氢对低合金钢上不锈钢堆焊层性能的影响
Effect of hydrogen on the behaviour of stainless steel weld overlay cladding applied to low alloy steel
摘要
Abstract
The investigation on slow strain rate testing(SSRT) of the weld overlay cladding of 309L and 347L in original and hydrogen charged conditions indicated that 1.For original specimens,the fracture of both smooth and notched specimens occurred in the 347L region,but if specimen charged with hydrogen the fracture changed in 309L region.2.Hydrogen decreases the strength and ductility of 309L and 347L.After thermally charging with hydrogen the fracture stress dropped from 885MPa to 478MPa for 309L and from 799.9MPa to 564MPa for 347L and hydrogen embrittlement indices were 86.8% and 80.9% respectively.关键词
