4130 (E4130) alloy steel plate price in china

Aircraft quality 4130 (E4130) alloy steel plate is a medium carbon, low alloy steel containing 0.15/0.25% molybdenum and 0.80/1.10% chromium as strengthening agents. With the proper heat treatment it is also readily machined. Annealing 4130 (E4130) alloy steel offers excellent ductility. 4130 steel can also be normalized or otherwise heat treated. Steel 4130 (E4130) has an excellent strength to weight ratio and is considerably stronger and harder than other standard grades of steel. Chromoly steels are especially useful in their ability to retain their bulk properties while allowing for significant hardness to be attained.

4130(E4130) alloy steel plate , also referred to as Chromoly Steel and SAE/AISI 4130, is a chromium and molybdenum alloy steel. Known for its responsiveness to mechanical and heat treatments, 4130(E4130) alloy steel plate is weldable by most commercially popular methods. Cold working is possible and forming often takes place in the annealed condition. It is important to note that the machining of 4130(E4130) alloy steel plate is difficult when the hardness of the alloy increases. Alloy Steel 4130 is popular in a number of critical industries such as aerospace, automotive, and oil and 4130(E4130) alloy steel plate gas.

4130 (E4130) steel alloy steel plate is used primarily in the construction of commercial and military aircraft and ground support systems as well as automotive, race cars, off road, hydraulic tools, and machine tool applications. It is an intermediate strength material. Lighter gauges offer lighter weight but still maintain great strength, making it excellent for auto racing and aerospace. Engineers also use 4130 plate and bar steel for parts such as pins used to secure a critical assembly. These pins are designed to fail at a specific yield in order to avoid a catastrophic failure, and 4130 (E4130) alloy steel plate stands up to this test.
