The company adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the RINA grade E wash bulkhead steel production and life style of saving, environmental protection, civilization and low carbon, adheres to the new industrialization road and the sustainable development road. Actively carry out international trade and maintain stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, the United Kingdom, Japan, South Korea and Australia.
Our company supply low-alloy high-strength structural steel common grades below: Q345B / C / D / E, A572Grade 50 sheet, A572Gr.55 plate, RINA grade E wash bulkhead steel, A514 Grade B material, A709 Grade 50 steel. The company can provide low alloy structural steel plate thickness range of 6 ~ 200mm. Our low-alloy high-strength steel is widely used in various types of engineering structures such as steel structure construction, construction machinery, mining machinery, heavy vehicles, bridges, pressure vessels.
304 stainless steel plate products have strong corrosion resistance. For ordinary alkali solution and organic acid, inorganic acid has good corrosion resistance. This material RINA grade E wash bulkhead steel is a high alloy steel, which can resist corrosion in air or chemical corrosive medium.
Magnetic particle flaw detection is only suitable for detecting surface defects, which means that by laying magnetic powder on the surface of the equipment and using its aggregate shape on the surface defects of the magnetic material equipment to determine the position, size and shape of the defect. This RINA grade E wash bulkhead steel method has a relatively low cost and is easy for steel production enterprises to adopt in batches. However, for special steel profiles with deeper thickness, whether this method is used to detect hidden defects is yet to be verified.
Q235 is a kind of carbon steel. RINA grade E wash bulkhead steel, Q235 steel is widely used in steel structure construction because of its good toughness, good plasticity, certain elongation, good welding performance and heating performance. Q235A steel plate contains C ≤ 0.22%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.050, P ≤ 0.045. Q235B steel plate contains C ≤ 0.20%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.045, P ≤ 0.045. Q235C steel plate contains C ≤ 0.17%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.040, P ≤ 0.040. Q235D steel plate contains C ≤ 0.17%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.035, P ≤ 0.035.
First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
