Austenitic stainless steel strip refers to the stainless steel strip with an austenitic structure at room temperature. The austenitic stainless steel strip is non-magnetic and has high toughness and plasticity, but the strength is low, cannot be strengthened through phase transformation, can only be strengthened through cold working. What is the austenitic stainless steel strip? We will cover this in the following sections.

Here is the content list:

  1. Characteristics of austenitic stainless steel strip

  2. The production process of austenitic stainless steel strip

  3. The development direction of austenitic stainless steel strip

Characteristics of austenitic stainless steel strip

Austenitic stainless steel strip in addition to oxidation resistance acid medium corrosion, if it contains Mo, Cu and other elements can also resist sulfuric acid, phosphoric acid, formic acid, acetic acid, urea, and other corrosion. If the carbon content of the steel strip is less than 0.03% or contains Ti and Ni. The intergranular corrosion resistance of the steel strip can be significantly improved. High silicon austenitic stainless steels have good corrosion resistance to concentrated nitric acid. Austenitic stainless steels have been widely used in all walks of life because of their comprehensive and good properties.

The production process of austenitic stainless steel strips

The production process of austenitic stainless steel strip has good performance, especially that of chromium-nickel austenitic stainless steel, all kinds of plates, pipes, strips, wires, bars, forgings, and castings can be produced smoothly by using the conventional means of producing special steel. Due to the high content of alloying elements (especially chromium) and low carbon content, arc furnace plus argon oxygen decarburization (AOD) or vacuum deoxidization decarburization (VOD) method for mass production of this kind of stainless steel, for high-grade small-batch products can be used a vacuum or non-vacuum non-induction furnace smelting, when necessary, electro slag melting.

Austenitic stainless steel strip production is widely used in advanced technology, such as the refining rate outside the furnace reaches more than 95%, the continuous casting ratio exceeds 80%, and high-speed rolling mills and fine and fast forging machines are widely promoted. Especially in the smelting and processing process to achieve computer control, to ensure product quality and performance of reliable and stable.

The development direction of austenitic stainless steel strip

The future development direction of austenitic stainless steel strip is as follows:

(1) the steel is very low carbonization (carbon <=0.02%) and high purification (as impurity elements such as sulfur, phosphorus, silicon, manganese content are very low).

(2) Development of steel grades for special purposes. Such as high molybdenum steel for hot seawater, high corrosion resistance, and high strength high nitrogen steel (nitrogen content up to 0.4% ~ 0.6% or even 0.8% ~ 1.0%), stainless steel functional materials (memory materials, hydrogen storage materials, etc.).

(3) New process development. Stainless steel composite materials, amorphous stainless steel, etc.

It is the responsibility of each manufacturer to produce the standard Austenitic stainless steel strip, so as to ensure the safe and healthy development of the stainless steel strip market. Foshan Taiyuda Iron and Steel Group Co., Ltd. on the Austenitic stainless steel strip in the factory before many tests, the quality pass rate is guaranteed. If you are in the Austenitic stainless steel strip business, you can consider our product’s cost performance.
