Addressed if more industrial or engineering applications. Compared to the normal commercial grade steel (such as JSC 270C, the JSC 270D, JSC270D, JSC270D, etc.), the less market demand for high carbon steel, and its applications are relatively unfamiliar, in fact, in the high-carbon steel products & P in the presence of our daily lives , but we are learning without check only. For example: the tabs on the utility knife, stapler, tape measure, the 3C (mobile phones, desktop computers, notebook computers) parts, gardening tools (flower scissors), bicycle chain, mostly used in high-carbon steel made.

Hot-rolled products production process
1. Production process of hot-rolled products can be divided into hot-rolled quenched and tempered steel coils (HRC), pickling oiled steel coil (PO), pickling annealing coil (PA) and pickling spheroidized steel coils (PA -S) and other four categories.
2. Hot rolled coil output, quenched and tempered rolling and leveling the finishing line after a hot rolled quenched and tempered steel coils (HRC).
3. HRC pickling process descaling, and then coated with anti-rust oil antirust pickling oiled steel coil (PO), PO hardness, poor formability. In order to improve the moldability, the general first HRC pickling to descaling and then annealed (annealing) process, changes its microstructure, lower hardness, improved formability. Annealing can be divided into general annealing and ball annealing, the former is called pickling annealing steel coils (PA), which is called pickling ball or coils (PA-S) after annealing steel coils need Reapply oil rust prevention.
