Subject: Request to yield values for the steel grades TTStE 36 to SEW
089-70 and for steel grade TTSt 35 N to SEW 680-70, at 50 ° C. Dear Mr
Bathula,

We regret but the technical informations SEW 089 and SEW 680 contains
not yield stress information by 50 ° C. So we can not give you any
information.

Perhaps the following information will help you further.

TTStE 36 to SEW 089-70
<= 16 mm 36 kg/mm2 yield strength at room temperature +20 ° C.

TTSt 35 N to SEW 680-70(valid for longitudinal samples)
<= 10 mm wall thickness or diameter 23 kg/mm2 yield strength at room
temperature +20 ° C.

Yours sincerely

Can anybody provide where can I get the allowable stresses and mechanical properties of this material, particularly we are looking for yield stress value  of following material at 50 °C.
