Carbon is considered to be one of the most important commercial steel alloys. Carbon helps in increasing the strength and hardness of steel. Adding more carbon leads to improve hardness and resistance of the steel. However, carbon also increases the brittleness of the steel. If the amount of carbon is too high in steel, then it reduces the weldability. Being keen about carbon content in the steel is essential. It is considered as both blessing and curse for the commercial steel. Whether its alloy steel base rolls manufacturers or ring rolls manufacturers, the quality of their products rely on the carbon content in the steel.
Steels that have up to 2 percent of carbon content are rare as most of the steels available in the market contain less than 0.35 percent of carbon. Steel that includes 0.35 to 1.86 carbon can be hardened by applying heat-quench-temper cycle.
Usually, there are three types of commercial steel available in the market:
- Steel with plain carbon
- Steel with low-alloy
- Steel with high-alloy
Plain Carbon Steels
This steel can be considered iron which has less than 1 percent of carbon content. Along with that, it contains small amounts of manganese, silicon, sulfur, and phosphorus. This plain carbon steels can be divided into four types, low, medium, high, very high.
Low carbon steel contains less than 0.30 percent of carbon while medium carbon steel has 0.30 to 0.45 percent carbon. High carbon steel contains 0.45 to 0.75 percent of carbon. It is quite challenging to weld this type of steel. Steel that contains a very high percentage of carbon, which can be up to 1.50 percent requires heating treatment before during and after welding to keep their mechanical properties intact.
These steels are mainly created for welded applications. They contain less than 0.25 percent of carbon and often it is below 0.15 percent. Usually, alloy includes chromium, silicon, nickel, molybdenum, and manganese. They work for increasing the strength of the steel at room temperature. The perfect combination of these alloys provides corrosion resistance. However, the addition of the alloy might increases the risk of cracking. The low-hydrogen welding process would be ideal for them.
We can consider it as stainless steel. This is one of the most popular commercial high-alloy steel. It contains a minimum 12 percent chromium and many sheets of steel also contain nickel. The three basic types of steel are Austenitic, Martensitic, and Ferritic.
How to find reliable alloy steel base rolls manufacturers:
It is always better to deal with a manufacturer who has been in the industry for years. An experienced company knows how to take care of their customers, and they cater to their requirement without any error. You can ask quotations from a number of such companies and see which one offers the best deal. You can also consider online reviews and ratings given by previous customers. This can be helpful for catering your requirement of alloy rolls in India. Along with that, you can also check out other products offered by the company.
Carbon plays a crucial role in giving strength and hardness to the steel. Now we know the main types of steel alloys. These rolls are used in various applications. It is essential to find an experienced manufacturer can deliver your order on time.
