ST52-3 STEEL
What is ST52-3 Steel ?
ST52-3 steel round bar is a type of low-alloy, high-strength steel that is also referred to as HSLA steel. St52 is a German grade (DIN 17100) equivalent to S355 in EN standards. The “St” stands for Stahl (German for steel), and “52” represents the minimum tensile strength of 52 kgf/mm² (~510 MPa).
It is widely used for manufacturing various industrial as well as domestic products and applications. It is equivalent to Indian IS2062 E350 grades of steel and EN S355JR and JIS SM490A. The ST52-3 round bar is known best and appreciated for its application-specific design, durability, dimensional accuracy, workability, weldability, excellent corrosion resistance, and long service life. These round bars are used in heavy-duty industries for several purposes.
The material is known for its excellent strength, toughness, and ductility, making it suitable for use in various applications. The chemical composition of ST52-3 steel includes elements such as carbon, manganese, silicon, phosphorus and sulphur.
One of the key properties of ST 52-3 steel is its high yield strength, which allows the material to withstand high-stress levels without undergoing significant deformation. The material also has good impact resistance, making it suitable for use in applications that involve dynamic loading or impact. Additionally, ST 52-3 steel has good weldability, making it easy to join using various welding techniques.
Further information on ST52 steel
ST 52-3 steel is commonly used in the construction industry to manufacture various structural components such as beams, columns, and plates. The material is also used to manufacture mechanical components such as shafts, gears, and gears. Additionally, it is used in the automotive industry to manufacture various components such as frames, suspension systems, and drive shafts.
The manufacturing of ST 52-3 steel typically involves a process of casting, followed by hot rolling, annealing, and normalizing, depending on end use. The material is then cooled and tempered to achieve the desired mechanical properties. The steel is then inspected and tested to meet the required specifications.
ST 52-3 steel is available in various forms, including plates, sheets, bars, and tubes. The material can be further processed through machining, cutting, and welding to create the desired product.
One of the advantages of ST 52-3 steel is its high strength-to-weight ratio, which makes it an ideal material for use in applications where weight is a critical factor. The material has good formability, making it easy to fabricate into complex shapes. It also has good machinability, allowing for easy and efficient machining operations.
ST 52-3 steel also has good corrosion resistance properties, making it suitable for various environments. However, it’s important to note that the corrosion resistance properties of the steel can be improved by applying a coat of paint or other protective coatings.
What are Limitations of ST52-3 Steel ?
There are some limitations to using ST 52-3 steel. The material is not suitable for use in applications that involve high-stress levels, as it may exhibit brittle behaviour under such conditions. Additionally, the material is not ideal for use in extremely high-temperature environments, as its strength and ductility may be adversely affected at such temperatures.
