304L, 316, and 316L, which have a high content of chromium and nickel and offer good corrosion resistance, high strength, and good formability. Other grades include ferritic and martensitic grades such as 409, 410, 430, and 440C, which offer good resistance to high-temperature...

How to improve the bonding force of electroless nickel plating on stainless steel

Electroless nickel plating of stainless steel parts (drive shafts, meshing parts, moving parts, etc.) can improve the uniformity and self-lubricity of the plating, which is better than chromium plating. However, electroless nickel plating on stainless steel often results in unsatisfactory bonding between the plating layer and the substrate due to poor pretreatment, which has become an urgent problem in actual production. The original process: mechanical polishing → organic solvent degreasing →chemical degreasing → hot water washing → electrochemical degreasing → hot water washing → cold water washing→ 0%HCl → cold water washing→ 20%HCl(50℃)...
