P355NL Pressure Vessel Steel Plate
P355NL Pressure Vessel Steel Plate Detailed introduction
P355NL Pressure Vessel Steel Plate is a kind of low temperature steel plate used for manufacturing high temperature and high pressure vessels, which is a kind of steel of European standard EN10028. "P": indicates the European Standard Vessel Plate; "355": indicates that the minimum yield strength of the steel plate is 355, in MPa
The characteristics of P355NL Pressure Vessel Steel Plate include
1. good weldability and workability;
2. excellent low temperature toughness;
3. high strength and corrosion resistance;
4. meeting the chemical composition and mechanical properties requirements of European Standard EN10028.

tensile strength of 490-630 MPa, yield strength of 355 MPa and elongation of 21%;
Generally 6-250mm, width 1500-4020mm, length 3000-18000mm
P355NL Pressure Vessel Steel Plate cutting process
Steel plate factory inspection of the performance indicators meet the requirements in accordance with the cutting and processing process, you can cut processing and drawings under the material, the general thickness of the steel plate is not greater than 20mm preferred CNC plasma cutting or CNC laser cutting method, if the thickness of the steel plate is greater than 30mm or more. Usually will choose CNC flame cutting, you can control the cutting accuracy and time.
