Stainless Steel Fabrication
Stainless steel has a very high versatility rate which lends itself to various fabricating techniques. Stainless steel is fairly high in strength and hardening rates, but it is still malleable enough to allow its fabrication process to include bending, folding, machining, welding, deep draw and spinning.
Almost any type of stainless steel can be welded. There are just different degrees of efficiency that depend upon the grade of the stainless steel.
The following are different categories of stainless steel:
- Austenitic – most grades are well-suited for welding purposes.
- Martensitic – good options for welding, but may be prone to cracking.
- Ferritic – most grades of this type are less suitable for welding.
- Duplex – works well for low thermal expansion and is efficient for welding.
Machining Stainless Steel
Machining during the stainless steel fabrication process raises the concern of chipping. This concern causes the method to become quite complex. Therefore, there are several things that we can do during the stainless steel fabrication process in order to help lessen the possibility of this from occurring.
These may be:
- Application of coolant or lubricants to our equipment.
- Use of large tools in order to dissipate heat.
- Light cuts and constant feeds are maintained.
- Use of chip breakers to deflect debris.
- A machine tool is selected in order to reduce the amount of vibrations.
- The cutting edge is kept sharp at all times.
