S235JR typically contains low carbon, manganese, phosphorus, sulfur, and trace amounts of other elements. In CNC machining S235JR, we use carbide or high-speed steel tools for turning, milling, and drilling. We maintain proper speeds, feeds, and coolant for good results. It's weldable, but post-weld machining may be necessary for certain applications. S235JR is commonly used in various construction and structural applications, such as buildings, bridges, and machinery.

"S'' stands for structural steel. The numerical component "235" represents its minimum yield strength in megapascals (MPa), indicating the amount of stress the material can withstand before deformation. Additionally, the "JR" signifies that the steel has undergone a Charpy V-notch impact test at room temperature, ensuring a specified level of impact resistance.
