For example: razor, high heels heart, tape measure, wood saw, garden tools (flowery shear), bicycle chain, mostly used in high-carbon steel made

Compared to general commercial-grade steel (such CQ1 is CQ2 is, CQS, DQ, DDQ, 270C, 270D, 270E, etc.), the less market demand for high carbon steel and its applications familiar, in fact, high-carbon steel products general in the presence of our daily lives, but we are learning but have not checked it.Further discussed in the industrial or engineering applications, is more extensive.

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.
