13CrMo4-5 steel plate delivery status and production process is strictly produced according to EN10028-2 standard. Delivery status: normalizing + tempering, tempering. The 13CrMo4-5 alloy plates thickness below 100mm, it is normalizing + tempering; Thickness 100mm-150mm, the plate is delivered in normalizing + tempering or quenched and tempered;150mm-250mm is delivered in tempered condition. The requirements for flaw detection levels, and Z-direction functional requirements can also be added.
The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with RINA grade E wash bulkhead steel, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.
As the thickness and hardness of RINA grade E wash bulkhead steel increase, the tendency to crack at the cutting edge increases. In order to prevent the RINA grade E wash bulkhead steel from cutting cracks, preheating should be carried out before RINA grade E wash bulkhead steel cutting. Special attention should be paid to preheating to make the entire RINA grade E wash bulkhead steel interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole RINA grade E wash bulkhead steel cannot be preheated, the partial preheating method can be used instead.
Our steel products are widely used in petroleum and natural gas, chemical industry, shipbuilding, automobile manufacturing, power generation, mining, and other industries. The products RINA grade E wash bulkhead steel are sold in more than 20 provinces, cities and all over the world. The company has strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high-quality products.
After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
