Corrosion Behavior of S450EW Lowalloy Weathering Steel in Weathering steel is widely used in various fields due to its excellent mechanical properties and high corrosion resistance. The effect of chromium content on the S450EW weathering steel in cyclic immersion test was studied. The results indicated that the corrosion resistance of S450EW weathering steel is closely related to chromium content.5
May 01, 2014 · According to the characteristics of high strength weathering steel, this paper designs to develop anexperimental steel S450EW with yield strength higher than 450MPa.Through the study,it has been found that with decreasing cooling rate, the organizational changed largely, while ferrite and pearlite gradually transformed to martensite and a small amount of ferrite, then finally tomartensite
Corrosion of wagon body can affect the safe operation of railway wagon, while the new type highly corrosion resistant weathering steel S450EW developed by Baosteel independently has a corrosion resistance 50% higher than the existing products, and its high strength performance can reduce the weight of wagon body.
SSAB Weathering steels are extremely high strength. They are protected by a patina layer of rust that is formed in the oxidation process a process that is vastly speeded up in corrosive, sulfur rich environments. Thanks to this, unpainted weathering steels (often referred to as atmospheric corrosion resistant steel) require minimum maintenance.
The steel is self protectingthe rust layer on the surface becomes a tight oxide layer that slows down the progress of corrosion. The steel is an economical, long lasting and fully recyclable material. Weathering means that due to their chemical composition steels exhibit increased resistance to atmospheric corrosion compared to unalloyed steels.

Weathering steel, also known as corten steel or COR TEN steel, refers to a type of high strength steel alloy that develops a protective oxide film on its surface. Weathering steel exhibits superior corrosion resistance traits compared to regular carbon steel due to this unique property and its superior yield strength capability.
Based on the results of the accelerated corrosion tests and rust layer analysis, the roles of Cu and Cr against corrosion are discussed, providing HPS with chemical specification which has been industrially successful to produce weathering steel for bridge structure.
The results indicated that the corrosion resistance of S450EW weathering steel is closely related to chromium content. The addition of chromium significantly inhibited the weathering steel
High strength, corrosion resistant weathering steel pipe is available in the various sizes listed. ASTM A847 is considered the ASTM equivalent for Cor Ten® pipe; Supplied in standard 21 lengths or by special order lengths; Learn more about ASTM A847; Mechanical Properties. Yield =
Weathering steel. Weathering steel or weather resistant steel are colloquial terms used to describe structural steels with improved atmospheric corrosion resistance. These steels are high strength low alloy steels that under normal atmospheric conditions give an enhanced resistance to rusting compared with that of ordinary carbon manganese steels.
Technical Advisory Uncoated Weathering Steel in Structures. October 3, 1989. Technical Advisory 5140.22. PURPOSE. To provide engineers with suggested guidelines for proper application of uncoated (unpainted) weathering grade steels in highway structures and recommendations for maintenance to ensure continued successful performance of the steel.
