EN 10028-6 1.8865 Introduce
The EN 10028-6 steel standard is a European harmonised standard that provides requirements for hot-rolled flat steel products for pressure vessels. This standard sets chemical and mechanical property requirements, production control requirements, notch toughness, testing requirements and acceptance criteria. The purpose of the standard is to maintain a consistent product quality which makes it easier for organisations to buy, sell and manufacture steels.
Smelting temperature:1989°C - 1869°C
Application:Pressure flat steel products - Part 6: Weldable fine grain steel, quenched and tempered
EN 10028-6 1.8865 Material Mechanical Properties
EN 10028-6 is a standard specification for steel plates used in pressure vessel applications. It is a product of the European Standardization Institute (EN). Its mechanical properties include yield strength, tensile strength, hardness, ductility, and weldability, all of which can help to ensure that the steel meets the requirements of the application in terms of strength, durability, and serviceability.

EN 10028-6 1.8865 Material Machining Technology
When machining EN 10028-6 1.8865 steel, there are several factors that need to be taken into consideration in order to achieve the desired results. First, the type and size of the cutting tools must be correctly selected for the job. The cutting speed and feed rate also need to be adjusted to suit the chosen material and machining process for the best results. Additionally, cooling should be applied periodically as excessive heat buildup can cause the tools to wear prematurely and cause tool breakage. Finally, periodic chip breaking is necessary in order to minimize chip build-up and clogging of the cutting tool.
