Why is 201 stainless steel welded pipe expensive?

201 stainless steel welded pipe, why the price will deviate? In fact, the price of 201 stainless steel welded pipe is the difference of 201 stainless steel, which is divided into medium belt and refining furnace.

304 stainless steel strip has good corrosion resistance, heat resistance and mechanical properties. Corrosion resistance in the atmosphere, if it is an industrial atmosphere or heavily polluted area, it needs to be cleaned in time to avoid corrosion. Suitable for food processing, storage and transportation. Has good processability and weldability. Plate heat exchangers, bellows, household goods, building materials, chemical, food industry, etc.

1. IF furnace material is made from recycled waste, a sub-type furnace process. The material of the recycled material is non-uniform, which leads to poor material stability;

2. The refining furnace material is divided into J1 and J3, and J3 is cheaper than J1 steel strip. Stainless steel plate 304

What is the difference between the steel straps in J1 and J3?

The two appearances are not big, mainly in the chemical composition, the key to the price is the content of "carbon", "chromium" and "copper". Stainless steel plate 304

1. Differences in carbon content:

J3 has a higher carbon content than J1. The carbon content of 201 stainless steel pipes in the national standard should not be higher than 0.1%, which is due to the high carbon content to reduce the corrosion resistance of the steel.

2. Copper Differences:

J1 contains 0 amount of copper. 7%-0.8%, the higher the copper, the higher the amount of copper. The higher the tensile performance, the higher the rust resistance, and the better the brightness of the corresponding 201 stainless steel tube.

3. Differences between chromium content:

The chromium content in the national standard is 13%-15%. Chromium can significantly improve the corrosion resistance of steel. Carbon element is more easily oxidized, and chromium is the role of anti-oxidation and corrosion resistance. The higher the chromium, the higher the chromium, the stronger the protective role, so the high-chromium and low-carbon refining furnace J1 is higher than the J3 material.

Price is a commodity advantage in non-express form, we should pay more attention to product quality while seeking cost. Adhere to quality as the core.
