1. Key words: code calibration, geometric properties, reliability, steel, tensile strength, yield strength.

2. Low alloy steel with a high yield strength and high sulphide stress cracking resistance

3. Yield strength is the lowest stress that produces a permanent deformation in a material.

4. Re= yield strength in N/mm2, or 0,2 % proof strength or, for austenitic steels, 1 % proof strength;

5. Aluminized steel was developed for providing more structural durability and a high yield strength in highly corrosive environments

6. The steel product may have an increase in elongation and an increase in yield strength after age hardening.

7. Creep is a time-dependent deformation of a material while under an applied load that is below its yield strength

8. As the temperature falls below # °C the ultimate strength (Rm) and the yield strength (Rp # ) increase slightly for all aluminium alloys (see figure

9. Measured yield strength of line pipe is used to determine the pipe grade of every pipeline section referring to technical standard API 5L.

10. The yield strength of pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa.

11. Front Axles Forged from 4340 material & heat treated for high tensile and yield strength. Increased material in the yoke area for added strength

12. As the temperature falls below 0°C the ultimate strength (Rm) and the yield strength (Rp0,2) increase slightly for all aluminium alloys (see figure).

13. Strain-Ageing is known to cause an increase in yield strength and ultimate tensile strength of reinforcing steel bars, while tensile elongation capacity will be less in strain-aged steel bars

14. Except for UN No 1001 acetylene, dissolved, the permissible maximum stress of the manifolding arrangement at the test pressure of the receptacles shall not exceed 75 % of the guaranteed yield strength of the material.

15. Exposed Bolting (High Strength) ASTM A453/A453M Grade 660D solution - treated and age hardened Bolting shall be acceptable at a hardness o f HRC35 and lower, and a minimum 0.2 % offset yield strength of 725 MPa (105,000 psi )
