Low alloy steels
Low alloy steels are a type of metal alloys with a small percentage of alloying elements such as silicon, manganese, stainless steel and other alloying elements. They are commonly used in a variety of applications due to their strength, wear resistance and ductility. Usually, the heating temperature of low alloy steels for hot forging is from 1050-1150℃.
Austenitic stainless steels
Austenitic stainless steels are one of the most common stainless steel alloys which shows good corrosion resistance, strength and ductility. It is a typically non-magnetic material and easy to be hot forged. The commonly forging temperature of austenitic stainless steels is from 1450-1650℃.
Ferritic stainless steels
Ferritic stainless steels comprise of about 11%-17% chromium and very little or no addition of nickel. Ferritic stainless steels have a higher specific magnetic susceptibility than austenitic stainless steels, making them only weakly magnetic. The common forging temperature of ferritic stainless steels varies from 1325-1500℃.
Maraging steels
Maraging steels are a family of low-carbon iron-nickel alloys which show high strength and toughness at room temperature with an extremely high strength-to-weight ratio. Traditional heat treatment processes such as age hardening and precipitation hardening can be used to improve the mechanical properties of maraging steels. The normal hot forging temperature of maraging steels is from 950-1100℃.
Tool steels
Tool steels are a type of alloy steels which contains a high percentage of carbon up to 1.5%, and iron as the main alloying element. Due to their high wear resistance, fatigue strength, tensile strength and hot hardness, they are widely used in cutting and forming applications. The common hot forging temperature of tool steels is from 1100-1300℃.
Superalloys
Superalloys are also known as high-performance alloys. Compared to ordinary steels, superalloys show good mechanical strength, creep and oxidation resistance at elevated temperatures. Due to their excellent properties and excellent combination of characteristics, superalloys are widely used in aerospace, power generation, and industrial applications. The usual forging temperature of superalloys is from 1300-1550℃.
