The theoretical weight of seamless steel pipe is the weight per meter of steel pipe calculated by the calculation formula: meter weight = (outer diameter - wall thickness) * wall thickness * 0.02466, in which the outer diameter refers to the farthest distance between the outer walls on both sides of the steel pipe, and the wall thickness is the thickness of the seamless steel pipe wall. The weight per meter of CCS EH40 hull shell steel seamless steel pipe is calculated by the formula. If you want to get the weight of the whole seamless steel pipe, you should multiply the actual length of the steel pipe.
Grade EH36 marine steel: E is the quality grade E, H is the high-strength building material, 36 is the maximum compression, and Z is the Z-direction stretching. Grade EH36 structural steel for high-strength hull refers to the steel used for manufacturing the hull structure produced according to the requirements of the classification society. Our company mainly supply Grade EH36 hot rolled plate, CCS EH40 hull shell steel, Grade EH36 angle steel bars and steel sections.
The purpose of CCS EH40 hull shell steel quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of CCS EH40 hull shell steel. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.
Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
