Introduction and Application of S420N European standard structural steel:
For S420N European standard normalizing or normalizing rolling weldable fine-grained structural steel, S represents structural steel, 420 represents the yield value unit Mpa, and N represents normalizing or normalizing rolling in the delivery state. S420N steel plate is used for heavy-duty parts of buildings and bridges, boilers and pressure vessels, and welded structures, such as flood gates, storage containers, water supply containers, etc., and is suitable for room temperature and low temperature environments.
