A871 Gr60 Weather resisting steel

A871 Gr60 Weather resisting steel

Grade: Grade 60
Type: Weather resisting steel plate
Standard: ASTM A871
Specification: Thickness:<=200mm
Application: A871 Gr60 Weather resisting steel is mainly used for railway, vehicles, bridges, towers and other steel structures used in long-term exposure to the atmosphere. Structural parts for the manufacture of containers, rolling stock, oil derrick, harbor construction, oil platforms and chemical petroleum equipment container containing hydrogen sulfide and other corrosive media.

 A871 Gr60 Weather resisting steel Introduction:Atmospheric corrosion can substantially A871 Gr60 weathering steel in most environments enclosed in copper or copper-free carbon steel. When fully exposed to the atmosphere, this steel may be exposed (uncoated) used for a variety of purposes in the state. 

A871 Gr60 Weather resisting steel Usage:A871 Gr60 Weather resisting steel refers to a weathering steel rust resistance to atmospheric corrosion protection, it can be used in the manufacture of vehicles, bridges, towers, containers and other steel low-alloy structural steel. Compared with carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared to stainless steel, only trace amounts of alloying elements, alloys such as weathering steel elements of total phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, etc. is only a few percent, rather than as stainless steel, reached a hundred per dozen, so the price is relatively cheap。
