About Product

Stainless steel 304 and 316 are both types of stainless steel, but they have different properties and applications.Stainless steel 304 is a standard 18/8 stainless steel, meaning it contains 18% chromium and 8% nickel. It is often used in kitchen equipment, food processing, and other applications where corrosion resistance is important.Stainless steel 316, on the other hand, contains 16% chromium, 10% nickel, and 2% molybdenum. This additional molybdenum gives 316 stainless steel better resistance to corrosion, particularly in chloride environments such as coastal areas and areas with de-icing salts. As a result, 316 stainless steel is often used in marine applications, chemical processing, and medical devices.In summary, the main difference between stainless steel 304 and 316 lies in their chemical composition, which gives 316 stainless steel higher corrosion resistance in certain environments.

Yes we accept delivery by train.We established a factory in Shaan Xi Province. It makes delivery to Middle Asia more convenient and quick by train.

Black pipe is plain steel pipe without any protective coatings. Black pipe is used for a variety of applications around the home. It is very common to see black pipe used for your natural gas line and sprinkler system lines. Since black pipe has no protective coating, it may rust easily in wet or humid environments. To stop the pipe from rusting or corroding on the outside, you should provide a layer of protection on the outside of the pipe. The easiest method is painting it.

RHS stands for Rectangular Hollow Section, that is rectangular steel pipe.We also have square hollow section steel pipe, according to standard: ASTM A500 , EN10219 , JIS G3466 , GB/T6728 cold formed square and rectangular steel pipe.

How is steel used in Highways?In a globalized economy, America’s infrastructure is important to our competitive edge. We have “4 million miles of roads, 600,000 bridges (link to bridge page), 26,000 miles of commercially navigable waterways, 11,0000 miles of transit lines, 500 train stations, 300 ports, 19,000 airports, 55,000 community drinking water systems, and 30,000 wastewater plants. . . already built.”2 Instead of losing ground, let’s strengthen what we have and advance our global position.Instead of the glass being half empty with billions of investment dollars needed in improvements, how can we build on what we have?We have cost-competitive solutions. Roadways that use continuously reinforced concrete pavement (CRCP) have been shown to improve fuel efficiency in heavy vehicles by as much as 20%.CRCP means increased environmental benefits because it is made of 100 percent recycled material and is 100 percent recyclable and reduces thermal heat in cities.CRCP means less time in traffic delays for motorists because of fewer road repairs and reconstruction.AISI recommends utilizing all funding mechanisms available including the Highway Trust Fund, Public Private Activity Bonds, Vehicle Miles Traveled and others.The Department of Transportation reported that every $1 billion federally invested in highway capital supports nearly 35,000 American jobs.
