Metal Super SNB-7 Polished Round Bar (H)

Metal Super SNB-7 Polished Round Bar (H)

Cutting sales available! Introduction of the polished round bar made of iron SNB-7.

At Yamamoto Tech Co., Ltd.'s online metal materials sales, "Metal Super Dot Com," we offer the 'SNB-7 Polished Round Bar (H).' This product has an outer diameter tolerance of h9 and is available for cutting sales starting from φ14. (Note that for φ13 and below, it may come with leftover material.) Small diameter round bars (up to φ13) are cut using a ponse method, while cutting from φ14 is done with a circular saw. Cutting with a lathe provides the cleanest cut surface, but it increases costs. Please contact us for pricing. *For more details, please refer to the PDF document or feel free to contact us.

Understanding the hardness changes of spring steel through quenching experiments and cooling rates.

Understanding the hardness changes of spring steel through quenching experiments and cooling rates.

[Reproduction of Private Spring Preparatory School Lecture 55] The harder the quenching, the greater the hardness! It also explains that there are differences in hardenability depending on the type of steel.

Today, let's try studying along with the experiment. Do you have a round bar made of spring steel? If possible, a diameter of about 25 millimeters would be ideal. Please cut this to a length of 10 centimeters and heat it to the quenching temperature. Once the steel bar is sufficiently heated to the quenching temperature, take it out of the furnace and place one end of the steel bar under a faucet with the spout facing upwards, allowing the water to spray onto it. The water will spread out like an umbrella when it hits the red-hot steel bar. After waiting for a while like this, cool the steel bar until it turns black. What changes will the steel undergo? *For detailed content of the article, you can view it in the PDF. For more information, please feel free to contact us.*
