Meet 35S20 Steel Grade: The Unsung Hero of Manufacturing

The 35S20 steel grade is an important material commonly used in manufacturing processes. Despite being an unsung hero, it plays a crucial role in the production of various products.

Mechanical Properties:
– Tensile Strength: The 35S20 steel grade exhibits a high tensile strength, which refers to its ability to withstand pulling forces without breaking or deforming.
– Yield Strength: It also has a significant yield strength, which indicates its ability to resist deformation under a specific amount of stress.
– Hardness: This steel grade has a hardness rating, usually measured on the Rockwell scale, that determines its resistance to indentation or scratching.
– Toughness: 35S20 steel possesses toughness, which means it can absorb energy and resist fracture under impact or sudden loading conditions.
– Ductility: This steel grade demonstrates good ductility, allowing it to be shaped or formed without fracturing or breaking easily.
– Bendability: Its ability to bend without cracking or breaking makes it suitable for various manufacturing processes such as sheet metal forming.

Chemical Composition:
– Carbon (C): The carbon content of 35S20 steel is typically between 0.18% and 0.24%. Carbon increases the hardness and strength of the steel but decreases its ductility.
– Silicon (Si): Silicon, present in small quantities in this steel grade, assists in deoxidizing the molten steel during the manufacturing process and improves its strength.
– Manganese (Mn): Manganese is added to enhance the hardenability, strength, and wear resistance of the steel.
– Sulphur (S): Sulphur is a typical impurity in steel, but its controlled presence in 35S20 steel improves machinability.
– Phosphorus (P): Phosphorus is also a common impurity, but in controlled amounts, it improves the strength and machinability of the steel.

Overall, the 35S20 steel grade possesses favorable mechanical properties, including high tensile and yield strength, good hardness, toughness, ductility, and bendability. Its chemical composition, with controlled amounts of carbon, silicon, manganese, sulphur, and phosphorus, further enhances its properties, making it an essential material for various manufacturing applications.
