WebThe 316 family is a group of austenitic stainless steels with superior corrosion resistance to 304 stainless steels. They also have excellent toughness and can be used in the food, marine, chemical and architectural fields. Other applications include fasteners and screens for the mining industry. WebStandard ASTM C835-06 was used to measure the total hemispherical emissivity of structural materials of RPV. The bell jar emissivity was measured using 304 stainless steel strips coated with black paint (Aremco HiE-Coat 840 M). Testing these strips verified that the internal bell jar emissivity is greater than 0.8 as required by the ASTM standard. inwentaryzator 3 1 https://blahblahcreative.com
