Titanium plate can meet the requirements of 100hrb
At room temperature for the austenite, quenching process can not be hardened, can be treated with nitriding surface hardening, but the depth is very limited
HRB100 degrees quite HRC22.8, quite Brinell hardness HB241, hardness can be achieved
304 stainless steel is the US standard. SUS304 is a Japanese standard. Equivalent to our 0Cr18Ni9
