What is the difference between weathering steel red rust and ordinary rust?

Why are all weather resistant steel plates red corroded, and what is the difference with ordinary red corroded steel plates?

At present, many steel plates in life are made of weather-resistant steel, especially landscape weather-resistant steel has been frequently used in recent years. So, why is the weathering steel "weathering steel" all red rust, what is the ordinary red rust steel plate? What's the difference?

The weather-resistant steel plate of the invention has the characteristics of toughness, ductility, forming, welding, cutting, abrasion, high temperature, fatigue and so on of high-quality steel. The weather resistance is 2 to 8 times that of ordinary carbon steel, the coating performance is 1.5 to 10 times, it can be thinner and used, and the coating can be bare or simplified. The steel has the characteristics of rust prevention, corrosion resistance, long service life, thinning to reduce parts consumption, manpower saving, energy saving, which is beneficial to parts manufacturers and users. And the recovery of the material can be 100% recovered without any maintenance, and no maintenance is required in the later stages of weathered steel.

Red rust steel plate is a general term for steel plate, and the name of the steel plate after rust is red rust. However, due to different materials, different production processes and different ways of use, they are divided into weathering steel red rust steel plate and ordinary red rust steel plate.

Common ground: 1. All surfaces show red rust. 2. Surface oxidation layer treatment is required before rust. 3. The rust layer on the surface of the naturally rusted red rust steel plate is not uniform. 4. All can be obtained by manual rust removal.

Different opinions: 1. Ordinary red rust steel plates generally use Q235B and Q345B. These two materials are ordinary weathering steel red rust steel plates, such as 09CU and SPA-H. 2. The color of ordinary red rust steel plate is deep red, tending to black red.

When using ordinary red rust steel plates, yellow rust will appear on the hands, and there will be a layer of rust and skin peeling in the later stage of severe corrosion.
