Stainless steel production increased in most countries during 2014
Stainless steel Angle is both sides mutually perpendicular Angle of strip steel. Equilateral Angle steel and stainless steel is not equilateral Angle steel stainless steel. Two equilateral Angle steel stainless steel edge width is equal. Its specification in a thick edge width x width x while millimeters said. Such as “< 25 * 25 * 3”, it indicates that the edge width is 25 mm, to 3 mm thick of stainless steel equilateral Angle steel. Also available model, said the model is the number of centimeters wide, such as < # 2.5. Model does not represent the size of the same type of different edge thickness, thus the contract and other documents will be the width, and thickness of the stainless steel Angle bar size fill in complete, avoid expressed in model alone. The specifications of the stainless steel hot-rolled equilateral Angle steel for # 2 – # 20.
All metals when with the oxygen in the air, can form a layer of oxide film on the surface. In ordinary steel is formed on the surface of the oxide will continue to form oxidation rust. But because the stainless steel containing more than 11%
Chromium, so the change in the nature of the oxide layer, can prevent further oxidation, and if the oxide film by chance is removed, the new oxidation film can form again, continue to protection.
In fact, stainless steel containing at least 18%, the most commonly used steel grades are in bud at least 8% of nickel.
Typical application
The type 430 is pretty good in a room, but to achieve satisfactory outdoor performance requires the use of steel containing nickel. The type 304 is widely used in curtain wall, side wall, roof, etc. And become a problem of air pollution in coastal areas and its place,
Type 316 stainless steel is more preferable. About how to select the suitable steel grade, please see the Advantages for Architects “manual.
European standards – European standard part 3 section 1.4, including the construction application on brand 304 l, 316 l and 2205.
The product shape
Stainless steel is mainly according to the standard metal shapes and sizes for production, and also add many special shape and casting. The most commonly used products are sheet and strip.
Surface state
Can buy all kinds of surface processing and finished product, the surface can be high reflection or matte; Smooth, polished or embossing; Colored or even lead tin alloy to produce similar to the concept of lead.
processing
Used for welding, forming, cutting technology can be used for ordinary carbon steel stainless steel, but the equipment of the given value to do some adjustments, and to realize the strength of the stainless steel is quite high. Adjusted according to the differences and can easily be processing of stainless steel.
design
Architects use stainless steel to achieve their design ideas of permanent expression has been more than 60 years. Some application is very conspicuous, such as New York Chrysler
Building. But in many other internal and external application of less dramatic, but in the structure of the aesthetic and performance plays an important role.
Stainless steel as a long service life, has a high degree of integrity, building materials, the effect obtained such as the national institute of civil engineering standard ANSI/ASCE – 8-90 “size” cold forming of stainless steel construction design and
NiDI and Euro Inox jointly published the “stainless steel design guide” design criteria of design specification approval.
