We can process the steel materials according to your drawing. Or if you can not make drawing, please send us EN S355ML equivalent specific data and requirements, our technical department can make design and drawing for you, and then confirm with your technician or engineer. If all is OK, our processing center will process the steel materials according to the drawing. So no matter what size and shapes you need, we can meet demands at the most time.

Boiler steel refers to the special steel used to manufacture pressure components of steam boilers, such as steam drums. The boiler steel mainly means boiler steel plates and seamless boiler steel pipes. Boiler components not only bear pressure loads but are also heated by direct fire, so the requirements on the chemical composition and mechanical properties of boiler steel, EN S355ML equivalent are strict. In the chemical composition of boiler steel, EN S355ML equivalent, sulfur and phosphorus are strictly controlled. Tensile strength, yield point, elongation, impact energy value and 180 ° cold bending are required to be tested in boiler steel mechanical properties. In addition, strain aging impact test is also required for boiler steel. The quality control of boiler steel is slightly higher than that of pressure vessel steel.
