A series of elevated temperature creep tests have been carried out to determine relevant creep data, which is The stress-strain curves for some of the elevated temperature tensile tests are shown in Figure 3.

Considerations of space and. The tensile strength of martensitic stainless steel (S45 to BS ) is obtained by hardening and tempering, and it is used for springs above 5mm wire diameter, either in corrosive environments or where resistance to creep or relaxation is required; its performance in this latter respect is very similar to that of the austentic.

However, values of these properties at different temperatures are not well reported. Therefore, both steady and transient tensile coupon tests were conducted at different temperatures ranged approximately from 20 to °C to obtain the mechanical properties of cold-formed steel structural material.

As the strengthening mechanism for cold-drawn steels is quite different to that of quenched and tempered steels, I would have expected that the elevated temperature behaviour of the two would vary.
