1.3243 Steel Forging Technology The alloy element content of M35 steel is more than 22%. It is higher than M2 steel about 30%. It’s forging is difficult. You need to pay attention to it as the same as M42 steel forging. First of all, preheat it fully, the heat temperature is 1120℃ – 1150℃. And the temperature of the beginning is 1000℃ – 1050℃, the ending of it is must higher than 899℃. After forging, it should cold slowly and annealing on time to prevent cracking. M35 Steel Annealing Process If you case it up for the annealing after the forging, you will get a better result. If you can not do that, just make it cold to the indoor temperature then make it in. About the annealing process, just put it in the stove with the temperature which is lower than 500℃. Then heat to 840-860℃, keep the temperature for four to five hours. Furnace cooling to 500℃ below than out of it. Cooling slowly in the annealing furnace. After the annealing, its hardness is lower than 255HB. In order to prevent oxidative decarburization happen, the annealing should be careful. And there is an easy way can do that. Just put some wood dust to the annealing furnace. Notice for Quenching and Tempering Preheat two times: 600℃, 860℃. And the time of preheating is twice the time of heating. The request of quenching is 10-12s/mm. Needs the step hardening: 600℃→260-280℃→air cooling. The temperature of secondary hardening is 535-540℃ around. The hardness is bigger than 68HRC for after tempering. But the factories do not want the hardness of cutting tool is more than 68HRC due to the request for production. So it always is been tempering. As we can see from the table, the best temperature for quenching is in the range of 1215-1225℃. In this condition, it is suitable for annual cutting tools. Its hardness is about 67-67.5HRC. It satisfies the needs of high speed steel high speed steel for high strength, high hardness and high wear resistance. M35 steel that been quenching at the temperature below 1190℃ is good material for cold work die and low-speed cutting tools. And if it been quenching at the temperature higher than 1230℃ which will have a great red hardness. It will be a good choice for turning tools and etc. Quenching it in that way will cause overheating. But it is not a trouble, the key is to control it in the right way. Some cutting tools are overheating to be more useful. In China, we have been focusing on the steel industry for decades, as a professional supplier, a powerful steel factory, advanced technology, high- quality steel, we have our own cutting and processing facilities. Specific specifications can be customized and customized according to your needs. Provide reliable M35 high speed steel products as well as other high speed steels high speed steels, please contact us for any needs of high speed steel M35 steel.

What is AISI 4140 Steel? AISI 4140 alloy steel round bar sheet plate belongs to medium hardenability steel.AISI 4140 steel has high fatigue strength and low notch sensitivity. Low- temperature impact toughness is also very high, no obvious temper brittleness. AISI 4140 steel round bar is mainly used after quenching and tempering state. it is used to manufacture high-strength parts under impact loads and the fittings with large cross-sections and other stressed members. Such as the horizontal eccentric shaft of the horizontal forging machine, the crankshaft of the forging press, and etc. Its equivalent grade is JIS SCM440 and DIN 1.7225. The properties and composition of 4140 steel round bar sheet plate as below. AVAILABLE SIZE: Round bar: Diameter(mm) Max 800mm; Length(mm) Max 12000mm. Plate: Thickness(mm) Max 800mm; Width(mm) Max 2300mm; Length(mm) Max 12000mm. Condition: Cold rolled(drawn)≤50mm, Hot rolled≤12-250mm, Hot forged≥50mm. AISI 4140/DIN 1.7225 Introduction: AISI 4140 alloy steel is chromium, molybdenum, manganese containing low alloy steel. It has high fatigue strength, abrasion and impact resistance, toughness, and torsional strength. Fabrication and Heat Treatment: 1. Forging Preheat the steel carefully, then raise the temperature to 1150-1200°C for forging. Do not forge below 850°C. 2. Annealing Heat the AISI 4140 slowly to 800-850°C and allow enough time for the steel to be thoroughly heated. Cool slowly in the furnace to 480°C followed by air cooling. 3. Stress Relieving When parts are heavily machined, ground or otherwise subject to cold work, stress relieving will be beneficial prior to hardening. 4. Hardening AISI 4140 steel is usually supplied ready heat treated to 18-22HRC. If further heat treatment is required annealed AISI 4140 should be heated slowly to 840- 875°C and after adequate soaking at this temperature quench in oil. Temper as soon as the tools reach room temperature. 5. Tempering Heat the AISI 4140 carefully to a suitable temperature selected by reference to a tempering chart or table (usually between 550-700°C, soak at the temperature for 2 hours per 25mm of ruling section, then allow to cool in air. Tempering between 250-375°C is not advised as tempering within this range will seriously reduce the impact value. 6.

high speed steel composition forged high speed steel composition supplier High-speed steel (HSS) is a tool steel with high hardness, high wear resistance and high heat resistance, also known as high-speed tool steel or front steel, commonly known as white steel. High-speed steel was created in 1898 by F.W. Taylor and M. White in the United States. High-speed steel has good process performance, good strength and toughness, so it is mainly used to manufacture complex thin-edged and impact-resistant metal cutting tools, as well as high-temperature bearings and cold extrusion dies. In addition to the high-speed steel produced by the smelting method, powder metallurgy high-speed steel appeared after the 1960s, which has the advantage of avoiding the reduction of mechanical properties and heat treatment deformation caused by the segregation of carbides produced by the smelting method. Craftsmanship The heat treatment process of high-speed steel is more complicated, and it must go through a series of processes such as quenching and tempering. Quenching is generally carried out in two stages due to its poor thermal conductivity. First preheat at 800 ~ 850 ℃ (to avoid causing large thermal stress), then quickly heat to the quenching temperature of 1190 ~ 1290 ℃ (the actual temperature of different brands is different), and then oil cooling or air cooling or gas cooling. The factories are all heated by salt furnaces, and vacuum furnaces are also widely used. After quenching, a part (about 30%) of retained austenite remains in the internal structure and is not transformed into martensite, which affects the performance of high-speed steel. In order to transform the retained austenite and further improve the hardness and wear resistance, it is generally necessary to carry out 2 to 3 tempering times, the tempering temperature is 560 ° C, and the temperature is kept for 1 hour each time. Production method: Usually electric furnace is used for production, and powder metallurgy method was used to produce high-speed steel, so that the carbides are evenly distributed on the substrate in the form of extremely fine particles, which improves the service life. Uses: used to manufacture various cutting tools. Such as turning tools, drills, hob, machine saw blades and molds with high requirements. Songshun specialized in Special Steel for almost 20 years.

1.m2 steel is molybdenum-based high-speed steel, which has the advantages of small carbide inhomogeneity and high toughness. It is easy to overheat, so the quenching heating temperature should be strictly controlled, and the requirements for heat treatment protection are stricter. Due to its good hardness and wear resistance, it is mostly used to manufacture tools for cutting difficult-to-cut materials. M2 steel has a high tendency to carbides, so it has stricter requirements for heat treatment protection, and is suitable for molds that withstand vibration and impact loads. 2.AISI M2 Steel physical properties Factory hardness: ≤255HB Quenching temperature: 1220-1240 Hardness:≤63 3.1.3343 High Speed Steel Features Hardness (factory state): ≤255HB Curing Temperature: 1220℃-1240℃ Hardness (after heat treatment): ≤ 63 HRC It is a good choice for cutting applications due to its high wear resistance and toughness.
