Posted:2021-07-01 16:04:03

S275JR steel plate is a European standard non-alloy structural steel plate, which implements the EN10025-2 standard, and the corresponding number is 1.0044. S275JR steel plate is widely used in the field of machinery manufacturing. It is commonly used in various construction machinery, mining machinery manufacturing electric shovels, electric wheel dump trucks, excavators, loaders, coal mine hydraulic supports and other equipment and other structural parts.

Chemical composition of S275JR steel plate:
C≤0.24, Mn≤1.60, P≤0.045, S≤0.045, N≤0.014, Cu≤0.60

S275JR steel plate heat treatment: delivered in hot-rolled or normalized heat treatment state. If required, normalizing rolling can be used instead of normalizing. The buyer can choose the heat treatment state according to the demand, or additional inspection standard requirements and inspection level requirements, alloy element composition control requirements, thickness direction performance requirements (Z-direction performance requirements), etc., but it is necessary to communicate with the manufacturer in advance and sign a written agreement during enquiry or order.
