How to optimize quality of S690QL young's modulus

Q345R steel is common low alloy steel, which is commonly used for boiler and pressure vessel. The delivery status includes hot rolling or normalizing. Q345R steel yield strength is 265-345MPa, tensile strength is 510-640MPa, elongation is greater than 21%, and zero degree V-shaped impact energy is greater than 34J. Q345R steel standard is GB713. Q345R steel has good comprehensive mechanical and technological properties. The content of S690QL young's modulus phosphorus and sulfur of Q345R steel is slightly lower than that of low alloy high strength steel plate.

The fake and inferior S690QL young's modulus, steel plates have no metallic luster and are light red or similar to pig iron for two reasons. 1. Its blank is adobe. 2. The rolling temperature of counterfeit and inferior materials is not standard, and their steel temperature is visually inspected. In this way, rolling cannot be carried out in the specified austenite area, and the performance of the steel plate will naturally not meet the standard.

S690QL young's modulus, 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.

The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
