Stainless Steel 304H Seamless U Tube

A Stainless Steel 304H Seamless U Tube is a type of tubing made from stainless steel grade 304H, a high-carbon version of the 304 stainless steel alloy. The "U" shape refers to the tube's configuration, which resembles the letter U, making it suitable for certain applications where a U-shaped design is necessary. "Seamless" indicates that the tube is formed without any welded seams, which can provide advantages such as increased strength and resistance to corrosion. This type of tubing is often preferred in applications where leakage or contamination from welded seams is a concern.

Stainless steel 304H is a versatile austenitic stainless steel alloy with higher carbon content than standard 304 stainless steel. This higher carbon content provides increased strength and high-temperature resistance, making it suitable for applications with elevated temperatures.
