Types
China mainly has the following types Steel type:. Later, other steel grades with lower nickel content control appeared. As for the national standard grade of the extended steel grade developed by individual steel mills in China during this period, it continued to reduce the nickel content and increase the manganese content.

Stainless steel rods are widely used in hardware, machinery, petroleum, chemical industry, shipbuilding, offshore engineering, boilers, heat exchangers, aerospace, environmental protection, high temperature resistance, low temperature refrigeration , corrosion resistance, automobiles, medicine, food, electricity, water conservancy, construction, fertilizers, urea, nuclear power, new energy equipment and other industries are deeply favored by users.
Stainless steel, with the characteristics of acid resistance, alkali resistance, high density, polishing without bubbles, and no pinholes, is a high-quality material for the production of various watch cases, watch strap bottom covers, etc. Stainless steel is mainly used to make decorative pipes, industrial pipes and some shallow-stretched products

Effects of stainless steel
Stainless steel will not cause corrosion, pitting, rust or wear. Stainless steel is also one of the strongest materials among metal materials used in construction. Because stainless steel has good corrosion resistance, it allows structural components to permanently maintain the integrity of their engineering designs. Chromium-containing stainless steel also combines mechanical strength and high elongation and is easy to process and manufacture components to meet the needs of architects and structural designers.
Typical uses
Most uses require maintaining the original appearance of the building for a long time. The main considerations when determining the type of stainless steel to select are the required aesthetic standards, the corrosive nature of the local atmosphere and the cleaning regime to be adopted. Increasingly, however, other applications are simply seeking structural integrity or impermeability. For example, roofs and side walls of industrial buildings. In these applications the cost of construction to the owner may be more important than aesthetics and the surface may not be very clean. Stainless steel works quite well in dry indoor environments. But in rural and urban areas, frequent cleaning is required if you want to maintain its appearance outdoors. In heavily polluted industrial areas and coastal areas, the surface will be very dirty and even rusty. However, nickel-containing stainless steel is required to obtain aesthetic effects in outdoor environments. Therefore, stainless steel is widely used in curtain walls, side walls, roofs and other construction purposes. However, stainless steel is best used in severely corrosive industries or marine atmospheres. Stainless steel sliding doors Now people have fully realized the advantages of using stainless steel in structural applications. There are several design guidelines that include stainless steel. Because duplex stainless steel has integrated good atmospheric corrosion resistance with high tensile strength and elastic limit strength, this steel is also included in the European standards. Product Shape In fact, stainless steel is manufactured in full standard metal shapes and sizes and there are many special shapes. The most commonly used products are made of thin plates and strips. Medium and thick plates are also used to produce special products such as hot-rolled structural steel and extruded structural steel. There are also round, oval, square, rectangular and hexagonal welded pipes or seamless steel pipes and other forms of products including profiles, bars, wires and castings.
Surface Conditions
As will be discussed later, a variety of commercial surface finishes have been developed to meet the aesthetic requirements of architects. For example, the surface can be highly reflective or matte, it can be glossy, polished or embossed, it can be colored, colored, electroplated, or etched with patterns on the stainless steel surface, or it can be brushed, etc. to meet the designer's needs. Various requirements for appearance. It is easier to maintain the surface condition with only occasional flushing to remove dust. Due to its good corrosion resistance, surface graffiti contamination or other similar surface contamination can be easily removed.
