Steel coil ST37-2 is a grade of hot-rolled steel coil that is commonly used for general purposes such as manufacturing pipes, structures, and machinery. It is a low carbon steel with a minimum yield strength of 235 MPa and a tensile strength ranging from 360 to 510 MPa, making it relatively strong and ductile.
The hot-rolling process involves heating the steel above its recrystallization temperature and then passing it through rollers to reduce its thickness. This results in a material with improved mechanical properties and a smoother surface finish compared to cold-rolled steel.
Due to its versatility and cost-effectiveness, steel coil ST37-2 is widely used in various industries such as construction, automotive, and manufacturing. However, it may not be suitable for high-stress applications or environments with extreme temperatures due to its lower alloy content.
Overall, hot rolled steel coil ST37-2 is a reliable and popular choice for general purposes that require a balance between strength, ductility, and affordability.
