Description
Product Application
1.7228 steel (also known as SAE 4130) is a low alloy steel, which is standardised by EN10083-1. This steel has good hardenability and weldability, and is commonly used in aerospace, automotive, and mechanical engineering industries.
The specific chemical composition is as follows:
Carbon (C): 0.28-0.33%
Silicon (Si): 0.15-0.35%
Manganese (Mn): 0.40-0.60%
Phosphorus (P): maximum 0.035%
Sulfur (S): maximum 0.040%
Chromium (Cr): 0.80-1.10%
Molybdenum (Mo): 0.15-0.25%
The tensile strength of this steel is 850-1000MPa, yield strength is 460-570MPa, and elongation is 20-30%.
It can be in the annealed or quenched state.
Advantages:
1. Good hardenability, providing good strength and toughness through heat treatment;
2. Easy to weld;
3. Good corrosion resistance.
Disadvantages:
1. The low carbon content may result in lower hardening effect;
2. Common forms may be limited by the capabilities of processing equipment.
The most common forms of this steel include round bars, square bars, flat bars, and tubes.
Comparison of grades in various countries are as follows:
Chinese grade: 1.7228
American grade: SAE 4130
German grade: 25CrMo4
British grade: 708A25
Japanese grade: SCM430
Summary:
1.7228 steel is a low alloy steel with good hardenability and weldability, commonly used in aerospace, automotive, and mechanical engineering industries. This steel has high tensile and yield strength, good elongation, and good corrosion resistance. However, its low carbon content may result in lower hardening effect, and its most common forms may be limited by processing equipment capabilities.
