SKH53 High Speed Steel SKH53 High Speed Steel

SKH53 Japan SKH53 High Speed Steel Standard (JIS G4403) % Economical high-speed tool steel is a high-carbon high-vanadium high-speed steel made by increasing the vanadium content on the basis of tungsten-molybdenum general-purpose high-speed steel SKH53. The steel has economy, fine and uniform carbide, high toughness, good thermoplasticity, but poor grindability and easy decarburization. Tools are manufactured to cut hard-to-cut materials.

High-carbon, high-vanadium high-speed steel formed in order to further improve the red hardness and wear resistance of steel, usually containing about 3% V steel. When the V content is 4%-5%, it is suitable for manufacturing cutting tools with simple shape or small grinding amount. SKH53 steel is not suitable for making complex tools due to its poor grindability.

It is used to make various types of general tools, such as broaches, profile milling cutters, hob cutters, drills, taps, turning cutters, planer cutters, etc. It is still possible to make more complex knives. It is suitable for processing medium and high strength steel, high-temperature alloys and other difficult-to-machine materials.

It can be completely replaced, and it is very suitable, both are materials of the same level, but when purchasing, we must pay attention to the real imported materials, and do not be indiscriminately filled.

SKH-51 high-speed steel

The standard grade JIS SKH-51 high-speed tool steel is an internationally used tungsten-molybdenum ductile high-speed steel, the carbide particles of the steel are fine and uniform, with high toughness, excellent cutting performance, good thermoplasticity and other characteristics, with good wear resistance, especially resistant to 600 high temperature is not easy to soften, good red hardness, hardness can reach 64HRC after heat treatment and quenching, wear resistance is 2 times higher than that of high-chromium high-carbon steel, and the durability is stronger, but its heat treatment process is more difficult than that of new high-speed steel.

SKH-9 high speed steel

SKH-9 high-speed steel is a high-performance tungsten-molybdenum ordinary melted high-speed tool steel with good toughness, it belongs to the same grade of steel as JIS standard SKH-51 high-speed steel, is the most versatile high-speed tool steel, currently used in the world, SKH-9 high-speed steel carbide structure is fine, neat, evenly distributed, with the plasticity of hot work die steel and cold work die steel, processing performance and grinding performance are also relatively good.

Key properties of SKH-51 high speed steel

The carbide structure is fine, neat, well distributed and uniform.

The abrasion resistance and toughness are relatively balanced.

The wear resistance is 2 times higher than that of high-chromium high-carbon steel, and the seamability is twice stronger.

It is rich in hot work and cold work plasticity, and has good cutting and abrasiveness.

Tungsten-molybdenum 652 high-speed tool steel is the most universal and can replace tungsten SKH2 high-speed tool steel.

Since the carbon content is increased or decreased, the properties of the steel can be continuously and significantly changed without damaging the high-temperature characteristics.

It can resist 600 high temperatures, it is not easy to soften, the red hardness is good, and the hardness can reach 64HRC after heat treatment and quenching.

To sum up the above characteristics, SKH-9 high-speed steel is widely used in various tools and advanced stamping dies for cutting with wear resistance and impact resistance, such as: screw dies, tools that require toughness and complex shapes, milling cutters, drill bits, scrapers, hobbing cutters, milling cutters, drill bits, forging dies, screw forming dies, taps, punches, knife edges, punch materials, etc.

Ingredient comparison

Yes, this is just the name of the two companies, and the material is the same.

SKH-51 high-speed steel is the general name of tungsten-molybdenum high-speed steel (alloy composition W6Mo5Cr4V2) by the Ministry of Industry of Japan. Each steel mill in Japan has a different product name for this type of steel, such as YXM1 for Hitachi, and SKH-9 for Fujikoshi in Japan. In China, tungsten and molybdenum high-speed steel (alloy composition W6Mo5Cr4V2) is collectively referred to as M2; Abbreviation:

SKH-9 high-speed steel is the product name of Fujikoshi Steel Mill in Japan, which is actually the same kind of high-speed steel produced according to the requirements of the Ministry of Industry of Japan for tungsten-molybdenum high-speed steel (alloy composition W6Mo5Cr4V2). Because the sales of this type of high-speed steel SKH-9 high-speed steel in Japan and Taiwan are very good, SKH-9 high-speed steel was later introduced to Chinese mainland by Taiwan-funded enterprises. It is called by everyone, and SKH-9 high-speed steel has become synonymous with tungsten-molybdenum high-speed steel (alloy composition W6Mo5Cr4V2).

Actually, SKH-9 high speed steel and SKH-51 high speed steel are the same category of high speed steel. However, there are more people who know SKH-9 high-speed steel on the market, so it has naturally become synonymous with the people.

SKH-51 is an international tungsten-molybdenum ductile high-speed steel, the steel carbide particles are fine and uniform, with high toughness, excellent cutting performance, good thermoplasticity and other characteristics, with good wear resistance, especially can resist 600 high temperature is not easy to soften, good red hardness, heat treatment and quenching hardness can reach 64HRC, wear resistance is 2 times higher than high chromium high carbon steel, the durability is stronger, the disadvantage is that the heat treatment process is difficult, the cost of use is high.

The most plus SKH-51 cutting tool industry, scraper, hobbing cutter, milling cutter, drill, etc.

Forging industry: forging molds.

Screw industry: hexagonal and other head forming molds, Hu quietly tapping

Stamping dies: punches, knife edges, punch materials.

Forging: annealing: heated to 800-850, staying at this temperature for two or four hours, and letting it cool down in the furnace.

Quenching: pre-heating to 550-600, subheating to 950, and then heating to a: 1,220 1250; b：

1，200℃～1230℃。It is hardened in oil, but the oil temperature must first be moisturized at 40-60 (a.).general tools; b.

Formal complexity requires the tools of toughness).

Tempering: Heating to 550-570, staying at this temperature, then cooling in still air, tempering must be repeated Secondary hardness: HRC63 or more.

High red-hot hardness, high wear resistance and cutting ability, high impact toughness, fine and uniform grains, and high toughness. SKH-51 is tungsten steel high-speed steel, which is suitable for the manufacture of wear-resistant, impact-resistant tools for strong cutting, advanced stamping dies, screw dies, tools that require toughness and complex shapes, milling cutters, drill bits, etc.
