Stainless Steel 304L HR Sheet Manufacturer and Supplier

Stainless Steel 304L HR sheet is an austenitic chromium-nickel alloy that belongs to the 18-8 family, containing 18.0 to 20.0% chromium and 8.0 to 12.0% nickel. The defining characteristic of 304L is its low carbon content, capped at 0.030% maximum, which gives it superior resistance to intergranular corrosion after welding. 304L HR sheet delivers a minimum tensile strength of 70 ksi (485 MPa), yield strength of 25 ksi (170 MPa), and 35% elongation.

Sachiya Steel International, situated in Mumbai, India, is a trusted manufacturer, supplier, stockist and exporter of Stainless Steel 304L HR Sheet for more than two decades. We offer hot-rolled stainless steel sheets, specifically ASTM A240 / ASME SA-240 Grade 304L, to customers worldwide. We hold ISO 9001, ISO 14001 and ISO 45001 certifications.

The hot-rolled 304L sheet thicknesses range from 3 mm to 100 mm, widths up to 2500 mm, and standard lengths from 1000 mm to 6000 mm, with common stock sizes of 4 ft x 8 ft and 5 ft x 10 ft. It can be welded by TIG, MIG and SMAW. The 0.030% maximum carbon prevents carbide precipitation, so post-weld annealing is not required, and corrosion resistance remains intact after welding.

The material conforms to ASTM A240, ASME SA-240, AMS 5511, and AMS 5513, with wide use in food processing, chemical plants, pharmaceutical production, dairy equipment and architectural cladding.

Industrial Applications of 304L HR Sheet

304L hot rolled stainless steel sheet serves 4 primary sectors: food and beverage, chemical and petrochemical, pharmaceutical, dairy and architectural construction

Food & Beverage Processing Equipment

304L HR sheet is a standard material for sanitary tanks, conveyors and food contact surfaces. Its corrosion resistance meets FDA and USDA hygiene requirements.

Chemical & Petrochemical Industry

Chemical reactors, storage vessels and process piping use 304L HR sheet for resistance to organic and mild inorganic acids. Low carbon content prevents weld decay during thermal cycling.

Pharmaceutical and Dairy Equipment

Pharmaceutical reactors, dairy pasteurisers, and CIP systems are built with 304L HR sheet. The pickled surface supports cleaning protocols required under GMP regulations.

Architectural and Construction

304L HR sheet serves as cladding and structural panelling in construction projects. A matte finish is a sensible choice for outdoor use, especially when a shiny look isn't the goal.

304L vs 304 Stainless Steel HR Sheet

The core difference is carbon content. 304L allows a maximum of 0.030% carbon, while standard 304 permits up to 0.08%. Lower carbon prevents sensitisation during welding and protects against intergranular corrosion.

Parameter	SS 304L HR Sheet	SS 304 HR Sheet
Material Type	Low-carbon austenitic stainless steel	Standard austenitic stainless steel
UNS Designation	S30403	S30400
Carbon Content	Max 0.030%	Max 0.08%
Weldability	Excellent; no need for post-weld heat treatment	Good; may require post-weld annealing
Sensitisation Resistance	High; resistant to carbide precipitation	Lower; prone to sensitisation in the 450–850°C range
Intergranular Corrosion Resistance	Superior	Moderate
Mechanical Strength	Slightly lower than 304	Slightly higher due to higher carbon
High-Temperature Performance	Good, but not ideal for prolonged high-temp service	Better strength at elevated temperatures
Applications	Welded structures, chemical equipment, piping	General fabrication, structural and industrial use
Cost	Slightly higher	More economical

Most sheets are dual certified as 304/304L, meeting both standards and making purchasing easier with one material.

Frequently Asked Questions

What is a 304L HR (Hot Rolled) Stainless Steel Sheet? +

A 304L HR sheet is a hot-rolled, annealed, and pickled austenitic stainless steel sheet, ASTM A240 compliant, with max 0.030% carbon and a No. 1 matte finish.

What is the price of SS 304L HR Sheet per kg?+

It typically costs ₹225 to ₹320 per kg in India. International FOB prices range from USD $2.50 to $4.50 per kg, depending on various factors.

Why choose 304L HR Sheet instead of 304 HR Sheet?+

304L's lower carbon content (a maximum of 0.030% compared to 0.08%) helps to reduce corrosion in the weld area. Therefore, this alloy is beneficial for welded structures, particularly in situations where corrosion resistance is a major concern.

What does the “L” stand for in 304L Stainless Steel Sheet?+

The “L” means low carbon. 304L restricts carbon to 0.030% max, whereas standard 304 allows up to 0.08%, improving weld corrosion resistance.

What are the standard sizes available for 304L HR Sheet?+

Standard dimensions are 4 feet by 8 feet and 5 feet by 10 feet, with thicknesses ranging from 3 mm to 100 mm. We can also accommodate custom sizes, should you need them.

What is the No. 1 finish on a 304L HR Sheet?+

No. 1 finish is hot rolled, annealed, and pickled (HRAP), producing a rough, matte surface suited to industrial applications where appearance is less important.

Can 304L HR Sheet be welded without post-weld annealing?+

Yes. The low maximum carbon content of 0.030% minimizes carbide precipitation. As a result, welds made using TIG, MIG, and SMAW processes maintain their corrosion resistance, even without the need for post-weld annealing.

What industries use 304L Hot Rolled Stainless Steel Sheet?+

It's a common material in food processing, chemical plants, and pharmaceutical manufacturing. You'll also find it in dairy equipment and architectural cladding, where its resistance to corrosion and easy cleaning are big advantages.
