400 Series Steel Investment Casting

400 Series Steel Overview

400 series steel investment casting uses stainless steel alloys from the ferritic and martensitic groups. These stainless steels have chromium as their main ingredient, usually between 11% and 14%. The 400 series is special because it is magnetic, strong, and can be heat treated. Using 400 series alloys in stainless steel investment casting makes parts that are tough, last a long time, and fit together well. Many manufacturers pick these alloys when they need parts that resist wear and some corrosion. Stainless steel casting lets companies make parts with tricky shapes and smooth surfaces. This is why many industries use this process.

Key Properties of 400 Series Steel

400 series steel investment casting gives parts important mechanical properties. These stainless steel alloys are magnetic and can get harder and stronger with heat treatment. Martensitic grades like CA15 and 410 are very strong and resist wearing out. Ferritic grades such as 430 are also magnetic and fight off rust. Stainless steel investment casting with 400 series alloys makes parts that are easy to machine and work well in tough jobs. These alloys are good for making gears, shafts, bushings, valves, and pump parts. The investment casting process makes sure parts are very exact and have smooth surfaces, so less extra work is needed.

Tip: 400 series stainless steel casting is picked for its mix of strength, hardness, and some corrosion resistance. This makes it a top choice for machines and car parts.

Common 400 Series Alloys in Investment Castings

Manufacturers use many 400 series alloys in stainless steel investment casting. Martensitic stainless steels like 410, 416, and 440C are strong, magnetic, and can be heat treated. These alloys are used for knives, turbine blades, and valve parts. Ferritic stainless steels like 409 and 430 resist rust and are used in car exhausts and home appliances. The table below lists some common 400 series alloys and what they are used for:

Alloy(s)Key CharacteristicsPrimary Industrial Uses
410, 416Martensitic, high strength, good machinability, heat-treatable, magnetic, less corrosion resistantAutomotive parts, food & dairy industries, machine tools, knives, housings, bushings, handles, brackets
418, 420C, 430, 436, 440A, 440CMartensitic, can be quenched and tempered for hardness, magnetic, wear resistantValves, pump shafts, aerospace components, industrial tools, cutlery, blades, turbine blades, fasteners

Stainless steel investment casting with these alloys gives great corrosion resistance, strength, and long life. This makes 400 series steel investment casting a smart pick for industries that need exact and tough parts.

Stainless Steel Investment Casting Process

Lost Wax Method Overview

The stainless steel investment casting process starts with the lost wax method. First, workers design the part and make a mold from drawings. They fill the mold with wax to make a wax copy of the part. After the wax cools, they take it out and check for problems. Many wax models are put together on a wax tree. This lets them make many parts at once. The wax tree gets dipped in a ceramic liquid and covered with sand. They repeat this step to make the shell strong. When the shell is dry, it goes in an oven. The heat melts the wax and leaves a hollow shell. Hot stainless steel is poured into the shell. When it cools, workers break the shell to get the part out. They cut and smooth the parts as needed. This process makes parts with tricky shapes and smooth surfaces. It works well for 400 series stainless steel.

Quality Control in Stainless Steel Casting

Quality control is very important in stainless steel investment casting. Inspectors check the mold to make sure it is correct. They look at the wax model for cracks or mistakes. Workers watch the temperature and pressure when making the wax model. This helps stop holes from forming. The ceramic shell gets even coats and enough time to dry. This makes it strong. When melting and pouring, workers keep the heat steady and lower impurities. After casting, they use special machines to check the size. They use X-rays and sound waves to find hidden problems. Tests check the strength and makeup of the stainless steel. These steps make sure each part is strong and works well.

400 Series vs Other Stainless Steels

400 Series vs 300 Series

The 400 series and 300 series stainless steels are different. The 400 series has ferritic and martensitic types. These grades have more carbon and chromium. Many 400 series grades are magnetic. They can be heat treated to get stronger. They are good at resisting wear and usually cost less than 300 series. The 300 series is austenitic and not magnetic. These grades have more nickel. This makes them better at fighting rust and staying tough. They are easier to shape and cut. Many companies use 300 series stainless steel for food, medical, and chemical tools because it stays clean and does not rust.

  • 400 Series Stainless Steels:
    • Ferritic and martensitic types
    • More carbon and chromium
    • Magnetic
    • Can be heat treated for strength
    • Not as good at fighting rust
    • Costs less
  • 300 Series Stainless Steels:
    • Austenitic, not magnetic
    • Lots of nickel
    • Great at fighting rust
    • Easier to shape and cut
    • Used in tough or clean places

400 series stainless steel is best for strong parts that need to last. 300 series is better for parts that must fight rust and chemicals.

Consider When Selecting 400 Series Versus Other Stainless Steels

Picking the right stainless steel depends on many things. The place where the part will be used is very important. If a part needs to be strong or handle stress, the 400 series is a good pick. These grades can be heat treated and are magnetic, which helps for some jobs. If the part will touch strong chemicals or saltwater, the 300 series is better at fighting rust. Welding is different, too. The 300 series is easy to weld. The 400 series can be harder to weld. Cost matters as well. The 400 series is usually cheaper but may need more care in tough places.
