Structural Steel
S355 J2G3 STEEL
S355 J2G3 Steel is a carbon manganese ,high yield non alloy steel. It is called S355 because of the average minimum yield for this material is 355 Mpa.As a structural steel,it has excellent strength and weldability.It can be readily welded to other weldable steel. For its low carbon equivalent, it possesses good cold-forming properties.
S355J2G3 is a low carbon structural steel grade often used for application which require better mechanical properties than that of S275 and S235 grade.It is widely used in engineering and construction industries.
Applications include axles, bolts and connecting rods, motor, hydraulic and pump shafts, machinery parts,transmission towers, dump trucks, cranes, trailers, bull dozers, excavators, forestry machines, railway wagons, dolphins, penstocks, pipes, highway bridges, building structures, oil and gas platforms, offshore structures, shipbuilding, power plant, palm oil equipments and machineries, fans, pumps, lifting equipments and port equipments etc.
ST52 STEEL
ST52 is low-carbon steel with manganese content. It has good impact resistance and material strength. Durable properties combined with ease of processing makes ST52 a popular option for various industries and application. In terms of other physical resilience parameters such as surface hardness and tensile strength, ST52 shows good performance. In addition, ST52 is quite ductile, meaning it can be plastically reformed into desired shapes without any need for heat treatment.
. It is a standardized grade of steel in Europe, primarily Germany, where it is known as “Stahl St52” or “St52 Stahl” in German. In terms of its American equivalent, ST52 steel corresponds to ASTM A572 Grade 50 steel.
The key characteristics of ST52 steel include its high strength, good weldability, and good machinability. It is commonly used in the construction of buildings, bridges, and other structures where high-strength materials are required. ST52 steel is also employed in the manufacturing of machinery parts, such as hydraulic cylinders, axles, and various components that must withstand heavy loads and stress.
S275JR STEEL
S275JR is a specific grade of low carbon structural steel is the meaning
“S” is for structural steel;
“275” refers to the minimum yield strength is 275 MPa tested with steel thickness ≤ 16mm.
“JR” means that the minimum charpy impact value at room temperature is 27J.
“J0” refers to the minimum charpy impact value at 0 °C is 27J.
“J2” means the minimum impact value at -20 °C is 27J.
The choice of steel grade depends on the specific requirements of the project and the structural elements being used. Engineers and designers select the appropriate steel grade based on factors such as load-bearing capacity, environmental conditions, and the desired strength and durability of the structure.
