The Specification
What on 300M means on a print — and why it matters.
Electroless Nickel on 300M sits at the intersection of aerospace structural reliability and chemical-process discipline. When it appears on a engineering drawing, the part isn’t a candidate for a generic plating shop. Below is what the callout actually requires.
Electroless Nickel on 300M is Material Science’s Landing Gear Plating Specification 1108 — the customer-controlled standard for electroless nickel plating on landing-gear and adjacent structural-aerospace components built under aerospace programs. It defines the chemistry envelope, deposit characteristics, allowable substrates, post-treatment requirements, and inspection criteria that an electroless nickel deposit must satisfy before a part is accepted into a aerospace assembly.
The specification exists because landing-gear and load-path structural components live at the demanding end of the aerospace duty envelope: cyclic loading, fatigue, corrosive service environments, and tight dimensional tolerance after build-up. A generic "per Electroless Nickel on 300M" deposit doesn’t satisfy Electroless Nickel on 300M by itself — the callout layers ASTM-specific bath-control, hardness, post-bake, and adhesion criteria on top of the public-spec foundation.
What Electroless Nickel on 300M actually controls, in plain English: which platers can run it (only public spec approved processors), how the bath is run (phosphorus content, temperature, pH, replenishment cycle), what the deposit must measure (thickness range, hardness as-plated and post-heat-treat, adhesion), what substrates are allowed, and how the part is post-treated (hydrogen-embrittlement relief bake on high-strength steels; optional heat treatment to elevate hardness). Get one of those wrong, and the part isn’t Electroless Nickel on 300M — even if the deposit looks right.
For procurement engineers, the practical consequence is simple: Electroless Nickel on 300M work must be sourced from a ASTM-approved processor with current NADCAP Chemical Processing accreditation, full traceable lot records, and a quality system that stands up to a customer source-survey audit. Entech is on that list.

| Parameter | Typical Electroless Nickel on 300M Range | Process Notes |
|---|---|---|
| Phosphorus Content | 10.5–13 wt % | High-phosphorus deposit. Maximum corrosion resistance and amorphous as-plated structure. Bath chemistry maintained inside the Electroless Nickel on 300M envelope by daily titration. |
| Deposition Rate | 12–20 µm / hr | Bath temperature (88–92 °C) and pH (4.6–5.0) controlled to deliver predictable plate-time per drawing thickness. |
| Hardness, As-Plated | ~500 HV / ~48 HRC | Amorphous Ni-P matrix. Naturally hard but ductile relative to electrodeposited chromium. Acceptable for service without further heat treatment when drawing permits. |
| Hardness, Post Heat Treat | ~900–1000 HV / 65–70 HRC | Optional precipitation heat treat at 350–400 °C / 1–4 hr precipitates Ni₃P and elevates hardness. Used when drawing calls for hard-EN equivalent to chrome. |
| Typical Thickness Range | 0.0005–0.003″ (12–75 µm) | Per drawing callout. Heavier build-up (up to 0.005″) on engineering review. Thinner values for corrosion-only callouts. |
| Embrittlement Relief Bake | 190 °C / 23 hr min. | Mandatory on high-strength steels (e.g., 300M, AerMet 100, 4340 above 1000 MPa) within 4 hours of plating to release diffused hydrogen. |
| Allowed Substrates | Per Electroless Nickel on 300M § | Carbon & alloy steels, stainless, 300m (with appropriate strike), copper alloys, Invar 36, Inconel, 300M, AerMet, A286, beryllium copper. Each substrate has a controlled prep / activation sequence. |
| Adhesion Test | Bend / Thermal-shock | Sample coupons run with each lot. Visual inspection for blistering, peeling, or cracking after thermal-shock cycle confirms metallurgical bond. |
| Post-Treatment Options | Bake · Heat treat · Polish | Combinations applied per drawing: hydrogen relief, hardness elevation, dimensional polish to print. Selective masking available for non-plated zones. |
| Quality Documentation | CofC + lot data | Each shipment carries certificate of conformance citing Electroless Nickel on 300M, NADCAP audit reference, lot ID, thickness verification, and bake record. |
Note: ranges shown are typical values consistent with public on 300M
guidance. The controlled specification governs the exact requirements for any given
part — Entech runs each Electroless Nickel on 300M lot to the live, current revision of the
specification on file, with full traceability into the spec audit record.

Process Review & Engineering Sign-off
Process engineering matches the substrate to the right preparation, activation, and post-treatment sequence. Hydrogen-embrittlement relief bake and any heat-treat steps are scheduled into the route before the bath.
