Understand the characteristics and uses of 45# steel
2024-06-19 11:041、 Characteristics of 1045 steel
1045 steel is a commonly used medium carbon quenched and tempered structural steel with good machinability and strength. By using appropriate heat treatment methods, it can achieve certain toughness, plasticity, and wear resistance. This steel has general cold plasticity and is easier to process in the annealed and normalized state than in the quenched and tempered state. It is suitable for small and medium-sized mold parts and some large parts.
2、 The purpose of 1045 steel
1045 steel is widely used in industries such as mechanical manufacturing, steel metallurgy, automotive manufacturing, and shipbuilding. In the field of mechanical manufacturing, 1045 steel is commonly used to manufacture components such as gears, sprockets, reducers, bearings, etc. It is particularly suitable for the spindle and transmission parts of medium-sized machine tools such as large lathes, milling, and grinding.
In the field of steel metallurgy, 1045 steel is often used to manufacture electric furnace bases, steel wire ropes, steel bars, steel pipes, etc. In the field of automotive manufacturing, 1045 steel is also commonly used to manufacture automotive transmission shafts, universal joints, impeller shafts, etc. In addition, 45 steel can also be made into some mechanical parts, irregular shafts, and spiral springs.
3、 Applicable welding methods for 1045 steel
1045 steel is suitable for hydrogen welding and argon arc welding, but not very suitable for gas welding. Preheating treatment is required before welding; After welding, stress relief annealing is required.
