Application of Urea Grade 00Cr17Ni14Mo2 (316L, UG) Steel

Introduction

00Cr17Ni14Mo2 steel, commonly known as UG (Unalloyed General) stainless steel in Europe and 316L in the United States, is a member of the low-carbon stainless steel family. This grade of steel has excellent corrosion resistance, particularly in environments containing chlorides, and is widely used in a variety of industries. 00Cr17Ni14Mo2 is often specified for design in applications where superior corrosion resistance and formability is necessary.

Chemical Composition

00Cr17Ni14Mo2 steel is composed of iron, chromium, nickel, molybdenum, manganese and the trace elements of sulfur and phosphorus. The relatively low content of carbon allows this stainless steel to be used in applications where higher carbon levels would standard grade austenitic stainless steels, such as 304. The additional molybdenum addition helps strengthen the steel and provides better oxidation resistance, while the nickel addition gives improved toughness when compared to 304 stainless steel.

Physical Properties

00Cr17Ni14Mo2 has ample strength and ductility, making it a superior choice for a wide range of industrial applications. The steel has a melting point of 1370-1400°C and a thermal conductivity of 25 watts per meter-Kelser. This grade of steel offers high yields, tensile and elongation values, and the ability to operate in a wide range of temperatures. It also offers superior formability, weldability and machinability when compared to other stainless steels.

Applications

00Cr17Ni14Mo2 is a versatile grade of steel and is suitable for use in a variety of applications, including:

Chemical Processing

Due to its superior corrosion resistance, 00Cr17Ni14Mo2 is commonly specified for applications that involve contact with strong acids and chlorides or temperatures at or near the boiling point of water. In these processing applications, it is often used in parts such as vessels, pumps and piping that are exposed to highly corrosive chemicals.

Food Processing

Food processing and beverage production also can benefit from the use of 00Cr17Ni14Mo2. Its superior formability and weldability make it an ideal choice for applications that require frequent cleaning and sterilization. It is often used in food processing equipment, pumps, blades and housings, as well as vessels and piping.

Architectural and Structural Design

00Cr17Ni14Mo2 is also ideal for architecture or structural design applications. Its excellent corrosion resistance, combined with a higher ductility and formability than other standard grades of austenitic stainless steel, allows it to be used in many structural components. The steel is often used in balcony railings, sculptures, wall panels, ornamental facades and structures, as well as stair railings, building facades and decorative trim.

Conclusion

00Cr17Ni14Mo2 steel offers a combination of formability, strength and corrosion resistance. This grade of steel is suitable for a wide range of applications, from chemical processing and food processing to architectural and structural design. It is widely used in industries due to its ability to perform in demanding environments, as well as its low maintenance requirements

00Cr17Ni14Mo2(316L, UG) steel is a kind of low carbon stainless steel developed to prevent intercrystalline corrosion of austenitic stainless steel and is generally applicable to equipment in contact with various corrosive media in chemical, petrochemical, fertilizer and other industrial sectors, as well as medical, food and other industries.

In general, its corrosion resistance is very strong and can withstand harsh corrosive medium in the production process. 00Cr17Ni14Mo2 stainless steel has good weldability and can be easily welded by ordinary welding materials after proper heat treatment. After welding and forming, it should be subjected to heat treatment again in order to make the steel better comply with certain requirements.

00Cr17Ni14Mo2 stainless steel has good processability and can be cold, hot rolled, forged, etc., as well as cold formed, cutting, bending and other processing. 00Cr17Ni14Mo2 steel has strong mechanical properties, higher strength, better corrosion resistance and good hot workability. Medium, steam and other corrosive media, as well as all kinds of mechanical parts and engineering components, which require better corrosion resistance and high strength, are often made of 00Cr17Ni14Mo2 stainless steel.

00Cr17Ni14Mo2 steel can also be used in various chemical equipment, such as containers, reaction devices, pipes and pipe fittings, tanks and vessels, pumps, valves and other components. In addition, it is also used in the production of various medical instruments, surgical instruments and medical devices, as well as food industry containers, devices and equipment. Due to its good corrosion resistance, 00Cr17Ni14Mo2 stainless steel can also be used in sea and offshore engineering without surface protection.
