Mada Santetsu stainless steel plates, Mada Santetsu stainless steel structural materials and parts

Abstract

The stainless steel plate of this case has a predetermined chemical composition; in the chemical composition, the total of C and N is 0.050~0.110%, and the Ms point shown in the following formula (1) is 50~100; when the plate thickness is set to t (mm), the residual ferroalloy area ratio of the cross section (L section) parallel to the rolling direction and the plate thickness direction is as follows: 1.5~5.0% at the 1 / 2t position and 1.0~5.0% at the 1 / 8t position. Ms=550-361C-28Si-39Mn-10Cu-17Ni-20Cr-5Mo・・・(1)
