About products
Medium carbon quenched and tempered structural steel is commonly used. "This steel has a general cold plasticity, slightly better during annealing and normalizing than during quenching and tempering, and has higher strength and better machinability. After proper heat treatment, it can obtain a certain degree of toughness, plasticity, and wear resistance, with convenient material sources.". Suitable for hydrogen welding and argon arc welding, not suitable for gas welding. Preheating is required before welding, and stress relieving annealing should be performed after welding. Normalizing can improve the cutting performance of blanks with hardness less than 160HBS. After quenching and tempering, the comprehensive mechanical properties of this steel are better than those of other medium carbon structural steels, but its hardenability is relatively low, with a critical hardenability diameter of 12 to 17 mm in water, and there is a tendency for cracking during water quenching. When the diameter is greater than 80mm, its mechanical properties are similar after quenching and tempering or normalizing. High strength and toughness can be obtained by quenching and tempering medium and small mold parts. Able to make rivet core with break out core
