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.

1. 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).
2. Stainless steel pipe is generally suitable for the welding of thin steel pipe below 6mm,

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.

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

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
