ST52-3 low alloy steel is equivalent to domestic brand Q345. St52-3 new material number: 1.0570, old material number: 1.0841. St52-3 takes its tensile strength and yield point as its main characteristics. RINA EH40 hull structural ship plate products are generally used in the manufacture of various construction machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment used in mining and various engineering constructions And other structural parts.
The company always adheres to the RINA EH40 hull structural ship plate principle of "quality first, user first", and takes every cooperation seriously. It is our biggest wish that the steel material, specification and quantity can fully meet the requirements of users. With good reputation, high quality products and low price, we are willing to work together with old and new customers to create a great RINA EH40 hull structural ship plate cause. Customers are welcome to visit our company at any time. We are always ready to support you.
The advantage of hot-rolled stainless steel plate is that it can eliminate the damage caused by RINA EH40 hull structural ship plate metal structure in the process of ingot casting to a certain extent, eliminate some tiny defects in the structure, refine the grains of stainless steel material, promote the structure of steel closer, and improve the performance of the material as a whole. This kind of lifting is mainly manifested in the rolling direction, which can make the RINA EH40 hull structural ship plate steel no longer isotropic to some extent, and some defects such as bubbles, cracks and looseness formed during pouring can be eliminated under high temperature or high pressure.
In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and RINA EH40 hull structural ship plate pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.
The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
