Significance of Using Seamless Rolled Rings

Seamless rolled rings are shaped and bent through the process of ring rolling by using quality and efficient rolling mills. A circular preform of metal is perforated using the open die forging method to create a hollow shape that looks like a donut. Before placing the donut over the idler roll or the mandrel roll, the shaped metal is heated above the recrystallization temperature. With this, you’re guaranteed that finished products are only of the highest quality. Continue reading to know the significance of using seamless rolled rings.

Are Seamless Rolled Rings Worth the Investment?

Types

Before anything else, it is best that you should know the various types of seamless rolled rings. Primarily, it is divided into 3 – stainless, alloy, and carbon rolled rings. Stainless rolled rings are quality steels that can withstand heat and corrosion. It contains a few alloy elements and about a minimum of 10% Chromium. Likewise, it is commonly used in chemical and food processing applications.

Alloy seamless rolled rings are also made of steel but contain a bigger quantity of alloy elements. Alloying elements provide steel with fatigue resistance and improved strength. Hence, the combination of these materials makes the finished product worth the investment.

As for carbon rolled rings, it contains steel and carbon. However, it is often combined with other elements that are small. Carbon seamless rolled rings are used for pressure vessel and structural applications.

Advantages

Rolled and welded plates, as well as, casting methods are both metalworking processes that allow manufacturers to create rolled rings. Cast rings are known to be subject to inclusion defects that require additional machining, as well as, weld repair. Once the fabricated ring goes through a complicated welding process, the integrity of its part is reduced. Aside from its integrity, the shape becomes distorted and its corrosion resistance is also jeopardized.

On the other hand, with the seamless rolled rings process, the directional grain flow will result in an increase of the forging’s overall strength. More so, the maintenance of the part’s corrosion resistance and shape is guaranteed since there is an absence of welding.

Understanding Carbon Steel Rolled Rings

Creating carbon steel rolled rings is a process that uses carbon steel. It contains up to around 1.2% carbon while other present elements are in quantities too small to impact its properties. With this material, carbon rolled rings are commonly used for pressure and structural vessel applications. To understand more about carbon steel rolled rings, below are the facts you need to know.

All About Carbon Steel Rolled Rings

Why Choose Carbon Steel

Manufacturers engaged in rolled ring production will tell you that carbon steel is among the most cost-effective option when it comes to steel. Since it is cost-effective, the rolled rings process can attain the high strength a stainless steel can offer. However, you can still achieve good quality products that can be hardened through tampering and quenching.

Carbon Steel Grades

High-grade carbon steel rolled rings is often used in applications that don’t require high temperature or high strength environments. Below are the carbon steel grades you need to familiarize yourself with.

  • A Grade – This type of carbon steel is ideal for oil field applications since it is corrosion resistant. It comprises alloy substance such as nickel or manganese. Thus, it can enhance the toughness and hardenability of the metal produced.
  • High Carbon Steel – Akin to A Grade carbon steel, this type also comprises manganese to improve hardenability and toughness. It can be heat treated or welded for higher durability.
  • Low Carbon Steel – This is commonly known as re-sulfurized carbon steel as it contains sulfur to provide exceptional machinability.
  • Plain Carbon Steel – The least expensive type but provide a good welding factor. It comprises high carbon content and low alloy content. Hence, plain carbon steel can offer excellent surface hardness and good toughness.

Capabilities of Carbon Rolled Ring

Carbon rolled rings utilize a foolproof forging process that creates seamless rolled rings with outstanding circumferential grain flow and ample internal structure. Also, the precision rolling procedure offers exceptional surface smoothness and concentricity.

Closed Die Forging | The Closed Die Forging Process

Forging is a manufacturing process involving the shaping of metal using localized compressive forces. When it comes to forging, there are two types: closed die and open die. In this blog, we will take a look at closed die forging and the process that goes into it.

Creating the Mold

The first step of the closed die forging process involves creating the mold. The mold allows for the forgings to be created to the exact specifications of the customer. The creating of the mold and the subsequent creating of the forging can take 2-3 weeks to complete.

Choosing the Steel

Depending on the type of forging and its use, there are several different types of steel that can be used in the closed die forging process. Stainless steel, carbon steel, and alloy steel are all common types of steel found in forgings. Stainless steel is used where both the properties of steel and corrosion resistance are required and is typically the most popular steel option.

Heating the Steel

Before the steel can be forged, it has to be heated. When the steel is heated to the desired temperature, it can be molded and formed into a new, desired shape. Once it is heated to the desired temperature, it can be placed in the mold to form the desired shape.

Forging the Steel

After the mold has been created and heated, the forging process can then begin. After the mold has been created, it is then placed within the closed-die forging dies.

Stainless Steel Castings | Common Alloying Elements

If you need stainless steel castings, there are numerous of different metalworking methods that can be done to make your part as specific as possible. One of these specific metallurgical processes is adding alloying elements. Alloying elements can change the structure, corrosion resistance, and mechanical properties of stainless steel castings. Furthermore, every different alloying element effects stainless steel differently. Below we explained the effects of 5 common alloying elements used for stainless steel castings so that you can determine which is best for your next project.

Effects of Alloying Elements on Stainless Steel Castings

1. Manganese: Adding manganese to stainless steel improves hot working properties and boosts toughness, strength, and hardness.

2. Nickel: Nickel can help produce stainless steel castings that are incredibly ductile, corrosion resistant, and tough at both high and low temperatures.

3. Chromium: Stainless steel parts with higher percentages of chromium have a higher resistance to oxidation than parts with lower percentages of this alloying element.

4. Carbon: Carbon, along with iron, is the major alloying element that is used to make stainless steel. It is also used to increase the hardness and strength of the metal.

5. Copper: This alloying element enhances the corrosion resistance and formability of the stainless steel castings. Copper can also be added to decrease work hardening in grades designed for improved machinability.

It’s safe to say that alloying elements can have major effects on stainless steel castings. Now that you know the effects that common alloying elements have on stainless steel, it’s time to determine the best option for your specific needs.
