Stainless steel is an excellent medium for fabrication. A lot of fabrication facilities have used it before, but few are experts in stainless steel fabrication.
A perk of working with stainless steel is that it is easier than some other materials at being fabricated by way of the common fabrication techniques, usually it is a better choice than the commonly known carbon steels. Stainless steel can be folded, bent, cold and hot forged, deep drawn, spun and roll formed. Because stainless steel is extremely durable and hardens quickly, fabrication and machining can need more force than what is typically applied to carbon steels. This is why that more powerful machines and tolls may be needed.
stainless steel machining is the general phrase used to characterize the machining functioning of a material by a cutting tool. Considering stainless steel has distinctive characteristics than carbon steels, different techniques are needed. The biggest reason for the difference is that stainless steels are rather tough and it has the inclination to seize and gall.
Regarding stainless steel machining, it can be a hard substance to machine. Stainless steel is an ideal material since it is very corrosion resistant. A few basic rules for stainless steel machining include:
- The machining tool must be sturdy, powerful, and be buffered from vibrations.
- It’s important to keep the cutting edge sharp at all times as dull tools can damage the surface.
- When possible, try to keep the cuts light to reduce hardening from the riding of the surface.
- Proper clearance should be provided to keep the tools from touching the project.
- Larger tools are preferred to help to cut down on the heat.
- To reduce chips from interfering with the work, use chip breakers or chip curlers.
- To restrict the tool from riding the work, use a constant feed.
- Proper use of coolants and lubricants are necessary, it is important to clean and remove the cutting fluid and degrease the work piece and work area. This can be done with conventional degreasing solutions. If the work piece has been put under extreme heat or when maximum corrosion resistance is needed, it may be appropriate to passivate or pickle and passivate. Passivation is a process that is used to make a surface passive, in other words a surface film is made that causes the surface to lose its chemical reactivity. Pickle and passivate is a two step process used to create a surface that is immune to corrosion. Pickling is a form of chemical descaling done to remove scale and the passivation is done to make the surface more passive and corrosion resistant.
