P460 Steel Family Overview
P460 represents a family of high-strength structural steels defined by standards such as EN 10028 (pressure vessel steels) and EN 10025 (structural steels). The designation indicates a minimum yield strength of approximately 460 MPa for relevant thickness ranges.
P460 Grade Variants
  • Pressure-vessel steels (EN 10028-3): P460N, P460NH, P460NL1, P460NL2
  • Quenched and tempered pressure-vessel steels (EN 10028-6): P460Q, P460QH, P460QL1, P460QL2
  • Structural equivalents: S460 (EN 10025) with similar strength but different chemistry and impact requirements
Typical Chemical Composition (EN 10028-3, P460N/NL1/NL2)
Approximate composition ranges vary by specific sub-grade and product thickness:
Element Composition Range
Carbon (C) ~0.18-0.22% max (typically 0.15-0.20%)
Manganese (Mn) ~1.50-1.80%
Silicon (Si) ~0.20-0.60%
Phosphorus (P) ≤ 0.025%
Sulfur (S) ≤ 0.015-0.020%
Chromium (Cr) up to ~0.30-0.50%
Nickel (Ni) up to ~0.60-1.00%
Molybdenum (Mo) up to ~0.10-0.30%
P460 Sub-Grade Designations
  • N / NH: Normalized or normalized-rolled; NH for higher notch toughness
  • NL1 / NL2: Normalized, low-temperature impact tested at −40°C or −50°C
  • Q / QH / QL1 / QL2: Quenched and tempered variants with different toughness and thickness ranges
Important Specification Note:
Always specify the exact standard and grade (e.g., "EN 10028-3 P460NL2") and refer to mill test certificates for precise composition data required for design, welding, and regulatory compliance.
E355 (Adipic Acid) Overview
E355 is the food additive code for adipic acid, used primarily in the food industry for acidity regulation and flavor enhancement in soft drinks, jellies, and powdered beverages.
Chemical Identity
  • Common name: Adipic acid
  • Food additive code: E355
  • IUPAC name: Hexanedioic acid
  • Molecular formula: C₆H₁₀O₄
  • Molar mass: 146.14 g/mol
Structural Details
Adipic acid is a dicarboxylic acid with two carboxyl (-COOH) groups. Structural formula: HOOC-(CH₂)₄-COOH
Food Grade Specifications
In food applications, E355 is typically high-purity adipic acid with:
  • High assay (typically ≥ 99% adipic acid)
  • Very low levels of impurities (water, ash, related acids)
