Description

The influence of liquid as well as gaseous hydrogen and temperature (-253 to 100 deg. C) on proof and ultimate strength as well as elongation after fracture and reduction of area at fracture for AISI 304, 304L, TP304L, 304LN, TP316NG, 316LN, 321 and 347 was investigated by constant extension rate tests. The effect of temperature on hydrogen embrittlement could be demonstrated. With respect to the dependence on alloy composition seen at 22 deg. C, it is concluded that the main alloy element to look at, if hydrogen embrittlement has to be considered, is nickel accompanied by carbon and nitrogen. The critical region of nickel content seems to be 10.5-11 wt.%
