Definition: stainless steel stainless steel is a kind of resistance to corrosion of high alloy steel. The surface is beautiful, without plating color or paint surface treatment, so a lot of machinery factory to show their stainless steel, often without any paint processing, and black material (the so-called black material is usually steel is called) we must carry out anti rust treatment.
Simple classification: stainless steel stainless steel can be roughly divided into 200 series, 300 series and 400 series of three categories, the 300 series is the most commonly used, 200 series and 400 series of a process is the 300 series of alternatives, but strictly speaking is not called the 400 series stainless steel, stainless iron, because there is not nickel containing elements, so the magnet can hold. And the 200 and 300 series are nickel, so there is no magnetic, iron suction is not to live.
Stainless steel form classification: stainless steel can be divided into coil, plate, profiles, steel pipe and parts five major categories, the most important thing is roll and board. Profiles are made of plates of various shapes, including angles, flat steel, I-beam and channel steel. Steel pipe mainly refers to seamless steel pipe, and seamless steel pipe relative to the welded pipe, the difference is whether or not a molding. Parts mainly refer to elbows and flanges and other small things.
