Material marine grade AH40 steel plate Chemistry

In recent years, in line with the development trend of iron and steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

We specialize in the production of steel pipe, including hot-rolled seamless steel pipe, ERW steel pipe, LSAW steel pipe, spiral welded pipe, stainless steel pipe, RHS / SHS. The company's annual sales volume is 75000 tons, more than doubling in the past five years, mainly used in machinery, pipeline, heating, oil drilling, chemical industry, agricultural irrigation, urban construction and other industries. So far, our pipeline service customers come from more than 40 countries.

Marine grade AH40 steel plate,Cold rolled coil products have accurate size and uniform thickness, and the thickness difference of coil is generally less than 0.01-0.03mm or less, which can fully meet the requirements of high precision tolerance. The surface quality of cold rolled products is superior, and there are no defects such as pockmarks, pressing iron oxide scale and so on, which often appear in hot rolled coils. According to the requirements of users, coils with different surface roughness can be produced (glossy surface or matte surface, etc.).

Try to use high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

We are engaged in corten steel, weathering steel, atmosphere corrosion resistant steel materials. After receiving your inquiry about the weathering steel, we will make quotation for you at the first time. Meanwhile, our professional team can give you valuable answers about all kinds of question about the weathering steel. For example, corten steel cost per square foot, S355J2WP equivalent, ASTM A242 steel properties, A588 steel yield strength, etc. If you have any demands or questions about weathering steel, please feel free to contact us.

After-sales service team is a key department to test the steel quality Product quality is always the foundation of our survival and development The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest,marine grade AH40 steel plate.
