Tempering the important EN 10025 S690Q high strength steel welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve EN 10025 S690Q high strength steel strength, plasticity and toughness.

The results of adopting two-level EN 10025 S690Q high strength steel service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and EN 10025 S690Q high strength steel after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.

The use of low carbon steel is limited due to its low strength. The strength of the carbon steel can be greatly improved by properly increasing the manganese content in the EN 10025 S690Q high strength steel carbon steel and adding some alloy elements such as vanadium, titanium and niobium. If the carbon content in the carbon steel is reduced and a small amount of aluminum, boron and carbide forming elements are added, the ultra-low carbon bainite can be obtained, EN 10025 S690Q high strength steel which has high strength and good plasticity and toughness.
