SS grade 904L is a fully austenitic stainless steel, it is less sensitive to precipitation ferrite and sigma phases than the usual austenitic grades with high molybdenum content. SS 904L tubing has unparalleled corrosion resistant properties and is a more genuine and recognized tubing than most other types of tubing out there. The high chromium content exhibits and maintains a passive film which protects the tube in a number of highly corrosive environments. SS 904L tubes also offer accountable resistance to oxidation. To achieve the maximum stress corrosion cracking resistance under critical environments, SS904L is sometimes solution treated which is then followed by cold working.
We stock and outsource tubing from 1/16” to 2”.
There are four types of SS 904L tubing that we manufacture at Instinox:
Hot finished seamless SS 904L tubing (HFS): HFS tubing is manufactured with respect to outer diameter and wall thickness dimensions. It is more cost effective than cold drawn seamless SS 904L tubing. It is used in tubing that requires thicker walls and higher strength.
Cold drawn seamless SS 904L tubing (CDS): CDS tubing offers better machinability, increased strength and tolerances compared to HFS tubing. CDS increases the tubes physical properties.
Electric resistance welded (ERW): ERW process involves spot and seam welding. In ERW the sides are trimmed to control the width and the condition the edges for welding. It is then passed through a number of contoured rollers which cold form the SS 904L into a tube.
Drawn over mandrel (DOM): DOM is not exactly a type of tube, it is more of the process in which the tube is finished. The manufacturing process is almost the same as ERW except that in the end stages the tube is cold drawn over a mandrel.
SS 904L tubes manufactured at Instinox are most widely used in:

We stock and outsource tubing from 1/16” to 2” .
The tubing are marked in requirement of the international standards with the format
BRAND-SIZE-SPECIFICATION-GRADE-HEAT NUMBER-LOT NUMBER
This format helps for identification of the SS 904L Tubing Manufacturers as well is supported with the Material Test Report. This is 100% traceable to the mill from which the material is procured.
SS 904L Tubing is subject to surface wash and cleaning to remove all impurities with it being in stock. Then it is wrapped in thin plastic. The ends are protected by plastic cap to avoid any damage in transit. Then tubing is bundled in bubble wrap followed by assorting them in colored plastic goonies or bundles. Then an outer rope is tied to protect the tubing and they are packed in wooden box or container.
We provide SS 904L Tubing with documents such as commercial invoice, packing list, Test Reports, HS Code, Country of Origin attested by chamber of commerce, Fumigation Certificate, Warranty Letter, and Base Material Certificates.
Each heat and lot of SS 904L Tubing Suppliers is supplied with a material test certificate as per EN 10204 NACE 3.1 standards indicating the chemical and mechanical properties of the fittings along with pressure rating. We also confirm the guarantee of the fittings supplied as per Purchase order specifications and attest the same in the Material Test Certificate. We also welcome any third party inspection from an agency nominated by the customer to comply with NACE 3.2 Certification if required by customer at an extra cost.
At Instinox we target just one thing, the fastest seamless buying experience for our customers.
