The origin and characteristics of stainless steel

Stainless steel, also known as stainless acid-resistant steel and water-copper iron. Stainless steel is mainly composed of iron, chromium, nickel and other elements. The proportions of these elements determine the properties of stainless steel. High-quality stainless steel has the characteristics of corrosion resistance, oxidation resistance and high strength. Among them, the most important metal element that determines the rust-proof ability of stainless steel is chromium. In this blog post, we will discuss the origin and related characteristics of stainless steel, and introduce you to the characteristics and application fields of some stainless steel products.

Origin and development

The history of stainless steel can be traced back to the late 19th century. Initially, stainless steel was studied as a wear-resistant alloy material for military firearms. However, due to technical limitations and lack of funds at the time, Brearley’s team accidentally discovered an alloy steel that was not easy to wear and corrosion-resistant during the experiment. After further experimental confirmation, this alloy steel was named chromium alloy and began to be used. Used in tableware and other fields. Brearley is also known as the “Father of Stainless Steel” for his contributions to the field of stainless steel. Since then, stainless steel has gradually become an important industrial material and has been widely used in different fields.

Characteristics and applications of stainless steel products

1. Stainless steel sheet

Stainless steel plate is a metal material with high corrosion resistance and aesthetics. It is widely used in construction, home, automobile and other fields. According to different compositions and characteristics, stainless steel plates can be divided into many types, such as 304L stainless steel sheets, 316L stainless steel plates, 8K stainless steel sheets, etc.

304L stainless steel plate is a stainless steel material with excellent corrosion resistance and processing performance. It is widely used in petroleum, chemical industry, food, medical equipment and other fields. It contains 18% chromium (Cr) and 8% nickel (Ni), has good corrosion resistance, and can remain stable in various corrosive environments. In addition, 304L stainless steel plate also has excellent low-temperature toughness and can maintain strength and stability in low-temperature environments.

316L stainless steel plate is slightly better than 304L stainless steel plate in terms of corrosion resistance, especially in the marine environment and chemical industry.

2. Stainless steel coil

The manufacturing process of stainless steel coils mainly includes hot rolling, cold rolling, annealing, etc., which can be selected according to actual needs. According to different compositions and characteristics, stainless steel coils can be divided into many types, such as 304 stainless steel coils, 316 stainless steel coils, etc. These types of stainless steel coils have different characteristics in terms of strength, corrosion resistance and aesthetics, and can be selected according to actual needs.

316L and 304 stainless steel coils are important categories of stainless steel products and have a wide range of applications. Both stainless steel coils contain chromium and nickel elements and have good corrosion resistance and processability. However, their composition and properties differ slightly.

316L stainless steel coil contains molybdenum element, so it has better corrosion resistance. In addition, 316L stainless steel coils also have high strength and excellent low-temperature toughness, and can maintain stable performance in extreme environments. Therefore, 316L stainless steel coils are widely used in marine engineering, chemical equipment and other fields.

304 stainless steel coil is a popular stainless steel material with excellent corrosion resistance and processing performance. It is widely used in food, medical equipment, electronic equipment and other fields. Compared with 316L stainless steel coils, 304 stainless steel coils are lower in cost and therefore are widely used in some situations that do not require particularly high corrosion resistance.

3. Color-coated stainless steel

Color-coated stainless steel is a specially treated stainless steel material with a colored coating on the surface to increase its aesthetics. This coating can be the original color of stainless steel or other colors, such as gold, silver, etc. Its production process mainly includes polishing, coating, curing, etc.

Color-coated stainless steel has excellent corrosion resistance and processing performance, and the surface coating also has good wear resistance and scratch resistance. Therefore, colored stainless steel is widely used in various decorative fields, such as architectural decoration, furniture decoration, etc. In addition, painted stainless steel can also be used to make various high-end tableware and kitchen utensils, such as coffee cups, spatulas, etc.

In short, stainless steel is a remarkable material that has brought revolutionary changes to various industries. Its origins can be traced back to Harry Brearley’s accidental discovery, and since then its unique properties have made it a popular choice in modern society. Corrosion resistance, strength and durability, hygienic properties and aesthetics are some of the key features for its widespread use. With the continuous advancement of technology, stainless steel products have been widely used in various fields.
