What are the types of stainless steel products? Introduction of stainless steel building materials

You must have seen or used a lot of stainless steel products in your daily life! Many bowls, pots and pans we usually use are made of stainless steel. This material is chosen because it is not easy to rust and has a beautiful appearance. However, there are many kinds of stainless steel products, not only simple household appliances, but also in other fields. So do you know what types of stainless steel products are? Today, Xiaobian will introduce it in detail for everyone!

what are the types of stainless steel products?

first, the first category of stainless steel products: plates

There are many types of stainless steel plates with different properties, which have gradually formed several categories in the development process. According to the organization structure, it can be divided into four categories: martensite stainless steel plate (including precipitation hardening stainless steel plate), ferrite stainless steel plate, austenite stainless steel plate and austenite plus ferrite duplex stainless steel plate. According to the main chemical composition of steel plate or some characteristic elements in steel plate, it can be classified into chromium stainless steel plate, chromium nickel stainless steel plate, chromium nickel molybdenum stainless steel plate, low carbon stainless steel plate, high molybdenum stainless steel plate and high purity stainless steel plate. Steel plates are classified into nitric acid-resistant stainless steel plates, sulfuric acid-resistant stainless steel plates, pitting corrosion-resistant stainless steel plates, stress corrosion-resistant stainless steel plates and high-strength stainless steel plates according to their performance characteristics and uses. According to the functional characteristics of steel plates, they are classified into low-temperature stainless steel plates, nonmagnetic stainless steel plates, free-cutting stainless steel plates and superplastic stainless steel plates. At present, the commonly used classification method is to classify steel plates according to their organizational structure characteristics and chemical composition characteristics, as well as their combination.

Second, the second category of stainless steel products: pipes

Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural steel pipes, alloy steel pipes, bearing steel tube, stainless steel pipes and bimetallic composite pipes, plated and coated pipes to save precious metals and meet special requirements. There are many kinds of stainless steel pipes with different uses, different technical requirements and different production methods. At present, the steel pipes produced range from .1 to 4,5 mm in outer diameter and .1 to 25 mm in wall thickness. In order to distinguish its characteristics, steel pipes are usually classified as follows.

(1) mode of production? Stainless steel pipes can be divided into seamless pipes and welded pipes according to production methods, and seamless steel pipes can be divided into hot tube, cold-drawn pipes, cold-drawn pipes and extruded pipes, etc. Cold-drawn and cold-rolled pipes are the secondary processing of steel pipes; Welded pipes are divided into straight welded pipes and spiral welded pipes.

(2) section shape? Stainless steel pipes can be divided into round pipes and special-shaped pipes according to their cross-sectional shapes. Special-shaped tubes include rectangular tubes, rhombic tubes, elliptical tubes, hexagonal tubes, octagonal tubes and tubes with asymmetric sections. Special-shaped pipes are widely used in various structural parts, tools and mechanical parts. Compared with circular tubes, special-shaped tubes generally have larger moment of inertia and section modulus, and greater bending and torsion resistance, which can greatly reduce structural weight and save steel. Stainless steel pipes can be divided into equal-section pipes and variable-section pipes according to the shape of longitudinal section. Variable cross-section tubes include tapered tubes, stepped tubes and periodic cross-section tubes.

(3) what is the shape of the pipe end? Stainless steel pipe can be divided into smooth pipe and turning wire pipe (with screw pipe) according to the state of the pipe end. Turning wire pipes can be divided into ordinary turning wire pipes (low-pressure pipes for conveying water and gas, etc., which are connected by common cylindrical or conical pipes with threads) and special threaded pipes (pipes for petroleum and geological drilling, which are connected by special threads for important turning wire pipes). For some special pipes, in order to make up for the influence of threads on the strength of pipe ends, the pipe ends are usually thickened (inside thickening, outside thickening or inside and outside thickening) before turning wire.

(4) classification of use? According to the purpose, it can be divided into oil well pipes (casing, tubing and drill pipe, etc.), pipeline pipes, boiler tubes, mechanical structure pipes, hydraulic prop pipes, gas cylinder pipes, geological pipes, chemical pipes (high-pressure fertilizer pipes, petroleum cracking pipes) and ship pipes.

third, the third category of stainless steel products: profiles

profiles are the most extensive processing fields, and there are countless products. Here are the most common ones: stainless steel tableware, stainless steel doors, stainless steel coffee tables, stainless steel chairs, stainless steel cabinets, stainless steel display stands, stainless steel stair handrails, stainless steel security window, stainless steel screens in hotels, stainless steel sculptures in parks, stainless steel water tanks, stainless steel nets, stainless steel locks, stainless steel screws, stainless steel reaction kettles and even stainless steel soap.

well, the classification of stainless steel products is basically these kinds. I believe that these stainless steel products introduced by the above small series are not uncommon. Stainless steel is loved by people for its many advantages. I believe that many things can be replaced by stainless steel in the future development, so that we can enjoy the convenience brought by stainless steel. Of course, if you have time, you can also learn about the classification of other materials.
