Steel tapping screws manufacturers according to your needs production

Steel tapping screws are general-purpose materials for the general industry, and different screws are produced according to the requirements of use. The application of steel tapping screws is very extensive, and the usage of various industries is also very wide.

Many times we usually say that the iron material is carbon steel, and the cast iron and carbon steel are both iron and carbon alloys. The fundamental difference between cast iron self-tapping screws and steel tapping screws is the carbon content. What is the difference between them?

The carbon content is 2.08% (some with a boundary of 2.11%) or more, and the following is steel. However, in practical applications, it is generally called wrought iron or pure iron with a carbon content of less than 0.03%, and the content is 0.1-1.7%. Steel is divided into low carbon steel according to carbon content (C ≤ 0.25%); medium carbon steel (C ≤ 0.25 ~ 0.60%); high carbon steel (C > 0.60%). Generally, medium and low carbon steel is structural steel, and high carbon steel is mostly tool steel. So in fact, iron and carbon steel materials are still somewhat different.

Steel tapping screws can be heat treated according to different requirements, and the strength can reach 6.8, 8.8, 10.9.
