EN 10025 S690QL high strength steel carbon steel heavy plate

API 5L X42 steel plate (L290) is pipeline steel. API 5L X42 steel yield strength is 290 - 495 MPA, and the yield ratio is not more than 0.9. The EN 10025 S690QL high strength steel delivery status of API 5L X42 steel plate is hot rolling or controlled rolling. API 5L X42 steel plate (L290) is mainly used for the production of oil and gas gathering and long-distance pipelines or coal and building material slurry pipelines, to serve for transportation of gas, water and oil in the natural gas industry.

In the manufacturing process of boiler pressure components, raw materials must undergo complex processing deformation and welding, so the steel used to manufacture the boiler must also have good process performance. All materials EN 10025 S690QL high strength steel used to manufacture pressure parts must conform to the relevant national standards for boiler steel. The defects such as delamination, non-metallic inclusion, porosity and looseness in the steel shall be as few as possible, and white spots and cracks are not allowed.

Tempering the important EN 10025 S690QL 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 S690QL high strength steel strength, plasticity and toughness.
