[Reproduction of Private Spring Preparatory School Lecture 31] Explaining how tempered martensite changes through tempering!
Now, just as some people fall while sliding down the same slope, there are those who can slide smoothly, similarly, even when steel is hardened under the same conditions, the degree of hardening varies. This is because the ease of hardening depends on the composition of the steel. For example, spring steel of type 11 contains a small amount of boron in addition to manganese and chromium, which allows it to be hardened even in thick diameters of 60 to 70 millimeters. I will explain this further later. So today, let's study how hardened martensite changes through tempering. *The detailed content of the article can be viewed in the PDF.

[Reproduction Private Spring Preparatory School Lecture 56] There are also restrictions on the components of special elements! The composition of JIS spring steel is also determined by this.
The components that increase hardenability are manganese, chromium, silicon, and especially boron, which has a significant effect even in small amounts. Now, if we keep adding such special elements, will the hardenability of spring steel increase, allowing us to make springs of any thickness? Not so fast. First, the properties of the steel will change, making it unsuitable for spring steel, and when it comes to thicker materials, shaping becomes very difficult. Being large is not necessarily a good thing. *For more detailed information, please refer to the PDF. Feel free to contact us for more details.*
Since it is prone to rust, surface treatment and other measures are necessary! Introduction to carbon tool steel.
Spring steel and carbon tool steel with carbon content of 0.4% or more increase in hardness by 2 to 3 times through heat treatment (quenching). By processing in a soft state before heat treatment and then increasing the hardness afterwards, complex shapes can be formed. They are characterized by low heat resistance and strong magnetism. As a note, they are prone to rust, so surface treatment measures are necessary. 【Overview】 ■ Carbon tool steel, etc., increases in hardness by 2 to 3 times through heat treatment (quenching) ■ Complex shapes can be processed by increasing hardness afterwards ■ Characterized by low heat resistance and strong magnetism *For more details, please refer to the related links or feel free to contact us.
