thickness range of hardox 450 steel properties and features
In production and operation, the company always attaches great importance to product thickness range of Hardox 450 steel quality. Product quality is stable, performance index is superior, after-sales service is in place, the company's products have been exported to the United States, Southeast Asia, Africa, the Middle East and other countries and regions, occupying a large part of the overseas market thickness range of Hardox 450 steel. And a large number of famous enterprises at home and abroad have formed a solid strategic partnership with the company.
The company has strict control on the quality of thickness range of Hardox 450 steel. Each thickness range of Hardox 450 steel is inspected for the whole process, including raw material purchase, production process according to the procedures and relevant regulations. According to the technical standards and technical requirements, the composite quality inspection is carried out to confirm whether the thickness range of Hardox 450 steel meets the specified quality requirements. If the thickness range of Hardox 450 steel does not meet the quality requirements, the non conformity control shall be implemented, and the unqualified thickness range of Hardox 450 steel shall be removed, marked, registered and effectively isolated; the thickness range of Hardox 450 steel shall be inspected and confirmed for acceptance, release and delivery, and the quality certificate shall be issued.
Bridge steel thickness range of Hardox 450 steel is required to have higher strength, toughness, load and impact of rolling stock, and good fatigue resistance, low temperature toughness and atmospheric corrosion resistance. With the development of domestic railway construction towards high speed and heavy load, railway bridge steel developing in the direction of high speed, heavy load, long span, beautiful and novel structure, and full welding, higher requirements are imposed on the properties of steel for bridges. In particular, the development of cross-sea bridges has put forward higher requirements on the corrosion resistance of steel for bridges.
The steel plate cutting and processing instructions are as follows: steel plate cutting and steel plate cutting processing, as well as thickness range of Hardox 450 steel steel plate zero cutting processing. There are semi-automatic flame cutting, fully automatic CNC cutting, laser cutting and water cutting. The thickness range of steel plate that can be cut is 20650mm. In terms of thickness range of Hardox 450 steel steel plate cutting types, there are Q235B common plate, Q345B low alloy plate and 45 carbon bonded plate.
ASTM a588 is a high strength low alloy HSLA steel (high strength, low alloy) containing a small amount of alloying elements copper, chromium and AMP. Nickel. These alloying elements effectively improve the properties of a588 and expand its application range. Firstly, the alloy composition increases the thickness range of Hardox 450 steel yield point strength to 50 Ksi and the tensile strength to 70 Ksi. Secondly, a588 thickness range of Hardox 450 steel has high copper content, atmospheric corrosion resistance and long working time. Because of its excellent comprehensive performance, a588 angle steel is widely used in bridge, building and other structural fields.
