What is the application of 45# hot-rolled steel plates?

Hot-rolled steel plates are divided into structural steel, low-carbon steel and welded steel, and 45# steel is a kind of high-quality carbon structural steel, so 45# steel is hot-rolled steel. 45# steel is a medium carbon structural steel with good cold and hot workability, good mechanical properties, low price and wide sources, so it is widely used. Its biggest weakness is its low hardenability, large cross-sectional dimensions and high-demand workpieces.

45# hot-rolled steel plates are widely used in machinery, used to make small cross-section quenched and tempered parts with heavy load and large normalized parts with low stress, as well as surface hardened parts that do not require high core strength, such as tips, guide posts, Parts such as hands.
