Q235nh Grade Weathering Resistant Corten Steel Plate For Building Construction
Feature
-
Weathering steel plate is also called Cor-ten steel plate. It is a special kind of steel between stainless steel and plain carbon steel. Its characteristics are superior to ordinary carbon steel in atmospheric corrosion resistance and paint-ability, and its price is more economical and applicable compared with stainless steel.

Advantage
Weathering steel plate (that is, atmospheric corrosion resistant steel) is a series of low-alloy steel with low price and good quality, which is between ordinary steel and stainless steel. After being integrated into modern metallurgical new mechanism, new technology and new technology, it can be continuously developed and innovated, and it is one of the series of steel grades with the advanced level of super steel technology in the world. Weathering steel is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel, which has the characteristics of toughness, ductility, forming, welding and cutting, abrasion, high temperature and fatigue of high-quality steel. The weather resistance is 2-8 times that of ordinary carbon steel, and the painting property is 1.5-10 times that of ordinary carbon steel, so it can be used thinly, bare or simplified. This kind of steel has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, and labor and energy saving.
Feature
Weathering steel plate refers to low-alloy structural steel that can protect the rust layer from atmospheric corrosion and can be used to manufacture steel structures such as vehicles, bridges, towers and containers.
It has the characteristics of toughness, ductility, forming, welding, abrasion, high temperature and fatigue resistance of high quality steel. Compared with ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared with stainless steel, weathering steel contains only a few alloying elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, etc., and the total amount of alloying elements only accounts for a few percent, unlike stainless steel, which reaches more than ten percent, so the price is relatively low.
Application
Weathering steel plate is mainly used for steel structures such as railways, vehicles, bridges and towers exposed to the atmosphere for a long time. It is used to manufacture containers containing hydrogen sulfide corrosive medium in containers, railway vehicles, oil derricks, harbor buildings, oil production platforms and chemical petroleum equipment.
