Introduction to ALLOY STEEL SA 387 GR. 11 CL. 1 / 2 plates

Alloy steel plates are used in variety of industries due to its improved properties. These plates have properties such as high strength, wear resistance, corrosion resistance, toughness and hardness. Alloy steel is alloys which can be easily machined and fabricated into plates for the use in industrial area. The alloy plates are manufactured by keeping some international standards in mind. These standards are important as they define the range of quality and properties that a material or finished product should have. ALLOY STEEL SA 387 GR. 11 CL. 1 / 2 plates are among the other plates which are widely used.

If we talk about the Standard Specification for Pressure Vessel Plates, Alloy Steel, Chromium-Molybdenum, here grade 11 alloy class 1 or 2 plates of standard 387 is used. Many more standards and specification will be discussed later in the article but before that let us understand the elements of the alloy.

Different elements used in ALLOY STEEL SA 387 GR. 11 CL. 1 / 2
The steel plates contain definite elements with some additional elements whose concentration depends upon the type of alloy. However, the common alloy include following elements:

  • » Aluminum
  • » Cobalt
  • » Columbium
  • » Nickel
  • » Tungsten
  • » Molybdenum
  • » Titanium
  • » Boron
  • » Vanadium
  • » Zirconium and chromium

Every plate differs in the composition of these elements and their manufacturing conditions also differ. These factors are kept in mind which gives them importance in different industries. The ALLOY STEEL SA 387 GR. 11 CL. 1 / 2 plates are used highly in oil and gas industries, petrochemical and other industries. At these areas, gas and liquids are stored at higher temperatures and thus extreme care is to be taken. These plates are designed in such a way that they can tolerate high temperatures.

Why ALLOY STEEL SA 387 GR. 11 CL. 1 / 2 plates?
The plates are annealed in different condition which offers them strength. Since these plates are to be worked at high temperatures and pressure environment therefore the elements included in it matters a lot. What elements are added in the manufacturing add different properties for example, high level of chromium adds excellent corrosion resistance. It also offers excellent oxidation resistance. Resistant to oxygen is important in petrochemical and gas industries and therefore these plates are used.

These alloy steel is called as pressure vessel grade that work at elevated temperature. This is possible due to the chrome molybdenum alloy. It also provides resistance to high temperature which is highly effective at higher temperatures.

Applications of ALLOY STEEL SA 387 GR. 11 CL. 1 / 2 plates
Plates of this grade alloy steel hold importance in following applications:

  • » Industrial boilers
  • » Heat exchangers
  • » Pipe work
  • » Pressurized vessels

As per requirement, the dimensions of these plates vary where its thickness can range from 5 to 150 mm. Width and length also varies according to the need of applications. However, many other grades of alloy steel are in used that includes grade 12, 9, 5, and 22.

All these grades vary in term of their properties, specifications, and dimension however they all comply with international standards.
