Along with lengthening the sevicing time of boiler tubes made from 18-8 type austenitic stainless steel
the degree of micro-stucture ageing and performance deterioration become more serious
the change of micro-structure property may lead to embrittlement of materials
and decrease of materials' corrosion resistant ability etc..Based on tests of micro-structure property variation
the microstructure's ageing property and ageing degree of 18-8 austenitic stainless steel can be divided into five grades:grade 1-non ageing;grade 2-slightly ageing;grade 3-moderate ageing;grade 4-fully ageing;and grade 5-serious ageing.The micro-structure property of each grade of ageing has been given.
