Hastelloy C22 Round Bar Maharashtra

Anyone who has spent time around chemical plants or pollution-control equipment in Maharashtra has probably run into a situation where regular stainless steel just doesn't cut it. Wet chlorine, sulphuric acid, hot contaminated media — these environments eat through ordinary metals fast, and that's exactly the gap Hastelloy C22 was designed to fill. Delta Superalloys LLP supplies Hastelloy C22 round bars to fabricators, EPC contractors, and process equipment manufacturers across Maharashtra, from Mumbai and Navi Mumbai down to Pune, Nashik, Aurangabad, and the industrial belts around Thane and Raigad. Whether you need a small trial length for a prototype fitting or a bulk order for a full production run, we work off the same stock and the same documentation standards either way.

What Makes Hastelloy C22 Worth the Extra Cost

C22 isn't the cheapest bar stock on the market, and clients sometimes ask if a lower-grade alloy would do the job just as well. Usually the honest answer is no. This alloy was developed specifically to resist a wide range of corrosive chemicals — wet chlorine gas, hypochlorite, chlorine dioxide, sulphuric and hydrochloric acid solutions — where most stainless and even many nickel alloys would pit or crack within a short service life.

It also holds up in both oxidizing and reducing environments, which is unusual. A lot of alloys are good at one or the other, not both. That versatility is exactly why C22 shows up so often in flue gas desulphurization systems, pulp and paper bleaching lines, and pharmaceutical reactors where the chemistry inside the vessel can shift depending on the process stage.

Specifications We Supply

Our Hastelloy C22 round bars are available in the following specifications:

• Standard: ASTM B574 / ASME SB574

Industries We Serve Across Maharashtra

A large part of our client base in the state comes from these sectors:

• Chemical and petrochemical processing units around Thane-Belapur and Taloja
• Pharmaceutical and API manufacturing plants in Pune and Aurangabad
• Pollution control and flue gas treatment equipment manufacturers
• Oil and gas fabrication shops supplying to offshore and onshore projects
• Pulp, paper, and dye industry equipment fabricators

Why Maharashtra-Based Companies Work With Us

Operating out of Mumbai means we're close to most of the industrial clusters in the state, which cuts down transit time considerably compared to sourcing from suppliers further north or south. Beyond logistics, a few things clients mention when they explain why they stayed with us:

• ISO 9001:2015 certified operations
• Genuine, verifiable mill certificates with every dispatch
• Ready stock of common sizes, reducing wait time on urgent orders
• Technical support for grade selection when a client isn't sure what fits their process
• Over two decades of experience in high-nickel alloy supply

Packaging & Delivery

• Export-quality wooden crates and pallets for safe transit
• Standard delivery: 3-5 days (domestic - Maharashtra & India)
• Export delivery: 7-15 days (international)
• Full documentation with every shipment
• Custom packaging solutions available on request

Requesting a Quote

Round bar pricing depends on diameter, length, quantity, and testing requirements, so we don't quote a flat per-kg rate publicly — it moves too much between projects to be meaningful. Send us your size and quantity requirement, along with any applicable standard or certification need, and we'll get back with pricing and lead time. You can contact us through the website form, over WhatsApp, or by phone.
