10 Trustworthy Chinese Stainless Steel Manufacturers

WANJIAHONG > news > 10 Trustworthy Chinese Stainless Steel Manufacturers


Stainless steel is one of the most popular materials, partly taking place of normal steel and iron. Moreover, the application of stainless steel has achieved a great result in many areas. Under this circumstance, more and more people put their eyes on the stainless steel industry. As the largest manufacturer of stainless steel , China is attracting people’s attention , so do the Chinese stainless steel manufacturers. Through this article, we will share some information about Stainless steel. Besides, you can have a basic knowledge of Chinese stainless steel manufacturers and the Chinese market.

Main types of stainless steel

304 stainless steel

As a kind of widely used steel, 304 stainless steel has good corrosion resistance, heat resistance, stable strength in low temperature, excellent thermal processability. Without heat treatment hardening phenomenon and magnetism, the application temperature ranges from minus 193 degrees to 800 degrees.

Application: tableware, kitchenware, water heater, boiler, auto parts, medical equipment, food machinery, wine storage, pressure vessel (chemical machinery, chemical equipment).

304L Stainless Steel

As one kind of 304 steel, 304L has a low carbon content. In normal conditions, its corrosion resistance is the same as that of 304 steel. However, after welding and stress elimination, it can maintain good corrosion resistance even without heat treatment. People normally use 304L steel under 400 degrees.

Application: petrochemical industry, building materials.

321 Stainless Steel

People add Ti element into 304 steel to create 321 steel, which is able to prevent intergranular corrosion. 321 steel is fit to the temperature from 430 to 900 degrees. For the addition of Ti element, 321 steel is not suitable for the food processing equipment.

Purpose: automobile exhaust, heat exchanger, container, and other products without heat treatment after welding

309S/310S Stainless Steel

corrosion resistance

When it comes to the 309S/310S steel, the content of nickel and chromium are relatively high. At the same time, the content of the Si element is increased, so that it has high-temperature resistance and corrosion resistance. Among them, 309S can withstand repeated heating below 980 degrees. The application temperatures of 310S can reach 1200 degrees, and the continuous service temperature can up to 1150 degrees.

Application: electric equipment with high temperature, key components of dry equipment, furnace materials, aviation, petrochemical, electric power, etc.

200 Stainless Steel

The 200 series is similar to the 304 in economic price.

In terms of fatigue resistance, 304 steel is better than 201 steel. But 201 steel is greater than 304 steel in hardness.

Application: food processing utensils, kitchen equipment, food processing equipment, filters, milk cans, washing machine accessories, water heaters, steel furniture, architectural upholstery, decoration.

Overview of 304 stainless steel sheet

201 stainless steel sheet | A detailed introduction

Why does stainless steel rust?

Maybe you will be curious about the heading? How ridiculous it is? That’s why I put this question in this article. This part of the content will provide the reasons and solutions to it.

There is a layer of stable chromium oxide film, which is thin but strong, serving as a protective film to prevent the oxygen atoms from infiltration and oxidation. This protective film is the reason why stainless steel can resist corrosion.

So it’s understandable that why does stainless steel rust. If the film is destroyed for some reason. Air or liquid neutral oxygen atoms will keep infiltrating, which forms iron oxide. Finally, the metal surface can be corroded.

reagent test

After we know the principle of such circumstance.

Three main factors are affecting stainless steel corrosion:

1. The content of alloying elements

generally speaking, about 10.5% of chromium can enable steel not easy to rust. The higher the content of chromium and nickel, the better the corrosion resistance. Take 304 stainless steel as an example. With 8-10% of nickel and 18-20% of chromium, it would not rust generally.

2. The external environment

A dry and ventilated environment is not easy to rust. Stainless steel is easy to rust in an environment with high air humidity, long-time cloudy and rainy weather, or an environment with large acidity and alkalinity.

3. The smelting process

The smelting process of the production enterprise will also affect the corrosion resistance of stainless steel. Large-scale stainless steel factory with Top-class Smelting technology, advanced equipment, the advanced process of large stainless steel factory can do better in the control of alloy elements, the removal of impurities, billet cooling temperature control, so the product quality is stable and reliable. With good inherent quality, the products are not easy to rust. On the contrary, a manufacturer with backward equipment, the backward process can not fully remove impurities, so the products will inevitably rust.

The above circumstances can destroy the protective film on the surface of stainless steel, leading to corrosion. Therefore, to avoid such circumstances, We provide three suggestions here.

1. Clean the surface regularly

You have better regularly clean and scrub the surface of stainless steel, remove attachments and eliminate the external factors that can cause corrosion.

When cleaning your stainless steel, be careful and use a non-abrasive tool. Soft cloths and plastic wipes will not damage the stainless steel surface. Of course, you can also use steel wool to clean it, but you should remember to wipe the surface in accordance with the manufacturer’s polishing mark. If the texture is not clear, then you have to be careful and wipe it with a soft cloth or plastic pad


2. Choose proper types of stainless steel

It would be better to choose 316 stainless steel in the seaside area because of the strong resistance to the corrosion of seawater 316 stainless steel has.

3. Quality of stainless steel

The chemical composition of some stainless steel pipes on the market can not meet the national standards and the material requirements of 304.

As the second and third point shown above, we need to carefully choose the products of reputable manufacturers

As to the manufacturers with reputation, Chinese stainless steel manufacturers worth our attention.

Many years ago, people thought that the products from China through affordable, the quality was lower than the international standard.

Nowadays, products from China can provide both high quality and acceptable prices. It is totally different from the condition before.

Development of Chinese stainless steel market


China produced 524,000 tons of stainless steel, accounting for only 2.8% of the world’s total stainless steel production of 18.43 million tons.


China produced 23.46 million tons of stainless steel, accounting for 55.6 percent of the world’s total stainless steel production of 42.2 million tons.

From January to June 2016

China’s stainless steel crude steel output was 12.38 million tons, up 8.6% year on year; During the same period, the export of stainless steel reached 1.8412 million tons, up 12.6% year on year. Imports of stainless steel in the same period were 329,500 tons, down 11.5% lower than that in 2015.


The Chinese stainless steel industry experienced a leaping development, From 2010, China’s export has greater than imports in the stainless steel industry. No matter the quantity, quality, or varieties, China has become a worldwide leading force for the development of the stainless steel industry.
