How to distinguish Q235 steel and Q345 steel?
The appearance of Q235 steel and Q345 steel are almost the same. The color difference has nothing to do with the material of the steel, but is caused by the different cooling method after the steel is rolled. Under normal circumstances, the surface of the
Advantages and disadvantages of hot rolled steel
By definition, steel ingots or billets are difficult to deform and process at room temperature. They are generally heated to 1100°C to 1250°C for rolling. This rolling process is called hot rolling. Most steels are rolled by hot rolling. T
What are the differences between Q355NH steel and Q355GNH steel
Q355NH is a weather resistant structural steel. It is a low-alloy steel series between ordinary steel and stainless steel. It is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel. Q355NH steel has
Comparison of ordinary carbon steel and high-quality carbon steel
According to different steel quality, carbon steel can be divided into ordinary carbon steel and high-quality carbon steel. So what are the differences between the two?Ordinary carbon structural steel has wide restrictions on carbon content, performance r
Take you to understand the performance and use of angle steel
Angle steel is usually called an angle iron. It is a long strip of steel with two sides perpendicular to each other. Angle steel is composed of various load-bearing components and can also be used as a connection between components. Angle steel is widely
Three performance principles for choosing NM500 abrasion resistant steel plate
1. The principle of equal strengthNM500 abrasion resistant steel plate is generally used for welding low carbon steel and low alloy steel. For workpieces or structures that bear static or general loads, steel plates with the same tensile strength as the b
