Alloy steel Forging round bar
Alloy steel forged round steel refers to round steel made from alloy steel as raw material and processed through forging technology.
Features:
It has high strength, high hardness, good wear resistance, toughness, and fatigue resistance, which can meet the requirements of various complex working conditions.
Common materials:
Alloy structural steel:such as 20Cr, 40Cr, 42CrMo, etc., has good comprehensive mechanical properties and is widely used in the field of mechanical manufacturing.
Alloy tool steel:such as Cr12MoV, 9Cr2Mo, etc., has high hardness, high wear resistance, and good thermal stability, and is commonly used in mold manufacturing.
Stainless steel:such as 304, 316, etc., has excellent corrosion resistance and oxidation resistance, and is suitable for industries such as food, chemical, and medical devices.
Main applications:
1. Automotive industry: used for manufacturing key components such as engine crankshafts, half shafts, gears, etc.
2. Mechanical manufacturing: It can produce various shafts, gears, bolts and other parts, and is an important basic material for mechanical equipment.
3. Aerospace: Suitable for manufacturing components such as aircraft landing gear and engine blades that require extremely high performance.
4. Energy industry: used for manufacturing equipment parts such as pipelines, valves, and shafts in the fields of petroleum, chemical, and power.
