Alloy Steel Plate

 

 

Any steel plate, where the content of alloying material ranges between 1% to 50%, is referred to as alloy steel. Further, AS is classified into two groups i.e. High Alloy Steel plate and low alloy plate, depending on the content of alloying material used in them. While the corrosion resistance of alloy steel is much higher than regular carbon steel, the mechanical properties tend to be much higher as well. For instance, the tensile strength of 4130 Alloy Steel coil is approx 655 MPa. In order to use low alloy grade, for instance, 4140 Alloy Steel strips, a proper heat treatment conducted on them prevents the steel from going through ductile to brittle phase. Thus enabling them to be used at cryogenic temperature settings.

Alloys steel has been designed with a variety of alloying elements. An AS Plate is alloyed between 1% to 50% of alloys that help in determining their properties. Characterized as low or high alloy components the Alloy Steel Sheet performs exceptionally well in different stress-induced environments suited to its characteristics. However, the higher alloyed components have superior hardness and strength compared to the latter allowing them to exhibit different AS Sheet Gauge thicknesses.

 

Chromium-molybdenum based alloy steel plates covered under the specification ASTM A387 are intended to be used for welded boilers along with pressure vessels. Designed for applications in elevated temperatures, the 4145 Alloy produced under this specification are available in the following grades i.e. - 2, 12, 11, 22, 22L, 21, 21L, 5, 9 as well as 91. Typically, the materials used to make Low Alloy Steel sheets are to be killed followed by being thermally treated. Aside from undergoing a heat analysis and product analysis, the 4140 Low Alloy strip must conform to the mechanical properties by undergoing tension tests in addition to the chemical properties.

 

If you're looking for a genuine Alloy Steel Plate Manufacturer in India, you've come to the right place, Low Alloy Steel Sheet in Boiler Quality Grades such as 4150/ 8620 is available from us.

 

4130 and 4140 AS sheets are chromium-molybdenum that can be differentiated based on certain aspects.

• 4130 Alloy Steel Sheet offers excellent machinability and weldability as compared to the modules of the 4140 grade.
• 4140 grade is designed with a superior chemical composition compared to the 4130 Plate. The versatile module of the 4130 Chromoly Plates is highly durable when compared to the 4140-grade modules.
• The items of 4140 grade possess superior mechanical properties over the 4130 grade.

 

Low alloy and carbon are the workhorses of the mechanical industry and can be distinguished based on certain features. Carbon is enclosed with alloys of iron, carbon, manganese, and silicon. Low Alloy Steel Sheet is similar to carbon grade components but possesses additional alloying elements like molybdenum, chromium, and many more, allowing it to possess a good heat response.

Chromoly sheets are components designed with an excellent composition of chromium and molybdenum. Chromoly Sheet is designed with lower carbon concentrations, allowing them to be ductile, durable, and an excellent weight saver. Chromoly Steel Plate shows enhanced properties of hardenability and corrosion resistance as well as possessing good strength at different temperatures.

The stiffness and strength of the Chromoly Plates at such junctures remain the same, making them a good choice in high-end bicycle frames, race car chassis, or aircraft fuselages across different Alloy Steel Plate Grades.

 

• 4140 grade is designed with a higher carbon and manganese content allowing it to possess excellent hardness than the 8620 grade. 8620 Steel Plates exhibits the presence of nickel in its concentration giving it enhanced resistance and tolerance in carburizing and corrosive media.
• The mechanical properties of the 4140 grade are superior; however, the 8620 components can suffice better in higher thermal conditions.
