Improvement measures of Q355NH weathering steel plate

Improvement measures of Q355NH weathering steel plate

When the Q355NH weathering steel plate with a thickness of more than 10 mm is rolled in the rolling pit, after the wear-resistant liner bites into the rolling mill, the splint should be opened quickly to reduce the gap between the Q355NH weathering steel

Interaction between Q355NH weathering steel plate and Q235 steel

Interaction between Q355NH weathering steel plate and Q235 steel

Q355NH weathering steel is composed of the following alloy components by weight: carbon: 0.12-0.21, silicon: 0.2-2.0, manganese: 0.7-2.0, sulfur ≤0.036, phosphorus ≤0.034, copper: 0.10-0.40, aluminum:0.2, the remaining is iron and trace impurities.

Rust characteristics of Q355NH weathering steel plate

Rust characteristics of Q355NH weathering steel plate

Q355NH weathering steel plate is characterized by uniform rust red color, good color fastness and adhesion, no peeling, no slag falling, no rust water flowing in the later stage, and super corrosion resistance.

Welding preheating and post-welding heat treatment of ASTM A588 Grade C weathering steel plate

Welding preheating and post-welding heat treatment of ASTM A588 Grade C weathering steel plate

After welding, cooling and shrinkage can be uniform at the same time, so as to significantly reduce the ASTM A588 Grade C weathering steel plate welding stress and welding deformation. Post-welding heat treatment of ASTM A588 Grade C weathering steel plat

What are the annealing types of Q295NH steel plate

What are the annealing types of Q295NH steel plate

Full annealing. The process of heating Q295NH steel plate to 30~50℃ above AC3, complete austenitizing, followed by slow cooling, and obtaining near equilibrium microstructure is called complete annealing. Mainly used for medium carbon carbon steel and med

The important role of Q295NH weathering steel plate annealing

The important role of Q295NH weathering steel plate annealing

The purpose of Q295NH weathering steel plate annealing is as follows: reduce the hardness of Q295NH weathering steel plate, improve the plasticity, in order to facilitate cutting and cold deformation processing.

Purpose of tempering JIS G3114 SMA 50 AW steel plate

Purpose of tempering JIS G3114 SMA 50 AW steel plate

Reduce or eliminate the internal stress of JIS G3114 SMA 50 AW steel plate during quenching to prevent deformation and cracking of workpiece. The toughness of JIS G3114 SMA 50 AW steel plate was improved by tempering, and the strength and hardness of JIS

What is the function of EN10025-5 S235J2W steel plate quenching

What is the function of EN10025-5 S235J2W steel plate quenching

The purpose of quenching is to improve the hardness, strength and wear resistance of EN10025-5 S235J2W steel plate, and give full play to the performance potential of EN10025-5 S235J2W steel plate. However, quenched martensite is not the final structure r

What is the function of EN10155 S355J0W weathering steel plate normalizing

What is the function of EN10155 S355J0W weathering steel plate normalizing

Low and medium carbon steel and EN10155 S355J0W weathering steel plate are normalized to improve cutting performance. As the production cycle of EN10155 S355J0W weathering steel plate normalizing is shorter than annealing and the operation is convenient,
