Stainless steel material comparison

When the galvanized steel is painted, how can we avoid the coating falling off?

In the actual construction process, many customers in the galvanized steel since the painting, often produce the phenomenon of paint layer off, today, we around this phenomenon, discuss together, "galvanized steel how to paint, in order to avoid the paint layer off".

First of all, the surface properties of galvanized steel have changed after being treated by galvanized process. Because the zinc layer is smooth, most of the paint can not adhere to it, which is easy to fall off and can not play the role of anti-corrosion protection.

Therefore, although galvanized has certain anti-corrosion effect, but in harsh environment, it is necessary to use paint coating.

Galvanized steel spraying paint, should choose special epoxy primer, this paint is dedicated to galvanized substrate coating, has very good adhesion, ensure that the paint film does not fall off, excellent anti-corrosion.

Special epoxy primer main features:

1, can be used for galvanized iron plate, stainless steel, aluminum plate, cast iron, carbon steel and other substrates, adhesion to, do not fall off, do not drop paint

2. The substrate is free from grinding without sandblasting, saving labor and material costs. The solvent can be used to scrub the surface to remove the oil

3, salt spray resistance time up to 1000h, excellent corrosion resistance

4, can match fluorocarbon, polyurethane, epoxy and other finish paint

5, the paint has solvent and water-based environmental protection

In the case of coating galvanized steel, there are no special requirements, the normal brush or spraying process can be used.

What are the differences between 304 and 316 stainless steel

Hello, friends

Recently, in the process of receiving customers, we have found that many of our friends are still unclear about the concepts of 304 stainless Steel and 316 stainless Steel. Today, Jinan Suorong Steel Group will give you a detailed interpretation. As food-grade materials, What are the differences between 304 and 316 stainless steel?

1. Different brands

Among 304 and 316, 304L and 316L are extended respectively, and their respective brands are as follows:

304 is 06Cr19Ni10, 304L is 00Cr19Ni10;

The 316 is 0Cr17Ni12Mo2 and the 316L is 00Cr17Ni14Mo2.

2, corrosion resistance is different

316 stainless steel is 304 stainless steel on the basis of corrosion resistance, add some molybdenum element, produced by the stainless steel. In various types of water quality (distilled water, drinking water, river water, boiler water, etc.), 304 stainless steel and 316 stainless steel corrosion resistance is almost the same, but when the content of chloride ions in the medium is very high, 316 stainless steel is more suitable.

3. Different fields of application

Although both are food grade materials, they are used in different fields, such as 316 stainless steel, which has good corrosion resistance and is widely used in the field of medical devices.

And 304 stainless steel is widely used in kitchen, tableware and other fields, a wide range of use, stainless steel table top, stir-fry pot, stainless steel tableware, are used 304.

4. Price.

Due to the added molybdenum and nickel elements, 316 stainless steel is more expensive than 304 stainless steel. 316 stainless steel, the common market price is more than 20 thousand yuan a ton, and 304 stainless steel is 15 ~ 20 thousand yuan a ton, so the cost of 316 is higher.

Finally, Jinan Suorong Steel Group would like to propose that when choosing 304 and 316 stainless steel products, you should decide according to your own use environment, and avoid blind consumption and unnecessary expenditure.

Stainless steel roll in life is mainly used in what aspects?

stainless steel coil has become an important industrial raw material and construction material since its birth because of its strong corrosion and rust resistance. Today, Jinan Suorong Trade Co., Ltd simply introduces, stainless steel coil in life is often used in what aspects.

1. The automobile industry

stainless steel coil is not only strong in corrosion resistance, but also relatively light weight, therefore, it is widely used in the automobile manufacturing industry, such as the automobile shell needs a large number of stainless steel coil, according to statistics, A car needs about 10-40 kilograms of stainless steel coil, in addition, stainless steel coil in high-speed rail, subway and other aspects are also widely used.

2. Water storage and transportation industry

Drinking water is easily contaminated in the process of storage and transportation, and the storage and transportation equipment made of stainless steel coil as the base material is recognized as the most hygienic, safe and efficient water industry equipment in the world. With the increasing demand for sanitary safety of domestic water, stainless steel coil will become an important raw material of water storage and transportation equipment in the future.

3. Construction industry

stainless steel material is one of the earliest architectural materials used in the field of architecture. Decorative panels of exterior walls of buildings and interior wall decoration are generally made of stainless steel coil. They are not only durable, but also very beautiful. In addition, with the continuous development of interior decoration, stainless steel coil is more and more used in the home improvement industry as decorative materials.

In addition to the above several main areas, stainless steel in life there are many applications.
