What are the types of stainless steel products?

First, the first type of stainless steel products: plate

There are many kinds of stainless steel plates with different properties, and it has gradually formed several categories in the development process. According to the structure, it is divided into four categories: Martensitic stainless steel plate (including precipitation hardening stainless steel plate), ferritic stainless steel plate, austenitic stainless steel plate and austenitic ferrite duplex stainless steel plate. According to the main chemical composition of the steel plate or some characteristic elements in the steel plate to classify, divided into chromium stainless steel plate, chromium nickel stainless steel plate, chromium nickel molybdenum stainless steel plate and low carbon stainless steel plate, high molybdenum stainless steel plate, high purity stainless steel plate and so on. According to the performance characteristics and uses of the steel plate, it is divided into nitric acid resistant stainless steel plate, sulfuric acid resistant stainless steel plate, pitting stainless steel plate, stress corrosion resistant stainless steel plate, high strength stainless steel plate and so on. According to the functional characteristics of the steel plate, it is divided into low temperature stainless steel plate, non-magnetic stainless steel plate, easy cutting stainless steel plate, super plastic stainless steel plate and so on. The commonly used classification method is classified according to the structural characteristics of the steel plate and the chemical composition characteristics of the steel plate and the combination of the two methods.

Second, the second largest type of stainless steel products: pipes

Stainless steel pipes are divided into ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes and bimetal composite pipes, coatings and coated pipes to save precious metals and meet special requirements. There are many kinds of stainless steel pipes, different uses, different technical requirements, and different production methods. The current production of steel pipe diameter range 0.1-4500mm, wall thickness range 0.01 ~ 250mm. In order to distinguish its characteristics, the steel pipe is usually classified according to the following method.

(1) Production method Stainless steel pipe according to the production method is divided into seamless pipe and welded pipe two categories, seamless steel pipe can be divided into hot rolled pipe, cold rolled pipe, cold drawn pipe and extruded pipe, cold drawing, cold rolling is the secondary processing of steel pipe; The welded pipe is divided into straight seam welded pipe and spiral welded pipe.

(2) Section shape Stainless steel pipe according to the cross-section shape can be divided into round pipe and shaped pipe. The special-shaped pipe has rectangular pipe, diamond pipe, oval pipe, hexagonal pipe, eight pipe and a variety of cross-section asymmetric pipe. Shaped tubes are widely used in various structural parts, tools and mechanical parts. Compared with the round tube, the shaped tube generally has a larger moment of inertia and section modulus, and has a larger bending and torsional resistance, which can greatly reduce the weight of the structure and save steel. Stainless steel pipe according to the profile shape can be divided into equal section pipe and variable section pipe. The variable section pipe has conical pipe, stepped pipe and periodic section pipe.

(3) Pipe end shape Stainless steel pipe according to the pipe end state can be divided into light pipe and wire pipe (with rebar steel pipe). Wire pipe can also be divided into ordinary wire pipe (conveying water, gas and other low pressure pipe, using ordinary cylindrical or conical pipe thread connection) and special thread pipe (oil, geological drilling pipe, for important wire pipe, using special thread connection), for some special pipe, in order to make up for the impact of thread on the strength of the pipe end, Tube end thickening (internal thickening, external thickening or internal and external thickening) is usually carried out before wire drawing.

(4) Use classification According to use can be divided into oil well pipe (casing, tubing and drill pipe, etc.), pipeline pipe, boiler pipe, mechanical structure pipe, hydraulic support pipe, gas cylinder pipe, geological pipe, chemical pipe (high-pressure fertilizer pipe, oil cracking pipe) and ship pipe.

Third, the third largest type of stainless steel products: profiles

Profiles are the most extensive processing field, and there are countless products. Here are the most common: stainless steel tableware, stainless steel doors, stainless steel coffee tables, stainless steel chairs, stainless steel cabinets, stainless steel display shelves, stainless steel stair railings, stainless steel anti-theft Windows, stainless steel hotel screens, park stainless steel sculptures, stainless steel water tanks, stainless steel nets, stainless steel locks, stainless steel screws, stainless steel reactors, even stainless steel soap and so on.
