- There are several varieties of steel. For example, there is mild steel, carbon steel, and low temp carbon steel. To clarify, carbon steel is further classified as low, medium, high, and ultra-high carbon steel, as well as low and alloyed steel. Yet, each of these begins with carbon as part of the composition.
- The content of carbon contained in these varieties of steel determines its use in manufacturing processes. Mild steel has low carbon content and carbon steel is considered a rough grade since it contains higher levels of carbon.
Low Carbon Steel
- Low carbon steel is composed of 0.04 – 0.30 % carbon. Welders and piping experts prefer low Carbon steel LF2 FLANGES for things like boiler plates, wire products, and seamless tubing and piping uses. Auto manufacturers typically prefer low-carbon steel for vehicle body panels. If the low-temperature carbon steel piping is seamless, it can be installed when processing or manufacturing piping requires low temperatures to avoid a negative impact on this type of piping. One example of the use of low-temperature carbon steel pipe would be in processes where refrigerants are required to be 50° F. If this is the case, choose ASTM A333 Grade 6 Low Temp Seamless Carbon Steel for transporting refrigerated process materials through a system. This is a simple guide to new installations of low carbon steel pipes with chemical components that include:
- . Carbon (max) 0.30
. Manganese at 0.29-1.06
. Phosphorus (max) 0.025
. Sulfur (max) 0.025
Carbon Steel
- Carbon steel relies heavily on the physical properties and structure of its grain. The content of carbon in carbon steel pipe is higher than that of low temp, mild, or other plain carbon steels. This particular type of steel is stronger, more durable, and used most often for a wide variety of projects. Note that carbon steel is classified, according to its carbon content in three categories:
. Low alloy
. High alloy
. Plain carbon - The percentage of alloy in carbon steel affects weldability, hardening process, and corrosion resistance. Installation of carbon steel pipe should consider these factors.
- The properties of low alloy steel pipes are chromium (Cr), molybdenum (Mo), and nickel (Ni). These alloys range from 2.07 percent to approximately 10.5 percent of total content.
- High alloy Carbon Steel-
- High alloy carbon steel has chromium properties of 2.07 percent and nickel alloy. As a type of stainless steel, it is preferred for various carbon steel pipe usages for industrial processes where corrosion resistance is a factor.
