Product brief introduction

The steel annealing, normalizing is slightly better than the tempering, with higher strength and better machinability, after appropriate heat treatment can obtain a certain degree of toughness, plasticity and wear resistance. Suitable for hydrogen welding and argon arc welding, not suitable for gas welding. Preheating before welding, stress relief annealing after welding
