ASTM A240 304 Stainless Steel Coil, Stainless Steel 304 Coils, SS 304 Coil Supplier and Manufacturer in Mumbai, India
Abhay Steels manufactures and exports stainless steel 304 coils for buyers who need proven corrosion resistance at scale. This guide covers the metallurgy, testing, and sourcing factors that matter before you place an order.
What Is Stainless Steel 304 Coil?
Grade 304 is an austenitic alloy in the T300 series, built on a chromium-nickel base. It carries a minimum of 18% chromium and 8% nickel, with carbon capped at 0.08%, and carries the UNS designation S30400.
That chromium content forms a passive oxide layer on the surface. The layer self-repairs when scratched or machined, which is why 304 resists rust without any applied coating. Coils arrive in the mill-rolled, unslit form, ready for slitting, forming, or welding downstream.
Grade 304 welds cleanly using most standard methods, and it holds up well under deep drawing without cracking. Toughness stays consistent even at sub-zero temperatures, unlike carbon steel, which can turn brittle in cold service.
The alloy is austenitic, so it does not respond to heat treatment the way martensitic grades do. Instead, it work-hardens under cold working, gaining strength through cold rolling or forming rather than through precipitation reactions. This property makes it useful in applications that call for both formability during fabrication and strength in service. Cleaning stays simple too, since the surface does not pit easily, and standard detergents and water remove most residues without damaging the finish.

Abhay Steels tests raw material before manufacturing and retests the finished coil. Five checks run in the lab: chemical composition, micro- and macrostructure, hydrostatic pressure, alloy verification, and raw material conformity.
Every shipment carries mill test certificates, and clients can request ISO documentation or 100% radiography reports where the application demands it. These documents confirm chemical composition and mechanical properties match the ordered specification, not just the grade name on the invoice.
Manufacturing Process
The coil making process begins with hot rolling the slab to a strip, then cold rolling to final gauge. Annealing restores ductility lost in cold working. Pickling removes the oxide scale formed in heat treating.
Each coil then goes through a testing stage before packing and dispatch.
Why Choose Abhay Steels?
Quality control runs on Total Quality Management and Quality Assurance protocols, applied from raw material intake through final dispatch. Every batch gets chemical and mechanical testing before it leaves the facility, and documentation ships with every order.
That combination of tested material, verifiable paperwork, and consistent process control is what procurement teams check for when qualifying a new coil supplier.

Industries
We Serve
We supply 304 coils to food processing plants because the surface resists acidic and salty ingredients and cleans down without harbouring bacteria in seams.
Architectural firms are another core segment we serve, sourcing coil for panelling, railing, and trim that must survive decades of weather exposure without staining. We also work with fabricators of chemical storage tanks, whose tanks rely on the same passive layer to resist acids and alkalis at ambient temperature.
For heat exchanger manufacturers, we deliver 304 that pairs corrosion resistance with steady thermal conductivity for stable performance across heating cycles. Dyeing industry clients turn to us too, since 304 vessels and piping resist dye chemicals and moisture that would corrode carbon steel and drive up costs.
Domestic tool manufacturers come to us for the same reason architects do: 304 holds a finish and resists daily handling.

Thickness runs from 0.3mm to 8mm. Widths are usually 1000mm or 1500mm, custom widths on request. Covers most jobs, from thin sheet metal work through to heavier tank fabrication.
Mill test certificates are provided on all batches. Chemistry check per ASTM A240 and stock and delivery times before bulk order. Sample test critical projects
Yes. Coils are slit and cut to the sizes a project needs, cutting down on-site wastage. This suits fabricators who want exact dimensions instead of full coils, less handling and storage on their end.
304 has about 8% nickel and 18% chromium. Pricing varies with nickel and chromium levels. Rates are based on the size of the order, finish and thickness.
