The company attaches great importance to systematic management, and has passed the CCS E40 chemical tanker steel ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on CCS E40 chemical tanker steel quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.
CCS E40 chemical tanker steel, Medium and heavy steel plate is a kind of steel plate with outstanding characteristics. First of all, there are many kinds of thickness of medium and heavy steel plate, which are generally relatively thick. Secondly, the thickness of medium and heavy steel plate is relatively thick, so it can be used for high strength application such as bridges. Thirdly, the corrosion resistance and wear resistance of medium and heavy steel plate are much better than ordinary steel plate.
Wear resistant steel plates are mainly divided into three types: general-purpose, impact resistant and high-temperature resistant type, and their applications are also different. However, they have basically been involved in various industrial production fields, including metallurgy, coal, cement, power, glass, mining, building materials, brick and tile industries. Compared with other materials, CCS E40 chemical tanker steel, wear resistant steel plates have high cost performance.
Penetration testing technology is only suitable for detecting surface defects. It uses penetrant to apply on the surface of the CCS E40 chemical tanker steel steel plate, then wipes the excess penetrant with the cleaning solution, and then smears the developer. The penetrant remaining in the defect is adsorbed by the developing material, so as to observe the shape of the defect and determine the type of defect. This CCS E40 chemical tanker steel method requires multiple wipes before and after the inspection, the process is more cumbersome, and can not detect internal defects and rough and dirty steel plates.
Q420C steel belongs to low alloy high strength steel. Q420 is named as the steel with yield strength of 420MPa, C means the impact temperature is 0 ℃, and Q is the abbreviation of yield strength. Chemical composition of Q420C steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420C steel are: yield strength ≥ 340 Mpa, tensile strength 500-680 Mpa, elongation after fracture ≥ 18%, impact energy 34J. CCS E40 chemical tanker steel, Q420C steel has good mechanical properties and weldability, good cold and hot workability.
