Commonly used cutting method of EN10155 S355J0W weathering steel plate

Commonly used cutting method of EN10155 S355J0W weathering steel plate

In the flame cutting process of EN10155 S355J0W weathering steel plate, the height of the cutting nozzle to the working surface is one of the main factors that determine the cutting quality and cutting speed. When using cutting nozzles with different para

Improve the ASTM A588 grade B steel plate weather resistance

Improve the ASTM A588 grade B steel plate weather resistance

Ni: nickel is also one of the elements to improve the weather resistance of ASTM A588 grade B steel plate, which can promote the formation of stable rust layer and also improve the welding performance of ASTM A588 grade B steel plate. However, too much ni

Importance of manganese and phosphorus in ASTM A588 gr. C steel plate

Importance of manganese and phosphorus in ASTM A588 gr. C steel plate

Manganese is the necessary element for deoxidation in the process of making ASTM A588 gr. C steel plate. The strength of ASTM A588 gr. C steel plate can also be improved by solution strengthening. In order to achieve enough high tensile strength, the mang

Content of carbon and silicon in EN10025-5 S355J2WP weathering steel plate

Content of carbon and silicon in EN10025-5 S355J2WP weathering steel plate

EN10025-5 S355J2WP weathering steel plate is designed with low carbon composition. The high carbon content is unfavorable to the impact toughness of steel, especially the impact energy of EN10025-5 S355J2WP weathering steel plate, and obviously damages th

ASTM A242 type1 weather resistant steel plate Cu and Cr elements content

ASTM A242 type1 weather resistant steel plate Cu and Cr elements content

Cu: copper can promote the formation of stable and dense rust layer on the surface of ASTM A242 type1 weathering steel plate, and also improve the weather resistance of ASTM A242 type1 weather resistant steel plate. However, the high copper content will c

There are two types of heat treatment deformation of Q355NH weathering steel plate

There are two types of heat treatment deformation of Q355NH weathering steel plate

Q355NH weathering steel plate must undergo a quenching process in the manufacturing process. Sometimes, due to poor workmanship, Q355NH weathering steel is often deformed due to too high and too low heat.

The Influence of cutting speed on the quality of A 709 Grade 50W weathering steel plate

The Influence of cutting speed on the quality of A 709 Grade 50W weathering steel plate

The cutting speed has a parabolic relationship with the cut surface roughness of A 709 Grade 50W weathering steel plate. As the cutting speed decreases, the surface roughness of A 709 Grade 50W weathering steel plate increases rapidly. With the increase o

Improve the quality of ASTM Corten A steel plate

Improve the quality of ASTM Corten A steel plate

When the rolling thickness of ASTM Corten A steel plate is more than 10 mm in the rolling pit, after the wear-resistant liner bites into the rolling mill, the splint should be opened quickly to reduce the friction between the splint and the bimetallic AST

How to prevent the surface of Q235NH weathering steel plate from cracking

How to prevent the surface of Q235NH weathering steel plate from cracking

Q235NH weathering steel plate cracking causes and countermeasures, poor weldability, resulting in failure to weld; set appropriate welding conditions. Repair bad weldments, resulting in poor welding. Matters needing attention in the cutting process. Conta

What are the advantages of Q355NH weathering steel plate after rust removal

What are the advantages of Q355NH weathering steel plate after rust removal

Q355NH weathering steel plate quickly forms a stable rust red oxide film, with uniform color and thickness, and is not easy to wipe off. Generally, the rust removal process is completed within 3 hours at an outdoor temperature of 25 degrees Celsius.
