Stainless Steel ERW Pipes Material and Grades

What Is the Difference Between Stainless Steel ERW Pipes and Stainless Steel EFW Pipes?

The difference is the weld and the starting material. ERW pipes start as coil and weld with high-frequency current and no filler, so the mill can run long, fast, continuous lengths in small to medium sizes. EFW pipes, short for electric fusion welded, start as plate and weld with arc welding and filler metal, so they reach very large diameters and heavy walls. The EFW standard is ASTM A358.

Choose ERW for sizes up to 24 inches, thin to medium walls, and tight budgets. Choose EFW for large diameters, thick walls, and heavy-duty process lines.

Stainless Steel ERW Pipes Chemical Composition

Chemistry sets corrosion resistance, strength, and weldability. Values are weight percent. For each grade in the first table, read down the column.

Stainless Steel ERW Pipes Mechanical Properties

Mechanical properties show how much load the pipe carries before it stretches (yield) or breaks (tensile). Values are minimum.

Stainless Steel ERW Pipe Size and Weight Chart

ERW stainless pipes lean toward thin walls, so the first chart covers the lightest ASME B36.19M schedules, 5S and 10S. The second chart covers OD-based pipes used for handrails, frames, and fittings. Weights are for 304 stainless steel at 7.93 g/cm³. Pipes in 316 weigh about 1% more.

Schedule 5S and 10S Pipes

OD-Based Round Pipes, Weight in kg per Metre

To work out the weight of any size, use Weight (kg/m) = (OD − Wall) × Wall × 0.02491 for 304, with both values in mm.

Common Materials

Different stainless steel grades offer different levels of corrosion resistance, strength, temperature resistance, and cost. Stainless steel ERW pipe suppliers can provide these grades based on the application, required standard, and surface finish.

Grade 304: The most widely used stainless steel grade. It contains about 18% chromium and 8% nickel and offers good resistance to water, food, and mild chemicals.

Grade 316: Contains around 2% to 3% molybdenum, giving it better resistance to chlorides, coastal environments, brine, and cleaning chemicals.

Grade 304L: A low-carbon version of 304. Its lower carbon content helps maintain corrosion resistance in the weld area.

Grade 316L: A low-carbon version of 316 that provides good corrosion resistance after welding and suits demanding process applications.

Grade 321: A titanium-stabilized grade designed for elevated-temperature applications, generally from about 425°C to 850°C.

Grade 347: A niobium-stabilized grade that performs well in high-temperature and welded applications.

Grade 904L (UNS N08904): Contains higher amounts of nickel and molybdenum, making it suitable for demanding acidic and corrosive environments.

Grade 201 (UNS S20100): Uses manganese and nitrogen to replace some nickel. It offers a lower-cost option but has lower corrosion resistance than 304.

Grade 202 (UNS S20200): Similar to 201, with manganese and nitrogen replacing some nickel. It is mainly suitable for indoor and decorative applications.

Grade 430 (UNS S43000): A magnetic ferritic stainless steel with no nickel, commonly used for indoor, decorative, and general applications.

When ordering, specify the grade, applicable standard, and surface finish together. Two pipes may look similar but can perform very differently depending on their stainless steel grade.

Available Sizes, Dimensions and Schedules

We supply stainless steel ERW pipes from 1/2" to 24" NPS in schedules 5S, 10S, 40S, and 80S, and OD-based pipes from 19.05 mm to 101.6 mm in walls from 1.0 mm to 3.0 mm. A schedule is a code for wall thickness, so the same schedule gives a different wall in mm at each pipe size, while the outside diameter stays fixed for each NPS. Handrail and furniture pipes follow OD and wall in mm instead of schedules, and the tolerance class decides how neatly the pipe fits fittings and couplers.

Standard lengths are 6 m, 20 ft, and random lengths, and we cut to exact length. As a stainless steel ERW pipes supplier in India, we hold common grades and sizes in stock, subject to availability.

Stainless Steel ERW Pipes We Manufacture and Supply

Our range as a stainless steel ERW pipes manufacturer covers 304, 304L, 316, 316L, 321, 347, and 904L pipes for process lines, plus 201, 202, 304, and 430 pipes for handrails, gates, frames, and trim. We make annealed and pickled pipes, bright annealed pipes, satin finish pipes, mirror polished pipes, square and rectangular pipes, and sanitary pipes for dairy and brewery lines. Each pipe leaves with a clean, wrapped surface where polish matters, plus the heat number, grade stencil, and test reports your standard requires.

Applications of Stainless Steel ERW Pipes
