EN 10025-4 S420M material number is 1.8825. This steel is a kind of weldable fine grain structural steels. For S420M heavy thickness plates, our engineers still suggest done Normalized heat treatment for them if customers want to improve their steel's property when using.Else,this steel must be done low temperature impacting test at -20℃ with minimum energy 40J on longitudinal direction.
EN 10025-4 S420M Structural Steel Plates Specification Thickness: 5mm-150mm
Width: 1500mm-4200mm
Length: 3000mm-18000mm
The dimensions, shape and tolerance of S420M steel plates shall be in accordance with EN10025-1:2004.
S420M structural steel plates are delivered in thermomechanical rolling: steel plates should be cut or cut with flame.
EN 10025-4 standard is a requirement for long products and hot rolled flat products from weldable fine grain structural steels in state after normalization or normalization rolling, thickness ≤ 250mm for steel grade S275, S355, S420 and thickness ≤ 200mm for steel grade S460. The given steels are intended for particularly loaded elements for weldable structures such as bridges, lock gates, storage tanks, and water tanks, used at ambient temperate and in low temperates. Structural steels must be referenced using standard symbols including but not limited to: M, ML.
