How to repair corrosion pits on high strength RF 36 hull steel plate

The company now has high strength RF 36 hull steel plate oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than high strength RF 36 hull steel plate 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.

Our company can produce high strength RF 36 hull steel plate, EN10025-2 S355J2 structural steel plates and sheets up to 400mm thickness. S355J2 steel consists of S ( for structural steel), 355 (indicates the minimum specified yield strength value in MPa for thickness less than 16mm), J2( for a minimum impact energy value of 27J at -20ºC). EN S355J2 structural steel plates are suitable for cold flanging, delivery condition normalized rolled or as rolled.

When using high strength RF 36 hull steel plate, low-alloy high-strength steel, it is desirable to take advantage of its high strength and use a thinner section, not only for saving weight but also for the economy as much as possible. However, the corrosion factor must be fully considered. The thinner the steel section, the more attention should be paid to corrosion protection. Some low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but in some cases, take appropriate precautions and can even be used without being coated in the atmosphere.

Different from high strength RF 36 hull steel plate, the alloy wear-resistant layer of alloy plate is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium, nickel are also added. The carbides in the metallurgical structure are distributed in a fibrous shape, and the fiber direction is perpendicular to the surface. Carbide microhardness can reach HV1700-2000 and surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperatures, maintain high hardness, and also have good anti-oxidation properties. They are fully used within 500°C.

The toughness of steel such as high strength RF 36 hull steel plate is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.

Our company has its own steel plate manufacturing plant, processing plant and steel pipe plant. We can machine the steel according to the high strength RF 36 hull steel plate customer's requirements and meet the customer's requirements.
