19Mn6 Boiler steel plate , 19Mn6 Boiler steel plate Chemical Composition & Mechanical Properties
DIN 17155 19MN6 is an outdated German specification for pressure vessel steel. This technical specification has now been superseded by EN 10028 but we have provided details of 19MN6 on our website for cross reference purposes.
19Mn6 steel research after forging and heat treatment can replace 20, 25 steel for use as boiler forgings for raw materials, chemical composition, mechanical properties and microstructure analysis to determine compliance with national standards, and then cutting, forging, heat treatmentsampling.
