Hot-rolled SAE1055

medium carbon steel with a carbon content of 0.55%. It has a good balance of toughness, hardness, and wear resistance, making it suitable for use in high-stress applications. The hot-rolling process involves heating the steel above its recrystallization temperature and then passing it through a series of rollers to deform it at high temperatures. This process results in a product that is more ductile and easier to form than cold-rolled steel.

Hot-rolled SAE1055 has a smooth, shiny surface and can be easily welded, machined, and formed into various shapes. It is also a cost-effective material choice for many applications. Some of the common applications of hot-rolled SAE1055 include axles, crankshafts, gears, shafts, and springs.

The following are some product specifications of the hot-rolled SAE1055:

• Diameter range: 5.5mm-130mm;
• Steel length: fixed length and random length are optional, usually 3-12 meters;
• Surface state: smooth, no rust spots, ripples;
• Material control: chemical composition, mechanical properties and other indicators are stable, and there are perfect detection means for inspection;
• Application range: Mainly used in the manufacture of springs, mechanical parts, bearings, auto parts and so on.

In addition to the above specifications, hot rolled SAE1055 also has the following advantages:

• Good thermal processing performance, easy to shape processing;
• Good weldability, can meet the welding needs of different industries;
• Good toughness, can ensure durability.
