hardox 500 vs ar500 sheet coil used in other structural elements

Normal strength shipbuilding structural steel is divided into four grades: A, B, C, and D. The yield strength (not less than 235N/mm^2) of HARDOX 500 vs ar500 these four grades is the same as the tensile strength (400~520N/mm^2). However, the impact properties of steel plates at different temperatures are different.

Participating tenders with clients is part of our HARDOX 500 vs ar500 business. Every year, we support a lot of clients to win tenders and supply steel materials to their govenment progects or state owned enterprise. Until now, we have built HARDOX 500 vs ar500 long-term cooperation for many govermental departments of different countries such as Peru, Bangladesh, Indonesia, Egypt, Qatar, etc.. And we have built certain influence and credibility on the International market.

Laser cutting is that the horizontal laser beam emitted by the laser changes into a vertical downward laser beam through the 45° total reflector, and then focuses through the lens, forming a tiny spot at the focal point. When the spot hits the material, the material is heated to the vaporization temperature quickly, and evaporates to form a hole. With the movement of the beam on the material such as HARDOX 500 vs ar500, the auxiliary gas (carbon dioxide gas, oxygen, Nitrogen, etc.) blow away the melted slag, make the hole continuously form a very narrow width (such as about 0.1mm) cutting seam, and complete the cutting of materials.

In the past 10 years, domestically-made offshore platform steel has been widely adopted in China's offshore oil projects, and offshore platform steel has gradually developed in the direction of high strength. Relevant data show that the pile legs, pile boots, cantilever beams and other key parts of the jack-up platform require high load. In order to improve the stability of the hull during towing after floating, it needs to be lightweight, and high-strength steel plates must be used.
