Interpretation of D665B Steel

Interpretation of D665B Steel Recently, Xing Steel's steelmaking plant produced D665B steel. Here are some simple interpretations of D665B steel:

D665B is affiliated to the nickel-refining austenitic stainless steel. It is necessary to add a large amount of Mn element to ensure the stability of the metallographic structure on the basis of no or less addition of Ni element. In certain situations, D665B steel can replace expensive 300 series austenitic stainless steel. However, due to its high Mn content, it is necessary to add a manganese alloy to the furnace once during the smelting process in the AOD furnace, and the smelting problems such as unbalanced process temperatures are likely to occur. To this end, based on the experience of summarizing the 400 series stainless steel, the plant formulated a practical production plan such as “AOD Furnace Smelting D665B Operation Standard” and “Process Temperature Model Calculation”, and monitored each of the smelting processes from a theoretical and practical perspective. One link. It is reported that because the steel can replace 300 series austenitic stainless steel in certain occasions, the market demand is large.
