DIN17102 E St E 315 steel is a German standard low-alloy high-strength steel plate widely used in multiple industrial fields. Below is a detailed introduction to its production process and application scope:
Production Process
The production process of DIN17102 E St E 315 Steel can be broadly divided into three main steps: steelmaking, refining, and rolling.
Steelmaking: This involves converting raw materials into molten steel through high-temperature and high-pressure smelting processes.
Refining: In this step, molten steel is transformed into steel blocks with the desired composition and properties. This is achieved by adding deoxidizers, carburizers, and other alloy elements to perform operations such as deoxygenation diffusion, removal of residual impurities, and composition adjustment.
Rolling: Steel blocks are processed into steel plates of the required thickness through hot or cold rolling processes. Factors such as rolling pressure, temperature, and coiling speed are controlled to adjust the dimensions, mechanical properties, and surface quality of the steel plates.
Application Scope
Due to its excellent performance, DIN17102 E St E 315 Steel is widely used in various fields, including:Machinery Manufacturing: It is used to manufacture various types of engineering machinery, such as drilling machines, electric shovels, electric wheel dump trucks, excavators, loaders, bulldozers, cranes, coal mine hydraulic supports, and other mechanical equipment and structural components.Construction: It is used to manufacture structural components for factories, general buildings, and other construction projects.Petrochemical Industry: It is suitable for manufacturing high-strength and high-durability pressure vessels, gas transmission pipelines, and other equipment.Shipbuilding and Bridge Construction: It also plays an important role in shipbuilding and bridge construction.
