Overview

ASTM B333-03(2018) is the ASTM International standard specification for nickel-molybdenum alloy plate, sheet, and strip. This widely recognized standard sets requirements for the manufacture and quality control of flat-rolled nickel-molybdenum alloys designated as UNS N10001, N10665, N10675, N10629, and N10624, used primarily in general corrosive service. The standard outlines the necessary chemical compositions, mechanical properties, dimensional tolerances, and product marking, ensuring consistent product performance and compliance within critical industrial applications.

Key Topics

• Scope and Covered Products

  • Applies to plate, sheet, and strip of nickel-molybdenum alloys
  • Includes both hot-rolled and cold-rolled material
  • Solution annealing and descaling are required for optimal quality, unless a bright finish is achieved by annealing in a controlled atmosphere

• Chemical Composition

  • Specifies limits for nickel, molybdenum, iron, chromium, carbon, silicon, cobalt, manganese, phosphorus, sulfur, and additional trace elements
  • Ensures alloy consistency and corrosion resistance

• Mechanical Properties

  • Sets minimum requirements for tensile strength, yield strength, elongation, and hardness
  • Includes references to ASTM standards for measurement and conversion (such as ASTM E112 for grain size and ASTM E140 for hardness conversions)

• Dimensional and Physical Properties

  • Defines acceptable density values for weight calculations
  • Strict tolerances for thickness, length, flatness, squareness, and edge quality

• Product Marking and Certification

  • Plates, sheets, or strips must be clearly marked with all essential details (specification, alloy, size, manufacturer)
  • Certification and product analysis support traceability and quality assurance

Applications

Nickel-molybdenum alloys covered by ASTM B333-03(2018) are used in environments demanding high corrosion resistance, particularly where exposure to strong acids or other aggressive chemicals occurs. Common applications include:

• Chemical processing plants and equipment
• Pharmaceutical manufacturing
• Food processing units
• Power generation facilities, especially where acid handling is required
• Marine and offshore engineering
• Components for pressure vessels and heat exchangers

These alloys' excellent resistance to pitting, stress-corrosion cracking, and general corrosion make them a preferred material choice for demanding industrial applications.

Related Standards

ASTM B333 is closely linked to several other standards to ensure quality and compatibility throughout the supply chain:

• ASTM B906: General requirements for flat-rolled nickel and nickel alloys plate, sheet, and strip
• ASTM E112: Test methods for determining average grain size
• ASTM E140: Hardness conversion tables for metals relationships
• ASME SB-333: Referenced for boiler and pressure vessel code applications

These related standards support comprehensive testing, dimensional accuracy, and mechanical performance validation, providing a consistent framework for producers and end-users.
