Answers

Why are the selection parameters for pull-out anchors so important?
The core value of pull-out anchors lies in transferring structural loads to deep, stable strata. However, many purchasers only focus on the pull-out force value, neglecting:
Deformation compatibility: Excessive deformation differences between the anchor and the surrounding soil can lead to stress concentration.
Corrosion tolerance: The erosion rate of metal anchors by underground chemical environments can vary by more than 10 times.
Construction error tolerance: Drilling deviations have drastically different effects on the bearing capacity of different types of pull-out anchors.
For example, in water-rich strata, using mortar pull-out anchors with anti-corrosion coatings can extend the lifespan by 3-5 years compared to ordinary steel strand anchors. These hidden costs are often only recognized after an accident occurs.
What alternative materials can be used for carbon steel Q195?
Q195 is a low-carbon structural steel. Finding a suitable alternative depends on the specific application.
Some common alternative materials are listed below for reference only:
Q215 has slightly higher strength than Q195, and its applications are largely the same.
DC01 corresponds to the national standard Q195/Q215, with a tensile strength of 270-410 MPa and a yield strength of 130-260 MPa.

When selecting an alternative material, the most crucial factor is to clearly define the specific application, processing method, and minimum requirements for mechanical properties.
The carbon and manganese content of alternative materials may differ from that of Q195, which will affect their welding, forming, and other process properties, requiring corresponding adjustments to the manufacturing process.
What's the difference between stainless steel bearings and ordinary bearings?
Bearing steel generally has a higher carbon content to enhance wear resistance, while stainless steel generally has a higher chromium content, exceeding 12%, primarily to utilize its corrosion resistance. Compared to ordinary bearings, stainless steel bearings not only have a significant advantage in material composition but also require much stricter manufacturing processes and precision control.
The main difference between stainless steel bearings and ordinary bearings lies in their corrosion resistance; other aspects are similar.
If the operating environment is acidic or corrosive, it is recommended to choose stainless steel bearings, as their service life will definitely be superior to that of ordinary bearings.
