304/304L Stainless Steel

At Accumetrics, we proudly offer precision small-diameter tubing crafted from 304 stainless steel hypodermic tube, designated under UNS S30400. This widely used austenitic stainless steel alloy is known for its excellent corrosion and oxidation resistance, making it an ideal choice for high-performance, fabricated tube components. With strong cold working characteristics and high strength, 304 stainless steel is considered the “workhorse” of the 300 series and is trusted by engineers and designers worldwide.

Our 304 stainless steel hypotubing is widely accepted across global engineering standards due to its reliability, availability, and exceptional value. Engineers often favor this alloy because raw strip stock is readily accessible, and it delivers superior performance at a cost-effective price point.

As part of the austenitic family, 304 stainless steel tubing can be hardened only through cold working—not heat treatment—and is commonly referred to as “18-8 stainless” due to its composition of 18% chromium and 8% nickel. These elements provide a protective oxide layer that resists corrosion and self-heals under typical conditions.

At Accumetrics, our 304 tubing is typically supplied in a hard temper condition and is compatible with both traditional and advanced machining processes. Whether you’re using turning, milling, or grinding—or modern techniques like EDM, ECM, or laser cutting—304 stainless steel delivers excellent workability. We also offer 304L, a low-carbon variant, for improved weldability in applications requiring welded assemblies.

304 Stainless Steel Tubing – Features & Applications

We specialize in manufacturing high-quality small-diameter 304 stainless steel hypodermic tubing, known for its versatility, corrosion resistance, and mechanical performance. Our 304 SS tubing is engineered to meet a wide range of industry needs and is commonly used across both medical and industrial sectors.

Common Applications Include:

• Medical devices, including gastroenterology surgical instruments
