CF3M stainless steel is the equivalent type of 316L stainless steel, which is specially used in investment casting process. It is the low-carbon modification of CF8M. The presence of molybdenum increases the general corrosion resistance and the resistance to pitting by chlorides. CF3M has similar corrosion resistance and mechanical properties to CF8M. The difference is that the tensile yield strength of CF3M is somewhat less than that of CF8M at ambient temperatures. CF3M alloy is limited to a maximum temperature…

Stainless steel and aluminum are the common material for casting. Although stainless steel castings and aluminum castings are similar in appearance, they each have distinct characteristics that make them unique. Before beginning your next project, it is necessary to consider the main differences between stainless steel casting and aluminum casting: Casting Process The casting processes to form stainless steel castings and aluminum castings are not the same. Generally, stainless steel castings are formed by investment casting process, while aluminum castings…

CF3 Stainless steel is the equivalent type of 304L stainless steel, which is specially used in investment casting process. CF8 and CF3 have very similar chemical and mechanical properties. CF3 is a variation of CF8 and has a lower carbon content which improves weldability and lowers the risk of reduced corrosion resistance around the weld. CF3 is preferred to CF8 when there will be no post-weld heat treatment. Solution annealing is necessary for maximum corrosion resistance and to prevent intergranular attack.…

CF8, ASTM 351 standard, is the common cast alloy used in stainless steel investment casting process. Maybe you will ask what CF8 means? C –  The first letter means corrosion resistant feature that is intended to be used for casting, but CFS stainless steel foundry think it may also mean casting purpose, as you can also find F304 in ASTM A350 standard, here F means Forging. F – The second letter indicates the approximate location of the alloy on the…

What is PVD Coating? PVD, short for Physical Vapor Deposition, refers to a thin film coating technique in which material is deposited on the stainless steel castings after mirror polishing by physical means under vacuum conditions. PVD coating technology for polished stainless steel casting is mainly divided into decorative coating and tool coating. 1. The purpose of PVD decorative coating is mainly to improve the surface decorative performance and color of polished stainless steel castings, while making stainless steel castings…

Precision Casting Basics Precision Casting, as its name implies, is the casting process for precision parts. This type of casting method is actually a lost wax investment casting process, which will be able to produce net or near net shape, high-dimensional accuracy and intricate design. In precison casting process, the first step is to build a wax version of the final product, whose dimensions are the same as finished castings. This can be done in 3 steps:  Design and manufacturing…

If you are familar with stainless steel investment casting, you may know the traditional stainless steel investment casting process contains these steps: process design, molding manufacturing, wax patterns manufacturing, wax patterns assembly, shell making, dewaxing and roasting, pouring, shell removing and post-processing. While, by using 3D printing, it can replace the procedures of molding and wax patterns manufacturing, which can improve production efficiency and save the molding cost for customers. Stainless Steel Casting Process by 3D Printing Process Design Designing…

When talking about the way to color stainless steel castings, titanium vacuum plating is recommended to our customers. Vacuum titanium plating is an ideal surface color coating technique for stainless steel casting, which is operated under the condition of vacuum. With the arc discharge, cathode titanium target was used as the evaporation source, through the arc discharge between the titanium target and the anode, the titanium target is evaporated to form ion. The generated ions are moving onto the surface…

About Solenoid Valve Solenoid valves are the most frequently used control elements in fluidics. Their tasks are to shut off, release, dose, distribute or mix fluids. They are found in many application areas. Solenoids offer fast and safe switching, high reliability, long service life, good medium compatibility of the materials used, low control power and compact design. Generally, a complete solenoid valve consists of several components, including: valve body/housing, valve cover, coils, diaphram, plunger, fixing nuts, etc. Among them, some…
