AISI 4130 4140 Alloy Boiler Steel Plate 

Alloy Steel Plates are steel these are alloyed with a different elements in overall quantities among 1.0% and 50% by weight to enhance its mechanical properties. Alloy steels have to type which is low-alloy steels and high-alloy steels. The difference between the two is relatively arbitrary. Alloy steel plates are defined as steel plates with a definite range or definite minimum quantity of additional elements, depending on the alloy. Classification of alloy steel According to the content of alloy elements Low alloy steel (the total amount of alloy elements is less than 5%), medium alloy steel (the total amount of alloy elements is 5%-10%), high alloy steel (the total amount of alloy elements is more than 10%). According to alloy element composition （Cr-Fe-C）、（Cr-Ni-Fe-C）、（Mn-Fe-C）、（Si-Mn-Fe-C） AISI 4130/4140 Alloy Steel plate Introduce AISI/SAE 4130 grade is a low-alloy steel containing chromium and molybdenum…
