R&R Stainless Steel introduces you to 20 technical terms related to stainless steel

The 20 technical terms related to stainless steel are summarized as follows:

SUS (Steel Use Stainless): The international code abbreviation for stainless steel materials, widely used in international trade to identify stainless steel products.

304/316L: Common grades of stainless steel materials, respectively containing 18% and 16% or more chromium and 8% and 10% or more nickel, with good corrosion resistance.

Pickling: A surface treatment process for stainless steel that removes surface oxide and chromium compounds formed during welding through chemical methods to improve surface smoothness.

Polishing: A stainless steel surface treatment process that uses mechanical or chemical methods to make the surface smooth and shiny, enhancing the product's aesthetics and corrosion resistance.

Sandblasting: A stainless steel surface treatment process that uses high-pressure airflow to spray abrasive onto the surface of stainless steel, creating a uniform sanding effect. It is commonly used to enhance surface texture or remove surface contaminants.

Electropolishing: An advanced surface treatment process for stainless steel that removes surface oxide through electrolysis, resulting in a smoother and brighter surface while improving corrosion resistance.

Passivation: A surface treatment process for stainless steel that forms a dense oxide protective film through chemical methods to improve the corrosion resistance of stainless steel.

Drawing: A stainless steel processing technique that uses mechanical or chemical methods to create a silky effect on the surface, enhancing the aesthetic and tactile feel of the product.

Embossing: A stainless steel processing technique that creates raised or recessed patterns on the surface, commonly used in the manufacture of decorative stainless steel products.

Austenitic Stainless Steel: Stainless steel mainly composed of austenite, with good corrosion resistance, plasticity, and toughness, and is one of the most widely used types of stainless steel.

Ferritic Stainless Steel: A stainless steel with low chromium content or no nickel added, and a structure of ferrite or ferrite+a small amount of austenite, which has high stress corrosion resistance.

Hot Rolling: A stainless steel material processing technology that heats steel billets to high temperatures and forms the desired shape and size through rolling processing.

Cold Rolling: A stainless steel material processing technique that optimizes the mechanical properties and surface quality of materials through rolling at room temperature.

Cold Drawing: The process of forming the desired shape and size of stainless steel material through stretching at room temperature.

Welding: The process of firmly connecting two or more stainless steel materials together by heat or pressure, widely used in the manufacturing and installation of stainless steel products.

Electroplating: The process of using electrochemical principles to deposit a layer of metal or non-metal coating on the surface of stainless steel material to enhance its surface performance or aesthetics.

Dimension: The length, width, and height indicators of stainless steel products are important parameters for product quality and specifications.

Thickness: The thickness index of stainless steel products has a significant impact on their performance and service life.

Tolerance: The allowable range of deviation between the size and shape of stainless steel products and their nominal values, which is an important indicator for product quality control.

Corrosion Resistance: The ability of stainless steel materials to resist corrosion from corrosive media, and is one of the important indicators for evaluating the performance of stainless steel.

The above terms cover the material types, surface treatment processes, processing techniques, dimensional specifications, and performance characteristics of stainless steel, and are the basis for understanding and applying stainless steel technology.
