304 Stainless Steel Pipe: Sizes, Price & Supplier Guide

Looking to buy 304 stainless steel pipe? This guide covers why 304 is the default austenitic pipe grade, the sizes and schedules we stock, what drives the price, and how to pick a reliable supplier — with a fast quote at the end.

Why Choose 304 Stainless Steel Pipe

304 (ASTM A312 / A269) is the workhorse 18-8 austenitic grade — about 18% chromium and 8% nickel. It gives excellent corrosion resistance in most atmospheres and many chemicals, good weldability and formability, and a lower price than 316 because it carries no molybdenum. For general plumbing, structural and process lines below roughly 60°C and in non-chloride duty, 304 pipe is the sensible default.

Sizes, Schedules & Surfaces

We stock seamless 304 pipe from 1/8″ to 24″ (DN6–DN600), schedules 5 / 10 / 40 / 80 / 160 / XXS, in AP, BA and pickled surfaces. Standard lengths are 6 m (12 m on request). Wall tolerance follows ASTM A999; every pipe is UT and hydrostatic tested. Both seamless (for pressure) and welded (for low-pressure) versions are available.

304 Pipe Price Factors

Price per kg tracks the nickel and chromium surcharge plus mill conversion. Schedule (wall thickness) and diameter set the weight — heavier walls cost more. Surface finish (BA above pickled) and testing add cost. Volume and full-container loads earn deeper discounts. Send your specification for a current USD/kg quote; our 100,000-ton stock means fast shipment.

Typical Applications

Food and dairy lines, breweries, potable-water and architectural handrails, heat exchangers, pharmaceutical and cosmetic process piping, and decorative or structural frames. 304 is the default wherever corrosion is mild and cost matters more than maximum grade.

How to Choose a Supplier

Request MTC (EN 10204 3.1), confirm the ASTM grade and schedule, and verify stock depth and lead time. A stocked, ISO/TS16949-certified supplier with 100,000 tons and cut-to-length plus third-party inspection covers both trial lots and full containers.
