Stainless steel screws advertising in our daily lives mortal mainly used to install some outdoor billboards, and many other factors profiles, structure, size, location of billboards is an important factor in the decision to use what kind of profiles installed stainless steel screws advertising, which Why stainless steel screws profiles have what type? Here let us take a look at it.
Its stainless steel screws advertising there are three main sections:
First, the austenitic stainless
The most basic element of austenitic stainless steel alloys of chromium and nickel, typically containing grade of about 18% chromium, nickel-chromium containing about 8% of a nickel austenitic stainless steel, commonly referred to as 18-8 stainless steel. The ratio of the elements chromium and nickel to ensure that the structure of the steel is substantially stable austenite.
Second, ferritic stainless steel
430 ordinary chrome steel, and its corrosion resistance and heat resistance than Type 410 is good, there are magnetic, but it can not be heat strengthened, while suitable for higher corrosion resistance and heat resistance, and strength requirements of the general stainless steel screws.
Third, martensitic stainless steel
410 and 416 can be heat strengthened, hardness 35 ~ 45HRC, good machining performance for general purpose corrosion resistant stainless steel screws.
Fourth, some of the principles of selection of stainless steel screws
Choose stainless steel mainly from the following five aspects to consider:
1, the material of the stainless steel screw mechanical properties, specifically strength requirements;
2, the workers do conditions on the material aspects of corrosion resistance requirements;
3, the working temperature of the material heat resistance (high temperature strength, oxidation resistance) requirements;
4, the production process of the material processing performance requirements;
5, other aspects, such as weight, price, purchase, and many other factors must be considered

Stainless steel screws rusty
Stainless steel screws combinations in our daily lives is mainly used in electrical, electronics, machinery and equipment, electronics, shipbuilding, chemicals, water, and so many other industries, and its aim is to make it to the fastening device between product parts and components, but when put into use, through a long period of observation we will find a combination of stainless steel screws rusting phenomenon will occur, which it why would rust? Here let us take a look at it. Many people m
China is expected to diversify operations carried hardware
Contest these jobs are in the onset of furniture hardware changes, followed by improvements in the external environment, the company launched add experience, the quality of its all going. Low-grade furniture hardware company began focusing on quality and corporate culture, collaboration and communication between the companies has become even more frequently, the company about the brand also began to broaden and deepen the depth of excavation into segments consisting of representation fro
LED lights strengths
1, LED streetlights own characteristics - unidirectional light, no light diffusion, ensuring illumination power. 2, LED lights have a common secondary optical plan, the LED street light shines on the desired area lighting to further enhance the power of light to reach the energy-saving intentions. 3, LED light source power has reached 110-130lm / W, and there is still much room for development, the theoretical value of 360lm / W. The high pressure sodium light power is only being added wit
