Choose 4145H or 4145H MOD for the stabilizer
4145H and 4145H MOD are two different steel specifications mainly used for high-strength and high-temperature applications in the petroleum and natural gas industries. Their differences lie in the following aspects: Chemical composition: There is a slight difference in the chemical composition b...Read more -
Quenching and tempering treatment
Quenching and tempering treatment refers to a dual heat treatment method of quenching and high-temperature tempering, which aims to ensure that the workpiece has good comprehensive mechanical properties. High temperature tempering refers to tempering between 500-650 ℃. Most quenched and tempered ...Read more -
Shaft Forgings for Hydraulic Turbines and Hydraulic Generators
1 Smelting 1.1 Alkaline electric furnace smelting should be used for forging steel. 2 Forging 2.1 Sufficient cutting allowance should be present at the upper and lower ends of the steel ingot to ensure that the forged piece is free from shrinkage cavities and severe segregation. 2.2 The forging...Read more -

Open forging parts
The basic processes of free forging include upsetting, elongation, punching, bending, twisting, displacement, cutting, and forging. Free forging elongation Elongation, also known as extension, is a forging process that reduces the cross-sectional area of the billet and increases its length. Elong...Read more -
Forging for rotor of industrial steam turbines
1. Smelting 1.1 For the production of forged parts, alkaline electric arc furnace smelting followed by external refining is recommended for steel ingots. Other methods ensuring quality can also be used for smelting. 1.2 Prior to or during the casting of ingots, the steel should unde...Read more -
Normalizing of the forging part
Normalizing is a heat treatment that improves the toughness of steel. After heating the steel components to a temperature of 30-50 ℃ above the Ac3 temperature, hold them for a period of time and air cool them out of the furnace. The main characteristic is that the cooling rate is faster than anne...Read more -

Manufacturing Equipment Flange manufactu...Read more -
Temper brittleness during forging and processing of forgings
Due to the presence of temper brittleness during forging and processing of forgings, the available tempering temperatures are limited. To prevent brittleness from increasing during tempering, it is necessary to avoid these two temperature ranges, which makes it difficult to adjust mechanical prop...Read more -
What are the heating methods for shaft forgings？
Continuous moving heating is commonly used for induction heating of shaft forgings, while high-frequency quenching heating usually involves fixing the inductor while the forging moves. Medium frequency and power frequency heating, often moved by sensors, and the forging can also rotate when neede...Read more -
