OEM Services of Stainless Steel Investment Casting in CFS Foundry

Stainless Steel is used for investment castings that require high resistance to corrosion and wear in safety-critical applications for defense, oil and gas, medical and other commercial industries. Stainless steel is a group of ferrous alloys that all contain chromium – the key ingredient for superior corrosion resistance. There are many grades of stainless steel with varying alloy composition and physical characteristics. All stainless steels contain at least 10.5 percent chromium but may contain significantly more depending on the application.…

17-4 PH vs 316 Stainless Steel Casting

17-4 PH vs 316 Stainless Steel Casting

SS316 and 17-4 PH are common used two types of stainless steel grades for investment casting. 316 is typical austenite stainless steel casting grade, while 17-4 PH stainless steel is precipitation hardening material grade, which are all defined in American standards. When you compare Stainless Steel 17-4 ph vs 316 for casting, it is obvious that 17-4 PH has the higher hardening content. Precipitation hardening grade is actually a combination of two stainless steel structures such as austenite and martensite.…

Stainless Steel Casting for Mixing Impeller

Stainless Steel Casting for Mixing Impeller

Impellers are the component of the mixer which imparts flow. Mixing impeller, also called agitator blades, is designed and manufactured to transfer the energy driven by the motor to the contents of a tank as quickly and efficiently as possible. There are mainly four types of mixing impellers, and each mixing impeller type converts the energy given to it in a different way: Airfoil: Generally most efficient because it produces the maximum pumping with the lowest shear. Pitch Blade: Ideal…
