Tubular Grade Comparison Principles

Compare grade systems responsibly without assuming that similar strength levels are interchangeable.

MATERIAL SELECTION GUIDE

Tubular Grade Comparison Principles

Grades with similar yield strength are not automatically equivalent. A responsible comparison considers the complete specification, chemistry, manufacture, heat treatment, properties and acceptance rules.

01

Compare the full definition

Strength is only one part of a material grade.

  • Chemical composition
  • Yield, tensile and elongation
  • Impact toughness
  • Hardness and heat treatment
02

Check product and service context

A designation valid for one product form or service may not transfer to another.

  • Product standard and edition
  • Manufacturing route
  • Dimensions and test locations
  • Sour, low-temperature or offshore duty
