SS316L SS202 316 Stainless Steel Pipe Astm A269 Tp316l Spiral Pipe
Changes martensite back to austenite
The stainless steel we commonly use in our stainless casters is 304. After cold work (the process of stamping, forming, surface polishing, etc) a stainless caster usually becomes magnetic in the worked areas. These areas are relatively prone to rust in a corrosive environment. If it is necessary, annealing is the most effective way to restore non-magnetic property and enhance corrosion resistance. Actually it changes martensite back to austenite. In this process the stainless product is heated to 1800F – 2100F and cooled down slowly. If the temperature is not high enough the corrosion resistance of the stainless will be reduced. This process increases cost a lot. The passivation process washes away free particles and forms a passive coating on the stainless surface. This process is what we do for only stainless caster model G15. It is a relatively economic way to enhance corrosion resistance, but it is not meant to completely restore non-magnetic property.
How To: Remove Scratches from Stainless Steel
From sinks to appliances, counters to cabinet hardware, stainless steel remains a popular kitchen trend, favored for its sleek look and durability. Yet, sturdy as it is, stainless can acquire unsightly scratches in the course of everyday activity. Fortunately, it’s totally possible to minimize these signs of wear and tear, even successfully remove scratches from stainless steel altogether.
