Stainless steel is a high-alloy steel that can resist corrosion. Has a beautiful surface, do not have to go through the plating color or paint and other surface treatment, so many machinery factory to show their own is stainless steel, often do not do any paint treatment, and the black material (the so-called black material is the general steel name) must be rust-proof treatment.

The morphological classification of stainless steel Stainless steel can be divided into five categories: coil, plate, profile, steel pipe and parts, the most important is coil and plate. Profile is a variety of different types of materials made of plate, angle steel, flat steel, I-beam, channel steel. Steel pipe mainly refers to seamless steel pipe, and seamless steel pipe is the opposite of welded pipe, the difference is whether a forming. Parts mainly refer to elbows and flanges and other small things. Coils and plates are actually the same, but the factory forms are different. Coils are rolled one by one, and plates are rolled one by one. If the factory is a plate, it is also called an original plate, which is generally a thick plate, because if it is very thick, it cannot be rolled, and generally it cannot be rolled over 16mm.
The characteristics and uses of our main stainless steel types: 304, as a widely used steel, has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, stamping, bending and other hot workability, no heat treatment hardening phenomenon, non-magnetic, the use temperature of minus 193 degrees to 800 degrees. Uses: tableware, kitchenware, water heaters, boilers, auto parts, medical equipment, food machinery, storage wine, pressure vessels (chemical machinery, chemical equipment). 316 low carbon, add MO elements, so his corrosion resistance and atmospheric corrosion resistance and high temperature strength performance is particularly good, can be used under harsh conditions, suitable for use below 900 degrees, non-magnetic. Uses: equipment used in sea water, chemical, dye, paper, acetic acid, fertilizer and other production equipment, food industry and coastal facilities, products with special requirements against intercrystalline corrosion.
