1045 Carbon Steel Tube Commonly used medium carbon quenched and tempered structural steel. The steel cold plasticity is general, annealing, normalizing than tempering is slightly better, with higher strength and better machinability, after appropriate heat treatment can obtain certain toughness, plasticity and wear resistance, the source of materials is convenient. Suitable for hydrogen welding and argon arc welding, less suitable for gas welding. Preheating is required before welding, and stress relief annealing should be carried out after welding.

Processing Requirements of 1045 Carbon Steel Tube:
1) 45 steel is high-quality carbon structure steel, hardness is not high easy to cut processing, molds are commonly used to make templates, tips, guide columns, etc., but heat treatment.
2) The parts after quenching and tempering have good comprehensive mechanical properties and are widely used in various important structural parts, especially those connecting rods, bolts, gears and shafts working under alternating loads. However, the surface hardness is low and it is not wear-resistant. It can be used to quench and temper + surface quench to improve the surface hardness of parts.
