Weldox 700 is a high-strength steel plate widely used in construction, mining, and transportation because of its excellent mechanical properties. However, as with any metal, Weldox 700 is susceptible to corrosion and weathering. Corrosion can significantly damage Weldox 700, including structural failure, while weathering can cause premature ageing and degradation. To ensure the longevity and durability of Weldox 700, it is essential to take proper measures to protect it from corrosion and weathering.
What are Weldox 700 plate?
Weldox 700 (Strenx 700) is a high-strength structural steel with outstanding properties. It features excellent weld ability, a high strength-to-weight ratio, and good formability. Depending on the thickness, the plate has a yield strength of 750-900 MPa. The plate dimensions range from 8mm to 180mm in thickness and up to 3100 mm in width, making it suitable for many applications such as bridge building, heavy equipment manufacturing, and offshore structures. Weldox can be used as an alternative to traditional steels like S355J2+N or S235JR in components subjected to higher stresses to take advantage of its excellent mechanical properties. Compared with the other grades available, Weldox offers one of the highest levels of toughness found amongst any grade steel plate available today. This makes it ideal for use across numerous industries where good impact resistance is essential for safety reasons!
How to Protect Corrosion and Weathering?
Choosing the Right Coating
Applying a coating is one of the most effective ways to protect Weldox 700 from corrosion and weathering. However, not all coatings are suitable for the Weldox 700 plate. The coating must be compatible with the steel’s chemistry to provide optimal protection. Several types of coatings are available, such as paint, powder coating, and galvanization. Each type has its strengths and weaknesses, but for Weldox 700, a zinc-based coating such as galvanization would be the most effective option. Zinc coatings provide excellent corrosion resistance and are highly durable.
Regular Inspection and Maintenance
Even with the right coating, Weldox 700 still requires regular inspections and maintenance to ensure that the coating remains effective and the steel plate remains in good condition. Inspecting the Weldox 700 for any signs of corrosion and weathering, such as rust spots or discoloration, is essential. Any issues should be addressed promptly. Regular cleaning and washing can also help to prevent corrosion and weathering.
Proper Storage
Weldox 700 should be stored in a dry, sheltered environment to prevent exposure to the elements. If the steel plate is left outside, it can be exposed to moisture, which can cause corrosion and reduce the steel’s strength. Weldox 700 should be elevated on a pallet or rack to prevent it from coming into contact with the ground or other materials. Keeping the steel plate off the floor is also crucial to prevent moisture from accumulating underneath.
Avoid Excessive Heat
High temperatures can also damage Weldox 700 through a process called tempering. Tempering occurs when the steel is exposed to temperatures above its hardening temperature, causing its microstructure to change, resulting in reduced strength. To prevent tampering, Weldox 700 should not be exposed to excessive heat. When welding Weldox 700 plate, it is essential to use low heat input to avoid tempering.
Proper Handling
Finally, to protect Weldox 700 from corrosion and weathering, it is essential to handle it properly. Mechanical damage or scratches on the surface can provide a place for corrosion to start. When handling Weldox 700, it should be lifted and moved with care to prevent damage to the steel plate’s surface.
Conclusion
Protecting Weldox 700 from corrosion and weathering requires consistent effort, but it is essential for the longevity and durability of the steel plate. Choosing the right coating, regular inspections and maintenance, proper storage, avoiding excessive heat, and proper handling are all critical to protecting Weldox 700. Weldox 700 can provide excellent performance and reliability for years by taking these measures.
