Washers are small components that distribute the load of threaded fasteners like a bolt and nut. It can also be used as a spacer, spring and locking device. Additionally, it prevents the loosening of the fastening device because of vibrations from other machines. Without a doubt, it can greatly help in many industrial applications.
Washers have three types – plain, spring, and locking. It also comes in different sizes, diameter, and materials. When it comes to the size and diameter, you just need to follow the specifications. However, when it comes to the materials, you need to decide whether to consider 1008 Steel Washer Supplier or 1010 steel washers. These steel washers are made of carbon steel.
Carbon steel is common in many industries because it is affordable at the same time it provides exceptional mechanical properties. Carbon steel is made of 0.05% to 2.0% of carbon together with trace amounts of other elements. Here are some things to consider when deciding the carbon steel grade appropriate for your needs:
If it needs to be machined
You have to know that there are many kinds of carbon steel that can be machined easily. However, there are others that are difficult to machine. Grades with lower carbon steel like 1010 and 1018 are popular because of its good machinability.
Similarly, carbon steel with higher amounts like 1141 and 1144 can be considered because of its good machinability. These carbon grades have sulfur that helps them easily machined. 1045, on the other hand, have higher carbon amount but no additional elements. This makes it a bad choice if machining is needed.
Determining the strength requirements
Keep in mind that low carbon steel lacks tensile strengths compared to other carbon steels. If the application needs high strengths, low carbon steel should be avoided. With this, it is better to choose carbon steel with higher carbon content like 1045 as it can provide more hardness and strength. However, you should remember that low carbon alternative is designed having higher strengths while keeping its formability.
Choosing good corrosion resistance
Carbon steels are not famous for its ability to resist corrosion. Carbon steel is mostly made of iron, which can oxidise and form rust. Without the right corrosion-resistant elements added, nothing will keep it from oxidising. You should consider a galvanised or plated carbon steel if you want to prevent rusting.
Alternatively, you can also consider bluing, which is a technique that will immerse the steel into a water, potassium and sodium hydroxide solution. The most cost-effective way to protect parts against rust is through organic painting. Paints will make a barrier that can keep the corrosive elements against the carbon steel part. It effectively prevents the penetration of oxygen and water.
Knowing the applications
To help you choose the right grade for your project, you should know the common applications of different grades. Grades 1008, 1010 and 1018 are used in machinery parts, mounting, brackets and tie rods. Grades 1141 and 1144 are used in pins, studs, shafts, and bolts. Grade 1045 can be used in gears, bolts, shafts, die forges and many applications where more strength and hardness are required.
