The difference between stainless steel screws and carbon steel screws?
The difference between stainless steel screws and carbon steel screws?
First of all, we need to know what are the common stainless steel and carbon steel materials: stainless steel is divided into martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel and For precipitation hardening stainless steel, carbon steel materials are generally divided into carbon content: low carbon steel, medium carbon steel and high carbon steel.
To distinguish from the metal composition, carbon steel is steel without adding other metal elements, while stainless steel is for rust prevention, so steel with high alloy content is added.
And because of this, the hardness of carbon steel will be greater than that of stainless steel, and the strength is higher, but it is easy to rust, and the rust resistance of stainless steel will be better than carbon steel. As the saying goes, you get what you pay for. The price will be higher than that of carbon steel, so the price of stainless steel screws will be higher than that of carbon steel screws.
The performance of stainless steel and carbon steel is different, which determines their use environment. Because stainless steel screws have much higher corrosion resistance than carbon steel screws, they are often used in the medical and food industries to come into contact with external substances. Carbon steel has poor corrosion resistance, and is generally used in an environment with fewer contacts or inside the machine to avoid rapid corrosion.
Everyone should not blindly think that stainless steel screws are better than carbon steel screws because stainless steel is expensive. In fact, each material has its own advantages and disadvantages. We only need to use its strengths to use the screws in the most suitable environment.
