Usage: 15cd35. It is commonly found in various fields of mechanical preparation and manufacturing, such as aerospace, machinery manufacturing, etc. It is commonly used in the manufacture of gears, bearing housings, pins, bolts and other mechanical parts, and can also be applied to the manufacture of parts with high load and high precision requirements.
Characteristics: Low alloy carbon steel: 15cd35 is a low-alloy carbon steel that contains a small amount of alloying elements, such as molybdenum, chromium, etc. The addition of these alloying elements gives it a certain strength and wear resistance, and has better comprehensive properties than ordinary carbon steel.
Medium carbon content: 15cd3The carbon content in 5 is moderate, which is conducive to improving its hardness and strength. This makes it suitable for applications that require a certain strength and abrasion resistance.
Adjustable quality: 15cd35. Its hardness and strength can be adjusted by heat treatment, quenching and tempering. This allows it to meet the needs of different applications and achieve the desired mechanical properties.
Good solderability: 15cd35. It has good weldability, which can be processed and connected by conventional welding methods. This makes the manufacturing and repair process much easier.
In summary, 15cd35 is a kind of low-alloy carbon steel widely used in the field of mechanical preparation manufacturing, with moderate carbon content, adjustable quality, good weldability and certain strength and wear resistance. It is suitable for the manufacture of mechanical parts that require strength and wear resistance, and its mechanical properties can be adjusted according to the needs during the heat treatment process.
