Is the hardness of titanium plate higher than that of stainless steel

Titanium is harder than stainless steel. Titanium plate and stainless steel are common metal materials, but their hardness is different. The hardness range of titanium plates is generally between HB150 and HB340, and the hardness of different models of stainless steel materials will be different. For example, the hardness of AISI 304 stainless steel is generally 187 ~ 223HB, and the hardness of AISI 316 stainless steel in the annealed state is 187 ~ 223HB.

In contrast, the hardness of titanium alloy is relatively high, generally after processing, the hardness is basically about 250~350HV, which is about 20 points of Rockwell hardness HRC, which is slightly higher than 304 stainless steel after solution treatment. In addition, the strength of titanium alloy is also slightly higher than 304 stainless steel, but its density is much smaller than stainless steel, that is, its strength/density ratio is significantly higher than 304 stainless steel.

Therefore, the hardness of titanium plate is indeed higher than that of stainless steel, which makes titanium plate widely used in aviation, chemical, petroleum, machinery, medical and other industries.
