Abstract
An end block is disclosed. The end block may include a body extending between a front side, a back side, a left side, a right side, a top side and a bottom side. Furthermore, the body may include a first bore extending through the body between an inlet port and an outlet port and a cylinder bore extending between a cylinder port and the first bore. Moreover, the body may include a precipitation hardened martensitic stainless steel comprising between 0.08% and 0.18% by weight carbon, between 10.50% and 14.00% by weight chromium, between 0.65% and 1.15% by weight nickel, between 0.85% and 1.30% by weight copper, iron, and a first precipitate comprising the copper.
