Low Temperature Carbon Steel

Low-Temperature Carbon Steel Products typically contain iron, carbon, and trace amounts of other elements including manganese, molybdenum, and silicon. Depending on the intended application of the product, additional elements may be present to create an ingredient profile designed for increased strength or corrosion resistance.

Low-carbon, mild, or plain steel is a type of carbon steel. The carbon content in mild steel is approximately 0.5-0.25%. It is also one of the most commonly used steels because of its low price and properties that make it usable in many applications. The surface hardness of low-temperature carbon steel can be increased through carburizing. Low-carbon steel's tensile strength is low compared to other steel types. Cold-forming in low-carbon steels is more accessible due to the lesser carbon content in the steel.

Low-temperature carbon steel sometimes referred to as ASTM low-temperature carbon steel, is increasingly becoming the go-to alloy for several industrial and commercial applications. This versatile material exhibits a combination of strength and hardness even at lower temperatures which properties it has over other alloys. Its excellent weldability and formability allow the material to be easily manipulated in high-strength cryogenic storage vessels, piping systems inside superconducting laboratories, liquefied natural gas tanks, and thermowell. Due to their exceptional corrosion resistance, low-temperature carbon steels can also be found in numerous environments, including marine and dockyards. As a result of its versatility across different atmospheric conditions, astm low-temperature carbon steel has become one of the most popular materials used in the metals industry today.


Low-temperature carbon steel has various fascinating applications, making it a popular material in multiple industries. One of its most prominent uses is constructing cryogenic storage vessels storing fluids at shallow temperatures. This steel is also utilized in manufacturing pipelines that transport liquefied natural gas (LNG), as it retains its strength and durability even in sub-zero temperatures. In addition, low-temperature carbon steel is an ideal choice for fabricating marine structures and offshore oil rigs, where it can withstand harsh weather conditions and resist corrosion. With these qualities and many more, it's evident why low-temperature carbon steel is a versatile material preferred in various industries.
