Surface quality of S690QL1 data sheet

The boiler steel is not only required to have good corrosion resistance at low temperature, but also required to have good oxidation resistance at high temperature for components working at high temperature. Especially for the components of superheater and reheater, when they S690QL1 data sheet work at high temperature, they are required not easy to be oxidized and peeled Generally, the development speed of oxidation depth at working temperature is required to be less than 01mm/year The addition of chromium, nickel, aluminum and silicon can improve the oxidation resistance of steel,S690QL1 data sheet., Wear resistant steel plate cutting: plasma cutting, carbon arc, grinding wheel saw can be used to cut large area of steel plate into the required shape. In order to reduce the cold crack of wear-resistant steel plate cutting, the wear-resistant steel plate should be preheated when cutting. The thicker the wear-resistant steel plate is, the higher the hardness is, and the higher the corresponding preheating temperature is. The preheating temperature should not exceed 200.Service concept: first time to understand customer needs, first time to solve customer worriesVision: to be the leading steel materials supplier in the worldWorking principles: Keep promises; Spare no efforts; Be practical and innovative; Pursue excellenceTalent concept: build a team with a dream and complete a dream with a team!Family culture: we rely on the principles of equality, trust, appreciation and family love to form a harmonious and warm family!we are the best professional steel manufacturer in China.
