HIC Test Acceptance Grade: Acceptance grade: Grade I, Grade II, grade III CLR% crack length ratio, CTR% crack [TJC STEEL]thickness ratio, CSR% crack sensitivity ratio. Application Countries: P355NH is used in Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, [TJC STEEL]Luxembourg, Malta, The Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland, the United Kingdom. S355NL Steel Plate belongs to standard of EN10025-3. Full Name: Normalizing/Normalizing rolled weldable fine grain structure steel plates. This standard together with EN10025-1 replaces EN 10113-1:1993 hot rolled steel products with weldable [TJC STEEL]fine grain structure -- Part 1: General Conditions and EN 10113-2: Hot-rolled weldable fine grain structural steel products - Part 2: Conditions for normalizing/normalizing rolled steel. When the temperature is not less than -20°C, the minimum impact energy is specified, denoted by N. When the temperature is not less than -50°C, the minimum impact energy is specified, denoted by NL.
Name of Steels: S: for structural steel, N: state, capital L: [TJC STEEL]specifies the level of minimum impact energy at a temperature not lower than -50°C. Property Performance Strength: Tensile strength: RM630-450mpa. Yield strength: 355-275mpa, elongation after fracture 21-22%. National Standards Corresponding [TJC STEEL]to S355NL: GB: Q345E JIS: SEV245 ASTM: Type 3 Grade 50 The Typical Application of S355NL Steel Plate: Construction machinery, mining [TJC STEEL]machinery, metallurgy, environmental protection, water conservancy and hydropower structural parts. |
