Gas Nitriding Job Work in Mumbai — SR Thermal Solution
Are you a manufacturer in Mumbai looking for reliable gas nitriding job work in Mumbai? SR Thermal Solution provides commercial gas nitriding heat treatment job work for Mumbai-based manufacturers from our ISO 9001:2015 certified facility in Chikhali, Pune — just 2.5 hours from Mumbai via the Mumbai-Pune Expressway.
Mumbai is India’s industrial powerhouse. The city and its surrounding areas — Thane, Navi Mumbai, Taloja, Ambernath, Bhiwandi, and Vasai — are home to thousands of forging companies, tool rooms, heavy engineering firms, defence manufacturers, and automotive component suppliers. All of these industries need gas nitriding to improve the surface hardness, wear resistance, and fatigue life of their precision steel components.
However, very few facilities in Mumbai offer dedicated gas nitriding services. Most Mumbai manufacturers must send their components outside the city for heat treatment job work. SR Thermal Solution bridges this gap — we offer fast, professional gas nitriding job work in Mumbai with pickup, treatment at our Pune facility, and return delivery within 5 to 7 working days.

What Is Gas Nitriding Job Work?
Gas nitriding job work is a contract-based surface hardening service. You send your steel components to our facility, we process them in our gas nitriding furnace, and return them with dramatically improved surface properties — all without any dimensional distortion.
The process works by diffusing nitrogen atoms into the steel surface at temperatures between 495°C and 565°C. Ammonia gas breaks down inside a sealed furnace, releasing nitrogen atoms that penetrate the component surface over 15 to 100+ hours. These atoms form extremely hard iron nitrides and alloy nitrides, creating a wear-resistant surface case typically 0.1 to 0.8 mm deep.
The critical advantage is zero distortion. Gas nitriding requires no quenching. Your precision-machined components maintain their exact dimensions after treatment. No warping, no size changes, no post-treatment grinding needed. This is why manufacturers across Mumbai choose gas nitriding job work for their finished, precision components. To learn how nitriding compares with other processes, read our guide to types of heat treatment.
Why Mumbai Manufacturers Choose SR Thermal for Gas Nitriding Job Work
The Mumbai Gas Nitriding Problem
Mumbai has a limited number of gas nitriding facilities. Most heat treatment providers in the Mumbai region focus on conventional processes — hardening, tempering, carburizing, and induction hardening. Dedicated gas nitriding with proper atmosphere control, ammonia flow regulation, and KN potential monitoring is a specialised service that few providers offer.
This means Mumbai manufacturers often face long lead times, inconsistent quality, or must settle for alternative processes like liquid nitriding or plasma nitriding — which may not deliver the same results as controlled gas nitriding.
The SR Thermal Solution Advantage
SR Thermal Solution solves this problem. We offer Mumbai manufacturers access to one of Western India’s largest gas nitriding facilities — a 1,200 kg horizontal gas nitriding furnace with precision ammonia control, PID temperature regulation within plus or minus 1°C, and comprehensive quality testing.
Our Chikhali, Pune facility is just 150 km from Mumbai — approximately 2.5 hours via the Mumbai-Pune Expressway. This proximity means your components can be shipped in the morning and arrive at our facility by afternoon. Many of our Mumbai clients have established a weekly shipping cycle where components are sent Monday and received back treated by Friday. Explore our full range of nitriding jobwork services.

Our address: Gat No-1544, Sonawane Wasti Road, Near Vikas Anath Ashram, Chikhali, Pune 411062, Maharashtra.
Step 3 — Incoming Inspection
Our quality team inspects every incoming component for material verification, surface cleanliness, and pre-nitriding hardness condition. Components that are not in the correct condition (not properly hardened and tempered) are flagged immediately, and we inform you before proceeding.
Step 4 — Gas Nitriding Process
Components are loaded into our 1,200 kg horizontal gas nitriding furnace. The furnace is sealed and purged with nitrogen to remove oxygen. Temperature is raised to 500 to 560°C at a controlled rate. Ammonia gas is introduced at a precisely controlled flow rate using mass flow controllers. The nitriding potential (KN) is monitored continuously. Components are soaked for 15 to 100+ hours depending on the required case depth.
Step 5 — Controlled Cooling
After the cycle completes, the furnace cools gradually under protective nitrogen atmosphere. No quenching is performed. Zero distortion guaranteed. Your components maintain their exact machined dimensions.
Step 6 — Quality Testing
Every batch undergoes comprehensive testing — Vickers surface hardness (HV), Rockwell hardness (HRC), case depth measurement by micro-hardness traverse, and visual inspection. A complete quality report is prepared.
Step 7 — Return Shipment to Mumbai
Treated components are packed with anti-corrosion protection and shipped back to your Mumbai facility. Transit time is 3 to 4 hours. You can also arrange your own pickup.
Total turnaround for gas nitriding job work in Mumbai: 5 to 7 working days from pickup to delivery. Express service available for urgent requirements — contact us to discuss.

FNC and ONC — Advanced Nitriding Services for Mumbai
FNC — Ferritic Nitro Carburizing for Mumbai Industries
FNC introduces nitrogen and carbon into the surface at approximately 570°C, creating a compound layer with superior corrosion resistance. FNC is replacing chrome plating across Mumbai’s hydraulic and automotive industries. It is ideal for brake rotors, cylinder liners, hydraulic valve bodies, fasteners, and marine components. FNC job work for Mumbai clients follows the same logistics as standard gas nitriding — ship to Pune, process, return.
ONC — Oxy Nitro Carburizing for Mumbai Clients
ONC adds controlled oxidation after nitro carburizing, producing a dense black oxide surface. Components get both corrosion protection and an attractive black finish without separate painting. Popular with Mumbai tool makers and fastener manufacturers.
Gas Nitriding vs Chrome Plating — Why Mumbai Manufacturers Are Switching
| Factor | Gas Nitriding / FNC | Hard Chrome Plating |
|---|---|---|
| Environmental | Clean process — zero toxic waste | Hexavalent chromium — toxic, heavily regulated |
| Adhesion | Metallurgical bond — permanent | Mechanical bond — can peel or flake |
| Uniformity | Perfectly uniform on all surfaces | Uneven on complex geometries |
| Internal surfaces | Yes — gas reaches inside bores and holes | No — plating requires line-of-sight |
| Cost trend | Stable, competitive | Rising due to environmental compliance |
| Mumbai availability | SR Thermal — fast turnaround | Multiple platers — inconsistent quality |
| Fatigue strength | Improves by up to 50% | No improvement — can reduce fatigue life |
Multiple Mumbai manufacturers have already switched from chrome plating to FNC through SR Thermal Solution. The switch reduces costs, eliminates toxic waste disposal, and delivers superior component performance.
