Stainless steel (Stainless Steel) is the abbreviation of stainless acid-resistant steel, and the steel that is resistant to weak corrosive media such as air, steam, water or has stainless steel is called stainless steel; Steel that is resistant to chemical corrosion media (acid, alkali, salt and other chemical erosion) is called acid-resistant steel.

Stainless steel tube has a good surface finish. It can be used as a decorative tube. It can also be processed and used as a heat exchanger tube according to its characteristics of high temperature resistance and rust prevention. But even the best surface has to be used and maintained by the user reasonably.

Stainless steel coil is made from slab, after going to reheating furnace and rolling process, we receive stainless steel hot rolled black coil.Then we have the coil to go through reheating furnace again, then sandblasting and pickling, we get No.1 hot rolled coil in white.After that, we process the coil with rolling and annealing pickling, cold rolled stainless steel coil is produced.

Stainless steel plate industry is developing rapidly. Many stainless steel plate enterprises have been completed and put into operation. The price rise of raw materials has increased the production cost of stainless steel plate. To a certain extent, it intensifies the tight supply and demand of raw materials for stainless steel plate production, such as nickel, chromium and stainless steel plate scrap.

The power supply with vertical external characteristics is adopted, and the positive polarity is adopted in DC (the welding wire is connected to the negative).

1D -- The surface has discontinuous granular shape, also known as fog surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2D - A slightly silvery white colour.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
