In the metal cutting industry, slitter is the most commonly used equipment, and the quality of circular knives directly affects the performance of the whole machine. The slitter needs long-term operation, so the materials for manufacturing circular knives need better mechanical properties, including its hardness, manufacturing process and wear resistance. At present, there are many kinds of blade materials in the world, most of which are made of steel. Here is a brief look at several commonly used circular knives materials.
Die steel
Cr12MoV
Carbon structural steel
45# carbon steel
T10A carbon tool steel
Alloy tool steel
Die steel is a kind of steel used to manufacture cold stamping die, hot forging die, die casting die and so on. Die steel is a common material for making blades.
Cr12MoV is a common high-quality die steel, which has high hardenability, quenching and tempering, and good hardness, strength and toughness. The quenching deformation is small, and the defect is poor plasticity at high temperature. It is generally used to manufacture blades with large section, complex shape and load resistance. It has a long service life and is generally used to cut high hardness plates such as stainless steel plate and silicon steel sheet.
Carbon structural steel is a kind of carbon steel. The carbon content is about 0.05% ~ 0.70%, and some can be as high as 0.90%. The carbon structural steel can be divided into ordinary carbon structural steel and high-quality carbon structural steel. There are many uses and large dosages. Many circular knives are made of carbon steel. There are many kinds of carbon steel, which can be used in a wide range.
45# carbon steel is a kind of high-quality carbon structural steel with easy cutting and good mechanical properties. The disadvantage is poor quenching performance and low heat treatment hardness. Therefore, quenching and tempering and high-frequency surface quenching are often used in the process, which is mainly suitable for non-metallic cutting.
T10A carbon tool steel also has excellent properties, high strength and wear resistance, but its disadvantages are low thermal hardness and low hardenability. It is generally used for cutting needs with low cutting conditions and high wear resistance, which is common in the cutting of ordinary A3 plates.
Alloy tool steel is an iron-carbon alloy formed by adding an appropriate amount of one or more alloy elements on the basis of ordinary carbon steel. According to different added elements and appropriate processing technology, alloys with special properties such as high strength, high toughness, wear resistance, corrosion resistance, low-temperature resistance, high-temperature resistance and non-magnetism can be obtained. Alloy tool steel is also a common raw material for manufacturing circular knives. It has outstanding performance in heat treatment, and its brittleness and hardness are very good.
