1035 steel high quality carbon structural steel (GB/T699-2015) has good plasticity and appropriate strength, good process performance, welding performance is fair, mostly used in normalizing and tempering state.
1045 is a kind of high quality carbon structural steel, corresponding to Japanese standard S45C, American standard: 1045, German standard C45. It is characterized by higher strength and deformation resistance than ordinary A3 steel.
1055 is medium carbon steel with high strength. It has high surface hardness and strength after treatment, but poor plasticity and toughness, medium cutting performance, poor weldability and hardenability, and water quenching has the tendency to form cracks. Generally in normalizing or quenching

1055 is generally in normalizing or quenchingAfter use, used for parts requiring higher strength and wear resistance or elasticity, dynamic load and impact load is not large,Such as gear, rim, flat spring, crankshaft, etc., can also be used as castings.
1045 steel is widely used in machinery, without heat treatment: HB≤229; Heat treatment: normalizing; Impact work: Aku≥39J; 45# steel plate after quenching without tempering, hardness greater than HRC55 (up to HRC62) is qualified, after heat treatment, and then tempering can reach HRC42-46, which can not only ensure its good mechanical properties, but also get the surface hardness requirements. Used for making small section tempering and tempering parts with large load and large normalizing parts with small stress, as well as surface quenching parts with low requirements on core strength, such as tips, guide posts, gauges and other parts.
1035 steel is widely used in the manufacture of all kinds of forgings and hot-pressed parts, cold-drawn and top-forged steel, seamless steel tubes, mechanical parts such as crankshafts, rotating shafts, shaft pins, levers, connecting rods, beams, sleeves, rims, washers, screws, nuts, motorcycle frames, etc.
