AStainless Steel 409M Coils belong to the ferritic stainless steel family, developed for applications requiring dependable mechanical strength, reliable weldability, excellent formability and stable performance under elevated-temperature service. Catalytic converters, mufflers, furnace components and general industrial fabrication also rely heavily on this grade. Abhay Steels manufactures, supplies, stocks and exports SS 409M Coils to engineering, agricultural and construction sector customers within India and across export markets. Every coil is produced in line with ASTM A240 and ASME SA240 specifications, giving buyers a consistent basis for chemical composition and mechanical property verification.

SS 409M carries 10.5 to 11.75 percent chromium, low enough to keep material cost below the austenitic grades while still forming a stable protective oxide layer. Under ASTM A240, this grade family carries a minimum tensile strength of 380 MPa, a minimum yield strength of 205 MPa, a minimum elongation of 20 percent, and a maximum hardness of 88 HRB. Abhay Steels stocks both hot-rolled and cold-rolled coils, finished to 2B, 2D, BA, and satin surfaces, in soft, half-hard and full-hard conditions. Thickness runs from 0.3 mm to 8 mm, and width is up to 1500 mm, with standard and custom coil lengths on request. Slitting, shearing, laser cutting, and cut-to-size processing happen on-site before dispatch, so buyers receive coil stock ready for their production line.

Automotive component manufacturers specify SS 409M for exhaust piping, catalytic converter shells and muffler bodies, where thermal cycling resistance exceeds resistance to aggressive chemical media. Oil and gas, chemical processing, power generation, food processing and general engineering fabrication units use the same grade for furnace linings, heat exchangers, and structural parts exposed to moderate heat loads. Each batch leaving Abhay Steels comes with PMI verification, hardness testing, full chemical analysis and macro and micro examination; pitting resistance and intergranular corrosion testing are available for critical-service orders. Mill test certificates, inspection reports and supporting documentation travel with every shipment. Coils are packed for road and sea freight alike, with heat-number traceability maintained from mill release through to final delivery, domestic or export.

Why Choose Abhay Steels for SS 409M Coils?

Abhay Steels functions as a manufacturer, supplier, stockist and exporter of SS 409M Coils and keeps sufficient stock across common thicknesses and widths for immediate delivery. Buyers can specify multiple finishes, hardness conditions and both standard and custom sizes without waiting for a fresh production run. In-house cutting, shearing, slitting and laser-cutting facilities shorten turnaround on cut-to-size orders. Every dispatch carries MTCs, inspection reports and heat-treatment records alongside the required quality testing. Packaging is built for the transit distance involved, whether it's a domestic delivery or an export shipment crossing several ports. Engineering, agricultural, and construction sector buyers in India and abroad source SS 409M Coils from Abhay Steels for this combination of stock availability, technical documentation and processing support.

409M SS Coils

Construction of AISI/SS 409m Coils:
The coils got constructed using high profile raw material. The awaited stainless steel coils possess a tremendous property that has high-quality attributes. The coil got manufacturing austenitic steel which is soft in nature. The coil has a flawless finish with good quality of machining and desired structure.

The 409M coil is lightweight as well as easy at forming purpose. The coil will have excellent tensile strength and it is easy at welding with a fusion welding technique. They are made in such a way that it is high in corrosion-resistant toward reducing agents and oxidizing agent at atmospheric condition. In addition, the coil is also resistive toward high-pressure steam and gases. Manufacturing is then followed by testing.

Test certificates-
The Stainless steel 409M coils undergo test like PMI, pitting resistance test, Macro & micro test, chemical/spectro analysis, flaring test, hardness test, and IGC test. Once the coil passes these test, it got certificates as a radiography test report, third-party report, buyer test report & raw material certification.
