304, 316, 17-4 PH and other stainless grades on the shop floor.
CNC Machining for Oil and Gas Parts: What Wellheads and Auditors Actually Require
How pressure retaining parts are actually machined and released: the stainless, duplex and nickel alloy list behind wellhead and pipeline hardware, why sealing faces and premium threads get their own rules, what an EN 10204 3.1 documentation pack contains, where turn mill and five axis setups cut cost, and how sour service changes the plan.

Stainless Steel Machinability: 303, 304, 316 and 17-4 PH Compared
Why the stainless family machines so differently: the sulfur that makes 303 free cutting and unweldable, the work hardening that punishes a hesitant cut in 304 and 316, the condition sequence that decides whether 17-4 PH is easy or miserable, and the arithmetic behind a 30 percent price difference for the same geometry.
