Grades of commercial stainless steel and sheet metal brackets
It’s time to look at some recently cut stainless steel brackets as this gives me the ideal opportunity to talk about the different grades of commercial stainless steel available. We often find our customers are unsure about the grade of stainless they require and turn to us for advice. Sometimes we find the grade is stated but it may be incorrectly specified which could have an impact on the durability of the final product. Moreover it could effect the final cost of each component through “over specification” when a lower grade stainless would have “done the job” adequately.
Laser cut brackets
Here at V and F Sheet Metal we mainly use three different grades of stainless steel. Grade 430 is the cheapest, lowest grade with good formability and ductility. It displays magnet properties but is not very corrosion resistance. With these properties in mind, its easy to see why its uses lie in decorative trim and domestic situations.
Setting up the press brake
Grade 304 is a mid range versatile and widely used stainless. It contains more chrome and nickel and displays good corrosion resistance. It’s found in outdoor settings, such as sign production where the exposure to water is not a problem.
Grade 316 is a high quality stainless with an addition of molybdenum giving rise to improved resistance to corrosion. This renders it particularly useful in chloride environments and makes it the stainless of choice in marine environments where metal work is constantly under attack from salty water. It is also used in the catering industry and in the production of high quality surgical components.
Trumpf 7036 CNC press brake
The batch of 250 laser cut brackets shown here were made for an outdoor setting using grade 304 stainless. They were folded on one of our Trumpf 7036 CNC controlled press brakes. Obviously the laser cut components are flat to begin with but they need to be curved and this is achieved using a multiple bending technique, all carried out on the press brake. There is no end to the flexibility of these machines when it comes to bending!
