4130 alloy steel is a low-alloy steel that contains molybdenum and chromium as strengthening agents. It exhibits excellent mechanical properties such as toughness, machinability, good strength, and weldability.
This steel grade is a versatile alloy with a reasonable strength up to 600°F (315°C) as well as better atmospheric corrosion resistance. As one of AISI steels, it can respond well to mechanical and heat treatments compared to carbon steels. With its low carbon content, this alloy steel can be easily welded. It exhibits excellent overall combinations of toughness, strength, and fatigue strength.
4130 alloy steel is stronger and harder compared to other standard steel grades. The alloy becomes suitable enough for machining as long as it has been heat-treated right after forging. Optimum strengths, conditions, and temperatures should be primarily defined to heat treat the material part.
Machining this alloy steel can be easy through the use of conventional methods. But when steel’s hardness increases, machining can be quite difficult. Forming the alloy is done in its annealed condition.
Since this alloy is readily machinable, machining simple shapes might follow a normalizing treatment, but machining complex shapes will need annealing. A coarse pearlitic structure with minimum ferrite is great for optimum machinability.
Uses of 4130 Alloy Steel
This low-alloy steel has many applications such as forgings in aerospace construction and oil and gas industries, agricultural and defense, and in automotive.
This the following applications of 4130 alloy steel;
- Welding tubing
- Aircraft engine mounts
- Commercial aircraft
- Auto racing
- Machine tools
- Forged valve bodies and pumps
- Military aircraft
- Hydraulic tools
