Historical development of alloy steel forgings

Every material in the industry has a long history, but today we are mainly talking about the historical development of alloy steel forgings.
From the second world war to the 1960s, alloy steel forgings were mainly the era of the development of high-strength steel and ultra-high-strength steel. Due to the needs of the aviation industry and the development of rocket technology, many new high-strength steels and ultra-high-strength steels appearedSteel grades, such as precipitation hardening high-strength stainless steel and various low-alloy high-strength steels, are its representative steel grades.After the 1960s, many new metallurgical technologies, especially the out-of-furnace refining technology, were widely adopted. Alloy steel began to develop in the direction of high purity, high precision and ultra-low carbon. Maraging steel and ultra-pure ferrite appeared again.New steel grades such as stainless steel.
