Stainless steel, known for its excellent rust resistance, and its screw products are no exception. However, in addition to rust resistance, stainless steel screws also have other important performance indicators, one of which is the strength rating. Although many people think that high-strength screws are limited to carbon steel materials, stainless steel screws also have excellent strength. In fact, the strength levels of stainless steel screws are real and play a crucial role in several fields
Stainless steel screws, known for its excellent rust resistance, at the same time, its strength level is also a key indicator. In practice, the strength level of stainless steel screws is very important to ensure the safety and stability of the structure. By knowing the strength level of stainless steel screws, we can better select the screw products suitable for specific needs, thus ensuring the smooth completion of the project.
304 stainless steel screw performance
304 stainless steel, also known as stainless acid-resistant steel, its chemical composition includes 0Cr19Ni9(or 0Cr18Ni9), with the excellent quality of austenitic stainless steel. The carbon content of the material is controlled to be less than 0.08%, the manganese content is 2%, the yield point is set at 205MPa, and the tensile strength is at or above 515Mpa. In addition, 304 stainless steel also shows excellent corrosion resistance, which is given by the uniqueness of its nickel content, compared with other types of stainless steel, its corrosion resistance rate is dozens of times higher. On the other hand, the non-standard screw as a tightening tool, its working principle based on the object of the inclined plane circular rotation and friction, through the ingenious use of physics and mathematics principles, gradually tighten the machine parts.
Generally speaking, stainless steel screws usually have a strength rating between 4.8 and 6.8. It is worth noting that stainless steel screws are not suitable for heat treatment processes, that is, they cannot be hardened to improve their strength. Therefore, the strength grade of the stainless steel screw actually reflects the strength level of its wire.
