30CrMo Steel Equivalent, Chemical Composition, Mechanical

30CrMo Steel. 30CrMo steel is a Chinese alloy steel for engineering and machine structural use, has high strength and high toughness, and has good high temperature strength at temperatures below 500 °C. 30CrMo material also has good machinability, medium cold bending and plasticity, high hardenability, good weldability, and is generally used in the adjusted state. 36 Types Of Thermomechanical Treatment Process (5) Extrusion immediate quenching of 35CrMo steel oil jumper joints The deformation temperature of extrusion is 11001200 and the tempering temperature is 570580. Hardness is 300 ~ 335HBW, mechanical properties of tensile strength is 1068MPa, flexural strength is 960MPa, elongation is 14.5%, which meets the requirements

42CrMo Steel Round Bar Sheet Plate Material - Zhijie Feng

42CrMo Steel Material is high strength steel. It has great toughness, strength and hardenability. After quenching and tempering treatment, it will get better fatigue limit and shock resistance ability. It usually is used without obvious temper embrittlement after the quenching and tempering treatment. And its low-temperature impact toughness is good. 42CrMo4 DIN 1.7225 Steel Round Bar Plate Material 42CrMo4 1.7225 Steel Round Bar Sheet Plate. 42CrMo4 steel is super high strength alloy steel with high hardenability and toughness and it has no temper brittleness. And it also be called DIN 1.7225 steel. After quenching and tempering, it will get high fatigue strength. Its impact toughness is great at low temperatures. Cheap Steel sleeve for rolling mill Manufacturers 3. Quenching. Quenching is the rapid cooling process in the quenching medium of water, oil, or other organic salts and organic water, after the heating of the workpiece. The steel is hardened after quenching, but it is brittle at the same time. 4.Tempering . Tempering is in order to reduce the brittleness of the steel core.

Comparison between 40Cr steel and 35CrMo steel - Bebon

Therefore, 35CrMo steel has higher hardenability and better tempering stability than 40Cr steel, and its grain growth tendency is small when quenched and heated, and there is no tempering brittleness tendency. Small parts can be air-cooled after tempering, and large parts should be quickly cooled after tempering, such as water cooling or oil cooling. Because Mo is a rare high melting point metal, the price of 35CrMo steel DIN1.7220 34CrMo4 ASTM 4135 Quenching and Tempering DIN1.7220 34CrMo4 ASTM 4135 Quenching and Tempering Steel. Description:Grade:DIN1.7220 34CrMo4. Standard:EN10083-3 (Technical delivery conditions for Alloy steels in the quenched and tempered condition) Shape:round, flat, square. Size Range:Steel-making Condition:EF, EF/EAF+LF+VD, EF/EAF+ESR. Delivery Condition:Hot forged, hot rolled, cold rolled, cold drawn. GB/T 3077 35CrMo Alloy Steel PlateHowever, this material has a first type of temper brittleness, and the weldability is not good. It needs to be preheated to 150-400 ° C before welding, and heat treatment is needed after welding to eliminate stress. Generally used after quenching and tempering treatment. 35CrMo Steel

Alloy structual steel. Grade:4140. 1.Introduction. 4140 belongs to ultra-high strength steel, has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multi-impact resistance after quenching and tempering treatment, such as large gears for locomotive traction, supercharger transmission gears, pressure vessel gears, rear axles, extremely loaded Strength characteristics of 35CrMo alloy structural steel 35CrMo alloy structural steel shall be preheated to 150-400 before welding, and post welding heat treatment shall be carried out to eliminate stress. 35CrMo alloy structural steel is generally used after quenching and tempering, and it can also be used after high and medium frequency surface quenching or quenching and low and medium medium carbon tempering steel on behalf of the steel C30 It has high hardenability. Calculated by 50% martensite, the water quenching diameter is 180, and the oil quenching diameter is 100.The tendency of quenching cracking ,and the tempering brittleness are small.High strength and high toughness.It can replace 35CrNiMoA, 4340, used to manufacture large section, heavy load shaft, connecting rod and bolt.

35CrMo structural alloy features steel plate,35CrMo

The plasticity of 35CrMo alloy is fair during cold deformation, and the machinability is medium, but it has the first type of temper brittleness. The weldability is not good. It needs to be preheated to 150~400 degrees Celsius before welding. Post-weld heat treatment is used to eliminate stress.
