General Information
9259, also known as Imacro EL700, is a grade with a low carbon content which gives the steel a very good toughness in as rolled condition.
8302, also know as Imacro M, is a weldable quenched and tempered steel with good toughness. The structure in the hardened condition is lath martensite.
* Designation followed by "*" is not an official EN standard grade but named according to the rules in EN 10027.
M-Steel®
The basis for the concept is that non-metallic inclusions are modified and controlled with calcium treatment in a way to minimize tool wear and to maximize chip control in machining operations. Our M-Steel treatment can be applied to any steel grade.
