WebJan 12, 2024 · The Rockwell hardness of 304 stainless steel sheet is HB ≤187 HRB≤90 HV≤200. Factors related to the Rockwell hardness of stainless steel: 1. There will be stress on the product after rolling, folding, etc., which will affect the hardness, and the solution treatment will also have an impact. 2. The most important thing is the material of ... WebA lower stress relieving temperature of 400°C maximum must be used with 304 SS with longer soaking times. If, however, stress relieving is to be carried out above 600°C, there is a serious threat of grain boundary sensitization occurring with a concomitant loss in corrosion resistance.
WebThis stainless steel grade shows good ductility in the annealed condition, and can be readily drawn and formed. Hardness and strength can be improved through cold working. 304/304L demonstrates excellent corrosion resistance. One disadvantage of 304 is that it is non-hardenable by heat treatment.
