430 series stainless steel plate JIS

Grade steel (JIS series) of the general structural steel material of said first portion mainly composed of three parts, such as: S (Steel) said steel, F (Ferrum) represents iron; the 304 stainless portion of said different shapes, types, uses, such as P (Plate), said plate, T (Tube), said pipe, K (Kogu) said tool; third part of that feature figures, usually a minimum tensile strength. Such as: SS400 - S represents the 304 stainless steel plate steel (Steel), said second S "configuration" (Structure), 400 to lower the tensile strength of 400MPa, a tensile strength of the overall means of ordinary structural steel 400MPa.
