What Materials Are Available For Drill Screws?
Drill-tail screws are widely used in life, which can be divided into carbon steel drill-tail screws and stainless steel drill-tail screws by material. Commonly used stainless steel materials SUS304, SUS316, SUS410, etc.
A. SUS304 stainless steel drill screws.
SUS304 stainless steel is a general-purpose stainless steel. Strong rust resistance, no need to do heat treatment, the application is very wide, mainly used in the production requirements of good comprehensive equipment or machine parts. The main requirement and standard of comprehensive is to require steel with corrosion resistance. Requirements must contain more than 18% of chromium as well as more than 8% of nickel, so 304 stainless steel has good corrosion resistance.
B. SUS316 stainless steel drill screws
SUS316 stainless steel drill-tail screws have added Mo to the basic composition of stainless steel, so 316 stainless steel has excellent corrosion resistance, and is also resistant to atmospheric corrosion. It has the advantage of being used in harsh conditions. For example, it is used in direct contact with rainwater, strong acid and alkali, climatic humidity, seaside, chemical plants and other occasions.
C. SUS410 stainless steel drill-tail screws
SUS410 stainless steel drill-tail screw is martensitic stainless steel, magnetic, the main feature is that it can be heat-treated to improve the core hardness and surface hardness, has a very high comprehensive mechanical properties, rust resistance than stainless steel is poor, better than carbon steel. Although SUS410 has high comprehensive mechanical properties, but corrosion resistance is not high.
D. Carbon steel drill-tail screws
Carbon steel drill tail screws 1022A standard heat-treated steel can be used as drill tail screw production materials, heat-treated surface hardness HV560-750, the heart hardness HV240-450, ordinary surface treatment, easy to rust, high hardness, low cost.
The above is a brief introduction to the material of drill tail screws, I hope it will be helpful to you.
