One, stainless steel products The first major category: Plate
There are many kinds of stainless steel sheet, different performance, it gradually formed in the development of several major categories. According to the organizational structure of the martensitic stainless steel plate (including precipitation hardening stainless steel plate), ferritic stainless steel plate, austenitic stainless steel plate and austenite and ferrite duplex stainless steel plate, such as the four major categories. According to the main chemical composition of steel plate or some of the characteristics of steel plate classification, divided into chromium stainless steel plate, chromium-nickel stainless steel plate, chromium-nickel-molybdenum stainless steel plate, as well as Low-carbon stainless steel plate, high molybdenum stainless steel plate, high purity stainless steel plate. According to the characteristics and use of steel plate classification, is divided into nitric acid stainless steel plate, sulfuric acid stainless steel plate, pitting corrosion-resistant stainless steel plate, corrosion-resistant stainless steel plate, high-strength stainless steel plate. According to the functional characteristics of steel plate classification, divided into low-temperature stainless steel plate, stainless steel plate, easy to cut stainless steel plate, such as superplastic stainless steel plate. The commonly used classification method is classified according to the structural characteristics of the steel plate and the chemical composition of the steel plate and the combination of the two methods.
II. Stainless Steel Products The second largest category: pipe
Stainless steel pipe According to the material into ordinary carbon steel pipe, high-quality carbon structural steel pipe, alloy structure pipe, alloy steel pipe, bearing steel pipe, stainless steel pipe, as well as to save precious metals and meet special requirements of bimetal composite pipe, coating and coating tube. The variety of stainless steel pipe, the use of different, its technical requirements vary, production methods are also different. The current production of 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 methods.
(1) Mode of production
Stainless steel pipe According to the production of seamless pipe and welded pipe two categories, seamless steel pipe can be divided into hot-rolled tubes, cold rolled pipes, cold-drawn tubes and extrusion tubes, cold drawn, cold-rolled steel pipe two times processing;
(2) Section shape
The stainless steel pipe can be divided into round pipe and abnormity tube according to the cross-section shape. Special-shaped tube has rectangular tube, diamond tube, oval tube, six square tube, plus pipe and various sections of asymmetrical tubes. Profiled tubes are widely used in various structural parts, tools and mechanical parts. Compared with the circular tube, special-shaped tubes generally have a larger inertia moment and section modulus, a larger bending, torsional ability, can greatly reduce the weight of the structure, saving steel. The stainless steel pipe can be divided into equal section pipe and Variable section pipe according to the longitudinal profile shape. Tapered tube, stepped pipe and periodic section tube are the variable section tubes.
(3) Tube End shape
Stainless steel tube According to the state of the tube can be divided into light tubes and wire tube (with threaded pipe). The car silk tube can be divided into ordinary car wire tube (conveying water, gas, such as low-pressure pipe, the use of ordinary cylindrical or tapered pipe thread connection) and special threaded pipe (oil, geological drilling pipe, for the important wire tube, the use of special thread connection), for some special pipe, to make up for the thread on the strength of the pipe end, The tube end is usually thickened (thickened, thickened, or thickened inside and out) before the filament.
(4) Use classification
According to the use can be divided into oil well pipe (casing, tubing and drill pipe, etc.), pipeline pipe, boiler pipe, mechanical structure pipe, hydraulic prop pipe, gas cylinder tube, geological pipe, chemical pipe (high-pressure fertilizer pipe, petroleum cracking pipe) and ship tubes.
Three, stainless steel products The third largest category: Profiles
Profiles are the most extensive processing areas, products countless. Here's a list of the most common: stainless steel tableware, stainless steel door, stainless steel coffee table, stainless steel chair, stainless steel cabinet, stainless steel display frame, stainless steel stair armrest, Stainless steel anti-theft window, stainless steel screen, stainless steel sculpture, stainless Stell water tank, stainless steel NET, stainless steel lock, stainless steel screw, stainless steel reaction kettle, Even stainless steel soap and so on.
